Application examples
Two sensors with measuring input (RTD or TC) in remote installation with the following advantages: drift
warning, sensor backup function and temperature-dependent sensor switching
1 x RTD/TC or 2 x RTD/TC for redundancy

The iTEMP temperature field transmitter TMT162 is a two-wire transmitter with a PROFIBUS® PA
or FOUNDATION Fieldbus™ protocol, two (optional) measuring inputs for resistance thermometers
and resistance transmitters in 2-, 3- or 4-wire connection (for a resistance measuring input),thermocouples and voltage transmitters. The LC display shows the current measured value digitallyand as a bar graph and also indicates the current status of the device.

Standard diagnostic functions• Cable open circuit, short-circuit• Incorrect wiring• Internal device errors• Overrange/underrange detection• Ambient temperature out-of-range detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings. The fieldtransmitter offers the possibility of detecting corrosion on thermocouples and resistancethermometers with a 4-wire connection before measured value corruption occurs. The transmitter
prevents incorrect readings of measured values and can issue a warning on the display as well as
through the fieldbus protocol if wire resistance values exceed plausible limits.
Optional dual input functions
These functions increase the reliability and availability of the process values:• Sensor backup : If sensor 1 fails, the output signal is switched without interruption to themeasured value of sensor 2.
• Temperature-dependent sensor switching: The measured value is recorded by sensor 1 or 2
depending on the process temperature.
• Sensor drift detection: If both measured values of sensor 1 and 2 deviate from a specified value, adrift warning or alarm is output.

When operating conditions are based on a large temperature range, the transmitter offers you the ability to split the range. For example, a TypeS or R thermocouple can be used for the lower range and a Type B can be used for the upper range. The transmitter is then programmed by theend operator to switch at a predefined temperature. This allows for utilization of the best performance from each individual thermocouple andprovides 1 output that represents the process temperature.
High measuring uncertainty for temperatures below 300 °C (572 °F)
Basic requirement of NE89: detection of increased wire resistance (e.g. corrosion of contacts and wires) of TC or RTD/4-wire. Warning exceeding ambient temperature.

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:• Customized linearization
The transmitter can be programmed with sensor-specific curve data with the PC configuration
software. As soon as the sensor-specific data have been entered, the transmitter uses these to
create a customized curve.
• Callendar-Van-Dusen coefficients
The Callendar-Van-Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
where A, B and C are constant. They are commonly referred as Callendar-Van-Dusen coefficients.
The precise values of A, B and C are derived from the calibration data for the RTD and are specificfor each RTD sensor. The process involves programming the transmitter with the curve data for acertain RTD instead of using a standardized curve.
Sensor transmitter matching using one of the methods explained above significantly improves thetemperature measurement accuracy of the entire system. This is a result of the transmitter using
the sensor’s actual resistance vs. temperature curve data instead of the ideal curve data.

Operability
Operating concept

There are different options available for configuring and commissioning the device:• Configuration programs
Device-specific parameters are configured and set via the fieldbus interface. Special configurationand operating programs are available from various manufacturers for this purpose.
• Miniature switch (DIP switch) for diverse hardware settings
You can perform the following hardware settings for the fieldbus interface (PROFIBUS® PA and
FOUNDATION Fieldbus™) using miniature switches (DIP switches) on the electronics module:• Enabling/disabling of simulation mode (FOUNDATION Fieldbus™)• Switching the hardware write protection on/off• Configuration of device address (PROFIBUS® PA)
