The Importance of Grounding Pressure Transmitters and Shielded Wiring

Pressure Transmitter /

1. Grounding of the Pressure TransmitterGrounding of a pressure transmitter refers to the connection of its metal housing to the earth via a conductor. This ensures that the transmitter’s metal housing and components are at the same electrical potential as the earth. The primary purpose of grounding is to safely redirect leakage currents caused by […]
