… Shielding of the sensor connecting cable 

 

Additional examples for shielding / grounding 

Insulated sensor measuring inset (thermocouple, mV, RTD, Ohm), transmitter housing grounded 

The shielding of the sensor connection cable is grounded via the grounded transmitter housing. This shielding is insulated from the 
sensor. 
The shielding of the power supply cable is grounded at the supply isolator / DCS input directly This shielding is insulated from the 
transmitter housing. 
The shielding of the power supply cable and the shielding of sensor connection cable must not be connected to one another. Make 
sure that the shielding is not connected to ground anywhere else.
