An unshielded installation cable suffices if only the analog signal is used. The use ofshielded cables is recommended for increased EMC interference. As of a sensor cable
length of 30 m (98.4 ft), a shielded cable must be used for a head transmitter in the field
mount housing with a separate terminal compartment and for the DIN rail transmitter.
A shielded cable is recommended for HART communication. Observe grounding concept of
the plant. A minimum load of 250 Ω is required in the signal circuit in order to operate the
HART transmitter via the HART protocol (terminals 1 and 2).

points is mandatory following installation in the field or servicing in order to ensure that
IP67 protection is maintained:• The transmitter must be mounted in a terminal head with the appropriate degree ofprotection.
• The housing seals must be clean and undamaged when inserted into the sealing groove.
The seals must be dried, cleaned or replaced if necessary.
• The connecting cables used must have the specified external diameter (e.g. M20x1.5,
cable diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  13,  24
• The cables must loop down before they enter the cable glands ("water trap"). This meansthat any moisture that may form cannot enter the gland. Install the device in such a waythat the cable glands are not facing upwards. →  13,  24
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

Supported HART commands
The HART protocol enables the transfer of measuring data and device data between
the HART master and the field device for configuration and diagnostics purposes.
HART masters such as the handheld terminal or PC-based operating programs (e.g.
FieldCare) need device description files (DD, DTM) which are used to access all theinformation in a HART device. This information is transmitted exclusively via"commands".

There are three different types of command• Universal commands:
All HART devices support and use universal commands. These are associated with thefollowing functionalities for example:• Recognition of HART devices• Reading digital measured values• Common practice commands:
Common practice commands offer functions which are supported and can be executed bymany but not all field devices.
• Device-specific commands:
These commands allow access to device-specific functions which are not HART standard.
Such commands access individual field device information, among other things.

Sensor adjustment

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:• Callendar van Dusen coefficients (Pt100 resistance thermometer)
The Callendar van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter inorder 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 isrequired, the coefficients for each sensor can be determined specifically with the aid ofsensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistancethermometers (RTD). The exact values of the coefficients derive from the calibration
data and are specific to each sensor. The sensor-specific coefficients are then sent to thetransmitter.
Sensor-transmitter matching using one of the methods mentioned above significantly
improves the temperature measurement accuracy of the entire system. This is because thetransmitter uses the specific data pertaining to the connected sensor to calculate themeasured temperature, instead of using the standardized sensor curve data.
1-point adjustment (offset)
Shifts the sensor value
2-point adjustment (sensor trimming)
Correction (slope and offset) of the measured sensor value at transmitter input

Current output adjustment

Correction of 4 or 20 mA current output value (not possible in SIL mode)

Backup function
If the Sensor 1 (backup sensor 2) option or Average: 0.5 x (SV1+SV2) with backup isselected in the Assign current output (PV) parameter, the corresponding backup functionis active.
If Sensor 1 (backup sensor 2) is selected, the transmitter automatically switches to sensor
2 as the primary measured value in the event of a failure of sensor 1. The measured valueof sensor 2 is used as the PV. The 4 to 20 mA signal is not interrupted. The status for thefaulty sensor is output via HART. If a display is connected, a diagnostic message isdisplayed here.
If Average: 0.5 x (SV1+SV2) with backup is selected, 3 scenarios can occur:• If sensor 1 fails, the average value corresponds to the measured value of sensor 2, the
4 to 20 mA signal is not interrupted and a diagnosis is output via HART.
• If sensor 2 fails, the average value corresponds to the measured value of sensor 1, the
4 to 20 mA signal is not interrupted and a diagnosis is output via HART.
• If both sensors fail simultaneously, the transmitter follows the configured failure mode
and a diagnosis is output via HART.
The Reset sensor backup parameter defines how the transmitter acts after the sensor
error has been rectified.

Operating menu and parameter description

iTEMP TMT82

Sensor connection cable corrosion can lead to false measured value readings. Therefore
the unit offers the possibility of recognizing any corrosion before a measured value isaffected. Corrosion monitoring is only possible for RTDs with a 4-wire connection andthermocouples.
Drift/difference mode
If two sensors are connected and the measured values differ by a specified value, a status
signal is generated as a diagnostic event. The drift/difference monitoring function can beused to verify the correctness of the measured values and for mutual monitoring of theconnected sensors. Drift/difference monitoring is enabled with the Drift/difference modeparameter. A distinction is made between two specific modes. If the In band option is
selected (ISV1-SV2I < drift/difference set point), a status message is issued if the value
drops below the set point, or if the value exceeds the set point if the Out band (drift)
option is selected (ISV1-SV2I > drift/difference set point).
Procedure for configuring the drift/difference mode
1. Start↓
2. For drift/difference monitoring, select Out band for drift detection and In band for difference monitoring.
↓
3. Set the alarm category for drift/difference monitoring to Out of specification (S), Maintenance required(M) or Failure (F) as required.

Sensor error adjustment (sensor trimming)
Sensor trimming is used to adapt the actual sensor signal to the linearization of theselected sensor type stored in the transmitter. Compared to sensor transmitter matching,
sensor trimming only takes place at the start and end value and does not achieve the samelevel of accuracy.
Sensor trimming does not adapt the measuring range. It is used to adapt the sensor
signal to the linearization stored in the transmitter.
Procedure
1. Start↓
2. Set the Sensor trimming parameter to the Customer-specific setting.
↓
3. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature. A
temperature which is close to the set start of the measuring range is recommended.
↓
4. Enter the reference temperature for the value at the start of the measuring range for the Sensor trimming
lower value parameter. Based on the difference between the specified reference temperature and thetemperature actually measured at the input, the transmitter internally calculates a correction factor which is
now used to linearize the input signal.
↓
5. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature
close to the set end of the measuring range.
