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.

PA-Profile 3.0 is supported.

Sensor transmitter matching RTD sensors are one of the most linear temperature measuring elements. Nevertheless, the output

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

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

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.

Display and operating elements

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 hardware set-up such as the PROFIBUS

Pluggable display TID10

If the transmitter is installed in a field housing and used with a display, a housing with glas window needs to be used.
