OBJECTIVE

The objective of this project was the evaluation of the stability upon thermal

cycling and handling of ten small, epoxy-encapsulated silicon diode

ft thermometers (Model DT-500FP-HRC-7 from Lake Shore Cryotronics, Inc.) at six

temperatures in the range from liquid nitrogen temperatures to about 60 °C .

The nominal temperatures of measurement were - 196 °C, -78 °C, 0 °C, 20 °C,

40 °C, and 60 °C, as measured on the International Practical Temperature Scale

of 1968. Diodes were to be thermally cycled 15 to 20 times. Since NASA

anticipates that the uncertainty in their temperature measurements will be

t 50 mK, uncertainties as large as t. 10 mK in the measurements of our

evaluation can be accommodated without deleteriously affecting the value of

the results of the investigation.

Certain commercial equipment, instruments, or materials are identified in

this paper in order to adequately specify the experimental procedure. Such

identification does not imply recommendation or endorsement by the National

Bureau of Standards, nor does it imply that the materials or equipment

identified are necessarily the best available for the purpose.

ABSTRACT

An investigation of the stability of 10 silicon diode thermometers upon

normal handling and upon thermal cycling between liquid nitrogen temperatures

and 60 °C was conducted. The diodes underwent 28 thermal cycles and during

that time, only one experienced instabilities equivalent to as small as

t 0.045 K. The other nine diodes had instabilities which ranged from about

± 0.09 K to + 0.20 K.

INTRODUCTION

The surface temperature of airfoils must be known accurately in order to

properly investigate and evaluate aircraft designs. Models are usually tested

in a facility such as the National Transonic Facility located at the Langley

Research Center of NASA, in which cold nitrogen gas is used as the fluid. The

surface temperatures of interest are usually in the range from about 77 K to

1
325 K. In order to accurately measure the surface temperatures of the

airfoils, adequately characterized thermometers must be employed. The types

of thermometers available for such measurements are limited; they must be

small, rugged, sensitive, stable, and respond rapidly. One thermometer that

might possibly meet these requirements is the silicon diode thermometer.

The objective of this project was to determine the stability upon thermal

cycling and handling of ten small, epoxy-encapsulated silicon diode

thermometers at six temperatures in the range from liquid nitrogen

temperatures to about 60 °C. The nominal temperatures of measurement were

-196 °C, -78 °C, 0 °C, 20 °C, 40 °C, and 60 °C.

EXPERIMENTAL DETAILS

Equipment Used In Investigation

thermometry

The temperatures at which tests were conducted were measured with a longstem standard platinum resistance thermometer (SPRT) [1] which had been

calibrated at the National Bureau of Standards in the Platinum Resistance

Thermometer Calibration Laboratory. The resistances of the SPRT were measured

with a Neil Brown Instrument systems, Inc. automatic ac resistance bridge* [2]

that has a resolution of 0.1 mK.

^Certain commercial equipment, instruments, or materials are identified in

this paper in order to adequately specify the experimental procedure. Such

identification does not imply recommendation or endorsement by the National

Bureau of Standards, nor does it imply that the materials or equipment

identified are necessarily the best available for the purpose.

2
temperature-regulated environments

The thermal environments of the diodes were provided by different

methods, depending on the temperature of measurement. For all cases, except

at liquid nitrogen temperatures, the diodes were immersed in a low-viscosity

silicone oil during measurements. At liquid nitrogen temperatures, the diodes

were immersed directly in the liquid nitrogen. During measurements at each of

the temperatures, the SPRT was located in the fluid with, and encircled by,

the 10 diodes under test.

At - 78 °C, the refrigerant was solid CO2 in alcohol. During the

measurements at this temperature, the diodes and the SPRT were immersed in the

low-viscosity silicone oil in a brass cylinder that was surrounded by the

refrigerant. The silicone oil was stirred by means of a magnetic stirrer

which was well removed from the diodes.

At 0 °C, an experimental arrangement similar to that used at -78 °C was

employed, except that the refrigerant in this case was ice.

During measurements at the three temperatures just discussed, the

temperatures were not regulated with a temperature controller but,

nevertheless, they were constant to within 2 or 3 mK.

At temperatures above 0 °C, the thermal environments were provided by a Rosemount Inc. oil bath, in which the temperatures were regulated with a

Tronac, Inc. Temperature Controller. The temperatures were constant to 1 or

2 mK over the time of the measurements.

3
voltage measurements

A Cryocal, Inc. constant current source, Model CS 1000B, was used to

supply the 10 uA current required by the diodes. This unit provided a

current with an instability of at most 10 ppm. The voltages across the diodes

were measured with an HP 3456A Digital Voltmeter (DVM). A scanner, HP Model

3495A, was used for switching the appropriate potential leads of the diodes to

the DVM. Similar but upgraded versions of these latter two instruments were

purchased to be incorporated by NASA personnel in an automated system at NASA.

Those instruments purchased are listed in Table 1. The measurements which we

conducted on the diodes were automated to a great extent.

The current that passed through the diode thermometers was monitored by

measuring the voltage across an ESI standard resistor, Model SR 104, that was

connected in series with the diodes. The SR 104 is a transportable 10,000 ohm

standard resistor with a small but known temperature dependence. The voltages

across the SR 104 were measured with the DVM.

diodes

The diodes investigated were those specified by NASA, and are listed in

Table 2. In our measurements, the 10 silicon diodes were wired as 4-lead

devices. They *ere connected in series with each other and with the constant

current source. The potential leads of each diode were connected to the DVM

through the scanner. Two of the diode thermometers were calibrated by the

supplier prior to delivery (see Table ?).

4
Experimental Arrangement

Since the small silicon diode thermometers that we investigated for

stability upon thermal cycling and normal handling were tested over the range

from liquid nitrogen temperatures to 60 °C, different techniques were used

above and at or below 0 °C. For testing at liquid nitrogen temperatures, the

10 diodes were inserted into small wells of a 2-cm deep wooden ring which was

attached by means of three small thin-walled stainless steel tubes to a top

Dewar-cap assembly. For solid CO 2 temperatures and at 0 °C, an assembly

similar to that used at liquid nitrogen temperatures was used except that the

bottom ring was lucite instead of wood and, additionally, the diodes extended

through the ring by about 2 cm. These support systems were fitted into either

Dewars or other containers which contained either liquid nitrogen or a lowviscosity silicone oil during tests. In order to avoid large thermal shocks,

the diode assembly was inserted slowly into the relevant fluid. In the case

of liquid nitrogen, the wooden holder also aided in slowing the cooing of the

diodes.

For tests above 0 °C, the diodes were held in position in the oil bath by

a thin ring of lucite through which small holes had been drilled to

accommodate the diodes. The diodes were located such that they extended about

3 cm below the lucite ring.

During measurements above, at, and below 0 °C, the SPRT was located such

that the platinum sensing element was at or near the same vertical position as

the diodes and along the axis of the wooden or plastic rings. Although the

fluid baths, with the exception of the liquid nitrogen bath, were stirred and,

thus, were uniform in temperature within 1 to 3 mK throughout the baths, this

5
arrangement of SPRT and diodes further ensured that the temperature measured

with the SPRT was very nearly the same as that experienced by the diodes.

Experimental Procedure

The thermal cycling of the diodes was performed by cooling them to liquid

nitrogen temperatures and then making measurements on them; removing the

diodes from liquid nitrogen, blowing room-temperature air over them to warm

them to room temperature and remove any moisture present, placing them in the

lucite holder, inserting them into room-temperature oil followed by inserting

them in an oil bath at solid CO2 temperatures and making measurments on them;

removing the diodes from the oil at solid C0 2 temperatures, blowing roomtemperature air over them to warm them to room-temperature and remove any

moisture present, inserting them in room-temperature oil, then inserting them

in an oil bath at the ice point and making measurements on them; removing the

diodes from the oil at the ice point, placing them in the holder for use in

the temperature-regulated oil bath, placing them in an oil bath at 20 °C and

making measurements on them; and then heating the temperature-regulated oil

bath containing the diodes first to 40 °C and then to 60 °C and making

measurements respectively at those temperatures. When measurements at 60 °C

were completed, the diodes were removed from the oil bath and left at room

temperature overnight, ready to repeat the process the next day. Each

experiment with the diodes experiencing temperature changes as just described,

i.e., from room temperature to liquid nitrogen temperature to room temperature

to solid C02 temperature to room temperature to the ice point temperature to

6
room temperature to 20 °C to 40 °C and to 60 °C, constituted one thermal

cycle. A given thermal cycle was conducted over a period of one day and it

required a full day of work.

RESULTS AND DISCUSSION

We encountered numerous measurement problems during the first several

thermal cycles. These were related to earth loops and pick-up. Although one

never totally eliminates such problems with diodes since they are rectifiers,

the problems can be and were reduced to manageable levels. In our case, after

the appropriate shielding and grounding, those problems accounted for changes

amounting to the equivalent of only a few mK (i 5 mK, maximum). We found that

it was necessary to use shielded cables exclusively and to ground all of the

equipment involved in the measurements at one point only. It is desirable to

shield the leads to the diode thermometers over their entire length, but that

is not generally practicable, however, if the diodes are to be used as

thermometers. They can be shielded, however, over most of their length and,

in our case, the unshielded portions were located inside the fairly-wellenclosed thermal environment. In this investigation, some 11 thermal cycles

were performed before we were sufficiently satisfied that our reduction of

these sources of uncertainty was adequate. We then obtained stabiity data for

17 thermal cycles, labelled cycles 12 through 28.

Data obtained for the 10 diode thermometers during the thermal cycle

experiments numbered 12 through 28 are presented in Table A1 in the appendix.

Although the temperatures in the liquid nitrogen, solid C02 and the ice point

7
baths were uniform and stable to within 2 or 3 mK during any given experiment,

there were larger variations from day to day. These were due to various

causes, one of which was changes in atmospheric pressure. Such variations

were not present in the temperature-regulated oil bath used at the higher

temperatures. Consequently, the data obtained at 20 °C, 40 °C and 60 °C on

different days for each diode thermometer may be compared directly without

having to make any corrections for small differences in bath temperature.

The results obtained for the 10 diode thermometers at 20 °C for thermal

cycles 12 through 28 are presented in Figures 1-10; those obtained at 40 °C

are presented in Figures 1 1-20; and those obtained at 60 °C are presented in

Figures 21-30. The sensitivity of the diodes at these temperatures is

approximately - 2.85 mV/K. Consequently, one can see that at 20 °C the total

variation among the 10 diodes ranged from the equivalent of about 265 mK to

370 mK. The mean value was approximately 310 mK, or ± 0.155 K. Diode number

10 appears to be by far the most stable but there was one datum point, the

point for thermal cycle number 25, which was very different from the other

values and can probably be considered an outlier and thus can be ignored.

Except for that point, the variation for diode number 10 is about * 0.045 K.

The data obtained for the 10 diodes at 40 °C varied by the equivalent of

from about 90 mK to 280 mK. The mean value was about 210 mK or * 0.105 K.

Diode number 10 was substantially more stable than the other diodes, its

instability being ± 0.045 mK. The instabilities for the other nine diodes

were clustered around the value + 0.114 K, more than twice that for diode

number 10.

The data obtained for the 10 diodes at 60 °C varied by the equivalent of

from about 90 mK to 385 mK, with a mean value of about 300 mK or * 0.150 K.

8
Except for diode thermometer number 10, all of the diodes behaved in a

comparable manner, with their instabilities clustered around a value of about

+ 0.16 K. Diode number 10 was consistently more stable than the other diodes

and was more in line with what one would expect to obtain. Its instability

was ± 0.045 K. Diodes numbered 9 and 10 were the ones which the supplier

had calibrated prior to delivery.

Although we have not presented any graphs of data at temperatures below

20 °C, it can be seen from the data of Table A1 that instabilities at those

temperatures are comparable to those discussed above.

As can be seen from the figures and as indicated above, the diodes

exhibited substantially greater stability at 40 °C than they did at the other

temperatures. The reason for this is not understood. The nonuniformity and

instability of the temperature in the oil bath can not explain this behavior

because there is essentially no difference in the quality of these features at

20 °C, 40 °C and 60 °C. Furthermore, even if the instability of the

temperature-regulated oil bath were greater at 20 °C and 60 °C, the magnitude

of the difference would be only a few millikelvins and, thus, could not

account for the large differences observed for the diodes. Handling the

diodes can't account for the differences in behavior at the different

temperatures above 0 °C either since the diodes were not removed from the oil

bath between measurements at those temperatures. Thermal shock can't account

for the differences either since the diodes were not removed from the oil bath

during the time the temperature of the bath was being changed from one

temperature to the next and the amount of time required for the bath to come

to a new (higher) test temperature and reach equilibrium was about one hour.

The calibration data provided by the supplier for diodes 9 and 10 are

9
given in Tables 3 and 4, respectively. These may be compared with the data

obtained in our investigation. It appears that the calibration data for diode

number 9 is not, in fact, for number 9 since the values given in the table are

far different from those that we obtained. The calibration table for diode

number 10 is probably for that diode but the calibration was really quite

inaccurate

.

CONCLUSIONS

The instabilities of the 10 small epoxy-encapsulated diode thermometers

upon thermal cycling between liquid nitrogen temperatures and 60 °C and upon

normal handling were considerably larger than we had anticipated. Based on

conversations with suppliers, we had anticipated instabilities on the order of

i 10 mK. Our results indicate that the instabilites, in general, are some 10

to 20 times larger. In addition to the problems of instabilities, special

care must be taken when using diode thermometers to reduce the possibility of

pick-up. This latter problem can be reduced to manageable levels, however.

Diodes generally have been used at cryogenic temperatures and it may be

that if they were mounted in a cryostat or on some massive support such that

they would be cooled much more slowly than that accomplished in the

experiments reported here, they might be considerably more stable than those

observed in these experiments and they might live up to our previous

expectations. In the experiments at NASA in which the use of diodes is

contemplated, the rate of cooling of the thermometers would probably be much

less than what we attained.

10
Silicon diode thermometers of a construction other than the small epoxyencapsulated ones might be more stable. Those mounted in a BeO ceramic header

set into a gold-plated copper cylinder with epoxy lead strain relief or those

mounted in a TO-46 package might put less strain on the diode and its

connections to the leads and thus yield greater stability. Diode thermometers

of such construction should be tested and they should be tested by cycling to

liquid helium temperatures. By such experiments, those diode thermometers

which are unstable as a result of construction (contacts, etc.) should be

quickly detected. It is recommended that an investigation of a selection of

such diode thermometers from the various manufacturers be

undertaken.

CALIBRATION REPORT NO RUN870 - 8

MODEL DT-500FP-HRC-7

SENSOR TYPE: SILICON DIODE SERIAL NO. D36312

This temperature sensor has been calibrated against standards

maintained by Lake Shore Cryotronicsf Inc*

All calibrations provided by Lake Shore are based on the 1976

Provisional 0*5K to 30K Temperature Scale (EPT-76) and the

International Practical Temperature Scale of 1968 (IPTS-6S)

for temperatures above 30K* At lower temperatures (below O.bK

a cerium magnesium nitrate magnetic thermometer has been used

in conjunction with NBS superconducting fixed points SRM768 to

generate a' scale*

Each scale is currently maintained on a set of germanium or

platinum resistance standards* as appropriate? which are

routinely checked by intercomparison and periodically

calibrated by the United States National Bureau of Standards

or Great Britain's National Physical Laboratory.

Lake Shore's calibration facility and procedures for diode and

resistance sensor calibrations above 1.2K are maintained

traceable in accord with MIL STD 45662.

11. ABSTRACT (A 200-word or less factual summary of most significant information. If document includes a significant

bibliography or literature survey, mention it here)

An investigation of the stability of 10 silicon diode thermometers upon

normal handling and upon thermal cycling between liquid nitrogen temperatures

and 60 °C was conducted. The diodes underwent 28 thermal cycles and during that

time, only one experienced instabilities equivalent to as small as ±0.045 K. The

other nine diodes had instabilities which ranged from about ±0.09 K to ±0.20 K

12. KEY WORDS (Six to twelve entries ; alphabetical order; capitalize only proper names; and separate key words by semicolons)

Cryogenics; diodes; diode thermometers; silicon diodes; thermal cycling;

thermometry.
