5.2 Connecting the sensor cables

Terminal assignment of the sensor terminals(® å 7, ä 15).

NOTICE

When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell). The
resulting equalizing currents distort the measurements considerably.

►

The sensors must remain galvanically isolated from one another by connecting each sensor
separately to a transmitter. The transmitter provides sufficient galvanic isolation (> 2 kV AC)
between the input and output.

• The terminals for connecting the signal cable (1+ and 2-) are protected against reverse
polarity.
Conductor cross-section:

•
– Max. 2.5 mm2 for screw terminals
– max. 1.5 mm2 for spring terminals. Min. stripping length of wire 10 mm (0.39 in).

5.4 Shielding and grounding

Optimum electromagnetic compatibility (EMC) can only be guaranteed if the system components
and, in particular, the lines are shielded and the shield forms as complete a cover as possible. A
shield coverage of 90% is ideal.

• To ensure an optimum EMC protective effect when communicating with HART®, connect the
shield as often as possible to the reference ground.

• For reasons of explosion protection, you should refrain from grounding however.

To comply with both requirements, three different types of shielding are possible when
communicating with HART®:

• Shielding at both ends

• Shielding at one end on the feed side with capacitance termination at the field device

• Shielding at one end on the feed side

Experience shows that the best results with regard to EMC are achieved in most cases in
installations with one-sided shielding on the feed side (without capacitance termination at the
field device). Appropriate measures with regard to input wiring must be taken to allow
unrestricted operation when EMC interference is present. These measures have been taken into
account for this device. Operation in the event of disturbance variables as per NAMUR NE21 is

18 Endress+Hauser

thus guaranteed. Where applicable, national installation regulations and guidelines must be
observed during the installation! Where there are large differences in potential between the
individual grounding points, only one point of the shielding is connected directly with the
reference ground. In systems without potential equalization, therefore, cable shielding of fieldbus
systems should only be grounded on one side, for example at the supply unit or at safety barriers.

Grounding point for HART® communication cable shield

NOTICE

If the shielding of the cable is grounded at more than one point in systems without
potential matching, power supply frequency equalizing currents can occur that damage
the signal cable or have a serious effect on signal transmission.

►

In such cases the shielding of the signal cable is to be grounded on only one side, i.e. it must
not be connected to the ground terminal of the housing (terminal head, field housing). The
shield that is not connected should be insulated!

12.4 Accuracy

Response time

The measured value update depends on the type of sensor and connection method and moves
within the following ranges:

Resistance thermometer (RTD) 0.9 to 1.2 s (depends on the connection method 2/3/4-wire)

Thermocouples (TC) 0.7 s

Reference temperature 0.5 s

When recording step responses, it must be taken into account that the times for the
measurement of the second channel and the internal reference measuring point are added to
the specified times where applicable.

Reference conditions • Calibration temperature: +25 °C ±5 K (77 °F ±9 °F)

Supply voltage: 24 V DC

•

• 4-wire circuit for resistance adjustment

Maximum measured error The data concerning the various measured errors are typical values and correspond to a standard

deviation of ±3 s (normal distribution), i.e. 99.8 % of all the measured values achieve the given
values or better values.

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:

Endress+Hauser 43

Technical data

iTEMP® TMT82

• Callendar-Van-Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van-Dusen equation is described as:

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 with the aid of sensor calibration.

Linearization for copper/nickel resistance thermometers (RTD)

•
The polynomial equation for copper/nickel is as follows:

The coefficients A and B 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. The sensor-specific coefficients are then sent to the transmitter.

Sensor transmitter matching using one of the methods explained above significantly improves the
temperature measurement accuracy of the entire system. This is because the transmitter uses the
specific data pertaining to the connected sensor to calculate the measured temperature, instead of
using the standardized sensor curve data.

Maximum process temperature: 100 °C (212 °F)

Measured resistance value: 138.5 W (IEC 60751) at maximum process temperature
Typical temperature drift in W: (0.001 % of 138.5 W) * 10 = 0.01385 W
Conversion to Kelvin: 0.01385 W / 0.385 W/K = 0.04 K (0.072 °F)

Corrosion monitoring

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 is affected. Corrosion
monitoring is only possible for RTDs with a 4-wire connection and thermocouples.

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 mode can be used to verify the correctness of
the measured values and for mutual monitoring of the connected sensors. The drift/difference

4. Enter the reference temperature for the value at the start of the measuring range for the Sensor trimming lower

This parameter can only be selected if the Burst mode option is enabled.

Use this function to assign a measured variable to slots 0 to 3.

This assignment is only relevant for the burst mode. The measured variables are assigned to
the 4 HART variables (PV, SV, TV, QV) in the HART output (® ä 92) menu.

• Sensor 1 (measured value)

•

Sensor 2 (measured value)

• Device temperature

• Average of the two measured values: 0.5 x (SV1+SV2)

• Difference between sensor 1 and sensor 2: SV1-SV2

• Sensor 1 (backup sensor 2): If sensor 1 fails, the value of sensor 2 automatically becomes the
primary HART® value (PV): sensor 1 (OR sensor 2)

• Sensor switching: If the value exceeds the configured threshold value T for sensor 1, the
measured value of sensor 2 becomes the primary HART® value (PV). The system switches back
to sensor 1 when the measured value of sensor 1 is at least 2 K below T: sensor 1 (sensor 2, if
sensor 1 > T)

The threshold value can be set with the Sensor switch set point parameter. With
temperature-dependent switching, it is possible to combine 2 sensors that offer advantages in
different temperature ranges.

Average: 0.5 x (SV1+SV2) with backup (measured value of sensor 1 or sensor 2 in the event of a
sensor error in the other sensor)
