TMT84
The temperature transmitter is a two-wire device with two measuring inputs. Using PROFIBUS® PA,
the device transfers converted signals from resistance thermometers and thermocouples in addition to
other resistance and millivolt signals. The device is powered via the PROFIBUS
installed as an intrinsically safe apparatus in zone 1 hazardous areas. The device is used for
instrumentation purposes in the terminal head form B as per DIN EN 50446. Data transfer takes place
via 4 analog input (AI) function blocks:
Sensor diagnosis functions
Sensor diagnoses such as cable open circuit, short-circuit, cable corrosion, wiring error and device
hardware error are supported. In addition, the work area of the sensor and the ambient temperature
are monitored.
2-channel functions
These functions increase the reliability and availability of the process values:
• Sensor backup switches to the second sensor if the primary sensor fails.
• Drift warning or alarm if the deviation between sensor 1 and sensor 2 is less than or greater than a
predefined limit value.
• Temperature-dependent switching between sensors which have advantages in different ranges.
Compatibility mode
For a easy replacement of the previous model iTEMP TMT184 with the TMT84 a compatibility mode
is available. The switching between the standard mode and compatibility mode in the iTEMP TMT84
is done automatically during the connection establishment of the cyclic communication.
The Following points have to receive attention:
•Only PROFIBUS
• Only 1-channel operation possible.
• The diagnostics and status handling is equal to the previous model TMT184.
• The previous model TMT184 software locking is not available.

If the TMT84 operates in the compatibily mode, the device is identifying with the manufacturer specific ID-no.: 1523 (Hex) - TMT184 in the cyclic data exchange.
Brief description of the blocksPhysical Block
The Physical Block contains all the data that clearly identify and characterize the device. It is like an
electronicdevice nameplate. In addition to parameters that are needed to operate the device on the
fieldbus, the Physical Block makes other information available such as the order code, device ID,
hardware revision, software revision, device release, etc. Furthermore the display settings can be
configured via the Physical Block.
Transducer Block "Sensor 1" and "Sensor 2"
The Transducer Blocks of the transmitter contain all the measurement-related and device-specific
parameters that are relevant for measuring the input variables.
Analog Input (AI)
In the AI function block, the process variables from the Transducer Blocks are prepared for subsequent
automation functions in the control system (e.g. scaling, limit value processing).

must be linearized. To improve temperature measurement accuracy significantly, the device enables
the use of two methods:
• Callendar-Van Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van Dusen equation is described as:
-100
3
The coefficients A, B and C are used to match the sensor (platinum) and transmitter in order to
improve 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 for
each sensor can be determined specifically by means of sensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equations for nickel are described as:
-100
3
The equations for copper, subject to temperature, are described as:
T = -50 °C to 200 °C (-58 °F to 392 °F)
T = -180 °C to -50 °C (-292 °F to -58 °F)
These coefficients A, B and C 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 each sensor.
Sensor transmitter matching using one of the above-named methods significantly improves the
temperature measurement accuracy of the entire system. This is due to the fact that to calculate the
temperature measured, the transmitter uses the specific data pertaining to the connected sensor
instead of using the standardized sensor curve data.

There are no display or operating elements present at the transmitter.
Optional the plug-on display TID10 can be used in connection with the transmitter. It will display
information regarding the actual measured value and the measurement point identification. In the
event of a fault in the measurement chain this will be displayed in inverse color showing the channel
ident and diagnostics code. DIP-switches can be found on the rear of the display. This enables the
