5.2 Connecting the sensor cables

Terminal assignment of the sensor terminals (® å 5, ä 13).

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 measurement 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 following connection combinations are possible when both sensor inputs are assigned:

Cable specification

• A normal device cable suffices if only the analog signal is used.

• A shielded cable is recommended for HART® communication. Take the plant grounding concept into consideration.

Please also observe the general procedure on (® ä 13).

Terminals for HART® -protocol and power supply

Shielded signal cable (recommended for HART® protocol)

• 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

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 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!

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:

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.

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.

Example of calculating the measured error with ambient temperature drift:

Input temperature drift DJ = 10 K (18 °F), Pt100, measuring range 0 to 100 °C (32 to 212 °F).

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 mode is enabled with the Drift/difference mode parameter. 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 output 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.

4. Set the set point for drift/difference monitoring to the desired value.

Adjustment of the analog output (4 and 20 mA current trimming)

Current trimming is used to compensate the analog output (D/A conversion). Here, the output current of the transmitter can be adapted so that it suits the value expected at the higher-order system.

NOTICE

Current trimming does not affect the digital HART® value. This can cause the measured value shown on the plug-in display to differ from the value displayed in the higherorder system.

►

The digital measured values can be adapted with the sensor trimming parameter in the menu Expert ® Sensor ® Sensor trimming.

Procedure

1. Start

2. Install an accurate amperemeter (more accurate than the transmitter) in the current loop.

3. Switch on current output simulation and set the simulation value to 4 mA.

4. Measure the loop current with the amperemeter and make a note of the value.

5. Set the simulation value to 20 mA.

6. Measure the loop current with the amperemeter and make a note of the value.

Sensor error adjustment (sensor trimming)

Sensor trimming is used to adapt the actual sensor signal to the linearization of the selected 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 same level of accuracy.

Operating menu and parameter description T82

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 User trim settings setting.

3. Using a water/oil bath or a furnace, 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 predefined reference temperature and the temperature 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 or furnace, bring the sensor connected to the transmitter to a known and stable temperature close to the set end of the measuring range.

6. Enter the reference temperature for the value at the end of the measuring range for the Sensor trimming upper value parameter.
