CS Position Transmitter

A 4-20 mA analog current transmitter featuring the latest solid-state design for communicating with any 2-wire indicating device. Small enough to be used in a variety of enclosures, it functions with one of the lowest operating voltages in the industry.

Features & Benefits:

  • Precision analog position transmitter.
  • Operates with any voltage from 6.5 to 33 volts DC.
  • Non-interacting zero and span potentiometers easily adjust the desired settings.
  • Easy set up, non-interactive adjustment.
  • Clockwise and counter clockwise rotation easily accommodated.
  • Reverse polarity and transient protected.
  • Accommodates long cable runs and multiple receivers.
  • Encapsulation of electrical components improves performance in harsh environments.
  • Available with proximity sensors or mechanical switches.
  • CS transmitter can be used with standard analog input module supplying a 4-20 mA retransmission for continuous monitoring of valve travel.
