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.

Optional 2-channel functions
These functions increase the reliability and availability of the process values:
• Sensor backup switches to redundant sensor if primary sensor fails
• Temperature dependent switching between sensors, which have advantages in different ranges
• Drift alert or alarm if sensor 1 and 2 deviate from one another

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.
