5.5.2 Sensors
Designation of connection terminals
Resistance thermometer (RTD) and resistance sensor
The connection of a resistance thermometer (e.g. per DIN EN 60751) in a 2-, 3- or 4-wire
connection is possible or the connection of a potentiometer in a 3-wire connection.
The sensor input of the transmitter must be configured in accordance with the sensor
connection type actually used, otherwise a complete use of the possibilities of connection
cable compensation is not possible and may potentially cause additional measuring errors.
For the safety-relevant maximum values for the connection of the voltage
supply and the sensors, see chapter 10 “Specifications”.
