or DIN rail transmitter
Installed head transmitter - 1 x RTD/TC wired directly

Endress+Hauser offers a comprehensive range of industrial thermometers with resistance sensors or
thermocouples.
When combined with the temperature transmitter, these components form a complete measuring
point for a wide range of applications in the industrial sector.
The temperature transmitter is a 2-wire device with one measuring input and one analog output.
The device not only transmits converted signals from resistance thermometers and thermocouples, italso transmits resistance and voltage signals using HART communication and as a 4 to 20 mA
current signal. It can be installed as an intrinsically safe apparatus in hazardous areas and is used for
instrumentation purposes in the terminal head form B (flat face) as per DIN EN 50446 or as a DIN
rail device for installation in the cabinet on a TH35 mounting rail as per EN 60715.

Standard diagnostic functions• Cable open-circuit, short-circuit of sensor wires• Incorrect wiring• Internal device errors• Overrange/underrange detection• Device temperature overrange/underrange detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings. The
transmitter makes it possible to detect corrosion of the thermocouples and mV transmitters, as well
as resistance thermometers and ohmmeters with 4-wire connection, before a measured value iscorrupted. The transmitter prevents incorrect measured values from being read out and can issue awarning via the HART protocol if conductor resistance values exceed plausible limits.
Low voltage detection
The low voltage detection function prevents the device from continuously transmitting an incorrect
analog output value (caused by an incorrect or damaged power supply system or a damaged signal
cable). If the supply voltage drops below the required value, the analog output value drops to < 3.6
mA for approx. 5 s. The device then tries to output the normal analog output value again. If the
supply voltage is still too low, this process is repeated cyclically.
Diagnostics simulation
Device diagnostics can be simulated. The following items are set during such simulations:• Measured value status• Current diagnostics information• Status bit of HART command 48• Current output value as per simulated diagnostics
This simulation makes it possible to check that all higher-level systems respond as expected.

If only the analog signal is used, an unshielded installation cable is sufficient. In case of increased
EMC influences, the use of shielded cables is recommended. As of a sensor cable length of
30 m (98.4 ft)30 m (98.4 ft), a shielded cable must be used for the DIN rail transmitter.
A shielded cable is recommended for HART communication. Observe grounding concept of the plant.
A minimum load of 250 Ω is required in the signal circuit in order to operate the HART transmitter
via the HART protocol (terminals 1 and 2).
In the case of a thermocouple measurement (TC), a 2-wire RTD can be connected to measure thereference junction temperature. This is connected to terminals 4 and 6.

Sensor-transmitter matching
RTD sensors are one of the most linear temperature measuring elements. Nevertheless, the output
must be linearized. To significantly improve temperature measurement accuracy, the device allows
the use of two methods:

Endress+Hauser

iTEMP TMT72• Callendar van Dusen coefficients (Pt100 resistance thermometer)
The Callendar van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter in order toimprove the accuracy of the measuring system. The coefficients for a standard sensor are specified
in IEC 751. If no standard sensor is available or if greater accuracy is required, the coefficients foreach sensor can be determined specifically with the aid of sensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistance thermometers(RTD). The exact values of the coefficients derive from the calibration data and are specific to eachsensor. The sensor-specific coefficients are then sent to the transmitter.
Sensor-transmitter matching using one of the methods mentioned above significantly improves thetemperature measurement accuracy of the entire system. This is because the transmitter uses the
specific data pertaining to the connected sensor to calculate the measured temperature, instead ofusing the standardized sensor curve data.

Orientation
When DIN rail transmitters are used with a thermocouple/mV measurement, increased
measurement deviation may occur depending on the installation situation and ambient conditions. If
the transmitter is mounted on the DIN rail without any adjacent devices, this may result in deviationsof ±1.3 °C. If the transmitter is mounted in series between other DIN rail devices (reference
condition: 24 V, 12 mA), deviations of max. +2.9 °C may occur.

Operability
Onsite operation

Head transmitter
The head transmitter has no display or operating elements. There is the option of using theattachable measured value display TID10 together with the head transmitter. The display provides
plain-text information on the current measured value and the measuring point identification. An
optional bar graph is also used. In the event of a fault in the measuring chain, this will be displayed
in inverse color showing the channel ident and error number. DIP switches can be found on the rearof the display. These enable hardware settings to be made e.g. write protection.

Technical Information TI01043K
Advanced Data Manager Memograph M
The Advanced Data Manager Memograph M is a flexible and powerful system for organizing process
values. Optional HART input cards are available, each having 4 inputs (4/8/12/16/20), with highly
accurate process values from the HART devices directly connected for the purpose of calculation anddata logging. The measured process values are clearly presented on the display and logged safely,
monitored for limit values and analyzed. Via common communication protocols, the measured andcalculated values can be easily communicated to higher-level systems or individual plant modules
can be interconnected.
