Wiring the sensor with voltage or current output Wiring the sensor with voltage or current output Wiring the sensor with voltage or current output Wiring the sensor with voltage or current output
Sensor connection with voltage or current output and power supply directly from the controller. The power supply capacity (maximum current) of the
controller must be evaluated. For distances > 10 metres, the 4-20 mA current connection should be used, to avoid measurement errors due to the drop
in the reference M (G0). Sensor connection with separate power supply via transformer, used to avoid measurement errors due to current on reference
M(G0) connection or for power supply problems on G0 with earth connection.

Wiring the sensor to the instrument with NTC resistive output
h NTC resistive output h NTC resistive output
h NTC resistive output
Sensor connection with NTC resistive output: the two signals must be connected directly to the terminals on the instrument,
Do not use M(G0) as the common for the connection of NTC resistive sensor.
