Principle of Zirconia 2 cell Pump Type Oxygen Analyzer
1. Construction and functions (Refer to figure at right)①Heater : Sensing element is heated to approx. 800℃
②Sensing Cell : (1) Set the oxygen concentration of reference oxygen chamber to approx. 100%(2) Measure the oxygen concentration of gas detection chamber.
(Refer to the following for detailed theory of operation.)③Pumping Cell :Set the oxygen concentration of gas detection chamber to 0%.
(Refer to the following for detailed theory of operation.)④Gas Detection Chamber : Gather the exhaust gas through the gas diffusion holes.
⑤Reference Oxygen Chamber : The oxygen concentration is at approx.100% with the reference oxygen
electrical Micro current.
2. Characteristics of the detection section when heated to a high temperature①An electromotive force (EMF) is generated with an induced oxygen ion conduction when gases ofdifferent oxygen concentration are placed between the electrodes.
(Oxygen Battery by Concentration Principle)②By flowing an electrical current are transferred in the opposite direction to the electrical current.
(Oxygen Pumping Effect)
The sensing cell utilizes principles ① and ② , while the pumping cell utilizes principle ②.
3.Principle of the sensing cell
①A minute electrical current flow is applied between the electrodes of the sensing cell.
By flowing electrical current through the electrodes , oxygen in the gas detection chamber is transferredto the reference oxygen chamber and the oxygen concentration of reference oxygen chamber becomesapproximately
100%.
NOTE:As the amount of oxygen transferred from gas detection chamber to the reference
oxygen chamber is extremely small , the oxygen concentration in the gas detection chamber isnotaffected.
②An electromotive force determined by the equation shown below is generated between the electrodesof the sensing cell owing to the difference in oxygen concentrations between gas detection andreference oxygen chambers.
This electromotive force is measured in the sensing cell section and sends a signal to the pumping cellso that this electromotive force will become 350mV(oxygen concentration in the gas detection chamber is 0%).

EMF = About － 53.2 × Log10

Oxygen Concentration in Gas Detection Chamber
Oxygen Concentration in Reference Oxygen Chamber (100)X
450 = -53.2 × log10 100

X = 0.00348ppm≒0%－5－

4.Principle of the pumping cellAn electrical current is applied between the electrodes of the pumping cell so that the oxygen concentrationof the gas detection chamber becomes 0% by receiving a signal from the sensing cell.
Because the oxygen concentration in the exhaust gas is proportional to the electrical current that flowed ,the oxygen concentration in the exhaust gas can be measured by measuring the electrical current.

Inspection after installation
Proper wiring from the transmitter of Model TF Zirconia type O 2 analyzer to the receiver ofModel DTF-101 receiver.

If power is supplied to the wrong wiring, it will cause a sensor

breakage or other serious trouble.
In order to prevent trouble which results from wrong wiring, check the wiring by the following procedure
with the air selected as the measured gas when turning on the power supply for the first time for test
operation and adjustment.
After verifying that the power supply of the receiver is off, check the following.
(1)

Heater wiring check (H+),(H-),(S+),(S-)
Check the followings after confirmed the receiver power is OFF.
• Resistance is measured at terminal block of the receiver between (H+), (H-) and between (S+),(S-).
Standard value: Wiring cable resistance(1 ohm/100 meter for 2 sq.)
• Resistance is measured at terminal block of the receiver between (H+), (H-), and between (S+),(S-).
Standard Value: Wiring cable resistance (1 ohms/100 meter for(2)

2 sq.)

Signal Load Wiring Check(Vs+),(Vs-),(Ip+),(Ip-)
Turn the electrical power to ON by disconnecting the lead wires of (Ip+),(Ip-) at

receiver terminal

block. Warm-up of transmitter is complete in about 3 minutes, so the followings are measured at
the lead wires disconnected at the receiver terminal board.
Take sufficient care to prevent the disconnected line from being short-circuited or grounded.

The EMF between (Vs+) and (Vs-) is measured.
Standard value: 0 to 150mV (Approx. 50mV)The EMF between (Ip+) and (Ip-) is measured.
Standatd value: 0 to 100mV(Approx. omV)
(3)

Heater polarity check
Followings are measured at terminal block of the receiver.
Voltage between (H-) and (H+) Standard value: 5 to 13V(approx. 10V)
Voltage between (S-) and (S+) Standard value: 5 to 13V(approx. 10V)
Potential of (H+) and (S+) must be the same.
Potential of (H-) and (H+) must be the same.

(4)

Signal wiring polarity check
Turn the electrical power to OFF and connect the lead wires(Ip+) and (Ip-) disconnectin inparagraph(2) on the receiver side

－15－

Then turn the electrical power to ON and the followings are measured at transmitter side after
elapsed 3 minutes.
Voltage between (Vs-) and (Vs+): Standard value: 100 to 600mV(approx. 450mV)
Voltage between (Ip-) and (Ip+): Standard value: 0.5 to 1.5V(approx. 1V)(5)

Maintenance inspections and wiring checks during the sensor replacements will be easier when
the cable marking bands are attached on the transmitter and receiver cables at this time after
completed the wiring checks.
Note: The standard values indicated in paragraph(1) through(4) above are those when the sensor
is at an initial condition. Because that value may change with the use, therefore, the wiring
checks must be made using the sensor in an initial condition.

Sensorinspection

Interval

One month

MethodAccording to Item 5-6, apply the gas calibration.
(According to Item 5-3(4), set the calibration method and so on.)Interval

One month

MethodAfter the gas calibration is completed, check the drift value against
the previously calibrated value.
(CAL, DATA MONITOR)
Though it is normally +/-2% F.S./month or less, the sensor may beliable to age if the value is exceeded.

Interval

1 to 6 months (Check if any abnormality is found during gas
calibration.)

MethodThe electromotive force at air point is verified (DISPLAY SELECT)A voltage of about 50mV while in normal operation becomes tothose exceeding 100mV when in error. When such is the case,then the sensor is considered started to degrade due to thepoisoning gas being absorbed at the sensing cell electrode.

Interval

Inferred to be more than 2 years (varies according to theproperties of sampled gas)

Error display
If any error occurs, the error number will be displayed on the 7-segment LED to display the causeof the error. At this time, the function to calculate the concentration is stopped for interruption.
During heater control, it is automatically continued or stopped depending on the content of theerror.
