Function and system design
Measuring principle Electronic monitoring, conversion and display of input signals in industrial temperature measurement.
Measuring system
T09-TMT162ZZ-14-00-xx-yy-002
Examples of applications
mTwo sensors with measuring input (RTD or TC) in remote installation with the advantages: drift alert, sensor backup
function and temperature dependent sensor switch
n1 x RTD/TC or 2 x RTD/TC as redundancy
oTemperature field transmitter in combination with a sensing element, insert and thermowell as compact thermometer
The iTEMP®temperature field transmitter TMT162 is a two-wire transmitter with analog output or fieldbus
protocol, two (optional) measuring inputs for resistance thermometers and resistance transmitters in 2-wire, 3-
wire or 4-wire connection (for one resistance measuring input), thermocouples and voltage transmitters. The
LC display shows the current measured value digitally and as a bar graph with an indicator for alarms.
Corrosion detection
Corrosion of the sensor connections can lead to corruption of the measured value. The field transmitter offers
the option of detecting corrosion on thermocouples and resistance thermometers with a 4-wire connection
before measured value corruption occurs. The transmitter avoids false measured readings and is also able to
indicate a warning on the display as well as through HART®or Fieldbus protocol when wire resistance exceeds
reasonable values.
Low voltage detection for HART®communication
The low voltage detection prevents the device from continuously outputting an incorrect analog output value
(i.e. due to damaged or incorrect power supply or due to a damaged signal cable). If the required supply voltage
is undershot, the analog output value drops < 3.6 mA for approx. 3 s. An error message appears on the display.
Afterwards the device tries to output the normal analog output value again. If the supply voltage is still too low,
the analog output value drops again to < 3.6 mA.

1) Significant measuring error increase for temperature lower than 300 °C (572 °F).
2) When operating conditions are based on a large temperature range, the TMT162 offers the ability to split the range. For example, a Type S or R thermocouple
can be used for the low range and a Type B can be used for the upper range. The TMT162 is then programmed to switch at a predetermined temperature.
This allows for utilization of the best performance from each individual thermocouple and provides 1 output that represents the process temperature. Note:
the dual sensor option must be included in the order code for the HART®protocol. Two sensor inputs are already provided as standard if the FF and PA
protocol are selected.
3) Basic requirements NE89: detection of increased sensor resistance (e.g. corrosion of contacts or wires) of TC or RTD/4-wire.

Sensor transmitter matching
Resistance thermometers have high linearity. However, every sensor has an individual temperature resistance
characteristic curve. This characteristic curve must be described as accurately as possible in order to achieve a
high level of accuracy in the linearization of the measured values in the transmitter. The TMT162 allows you
to utilize two methods:
• Customer-specific linearization
Using PC configuration software or the HART®handheld, the device can be programmed with sensor-
specific curve data. Once the sensor-specific data has been entered, the device utilizes this to generate a
custom curve. Readwin®2000 software supports by calculating sensor-specific curves.
• Callendar - Van Dusen coefficients
The Callendar - Van Dusen equation is described as:
where A, B and C are constants, commonly referred to as Callendar - Van Dusen coefficients. The precise
values of A, B and C are derived from the calibration data and are specific to each RTD sensor.
The process involves programming the device with curve data for a specific RTD, instead of using the standard
curve.
Sensor transmitter matching using any of the above methods substantially improves the temperature
measurement accuracy of the entire system. This is as a result of the transmitter using the sensor’s actual
resistance vs. temperature curve data instead of the ideal curve data.

CE Electromagnetic Compatibility Compliance
EMC meets all relevant requirements listed under EN 61326 Series and NAMUR NE21. Details as per
declaration of conformity.
This recommendation is a uniform and practical way of determining whether the devices used in laboratories
and process control are immune to interference with an objective to increase its functional safety.
