Potential Transmitter

Potential Transmitter

Potential transmitter is designed to turn the ground potential isolation of buried metal pipes into standard 4~20mA industrial signal output. It is equipped with standard communication data transmission interface RS-485, which is convenient for the central control system to collect and process data of the cathode-protection system. The ground potential can be displayed on the LCD screen in real time, and has functions of lightning protection and lightning counter.

Description

Product Introduction

 

          Potential transmitter is an industrial device for measuring and transmitting resistance, voltage, or position signals that converts analog signals from a sensor into standard industrial signals for remote transmission to a control system. Potential transmitters are the "bridge" between mechanical sensors and control systems in industrial automation, suitable for scenarios requiring high-precision resistance/voltage signal conversion.
