2-Wire Panel Rail Mount Universal Temperature/Process Transmitters

Input and Output Connection Drawings | Specifications | How to Order

Temperature transmitters are used for a variety of reasons. The use of temperature transmitters can eliminate the need for long costly runs of thermocouple wire vs. less expensive copper signal wire. When the environment is electrically noisy, sending a 4-20 mA signal to the control room reduces the chance of error.
The Tempco ETR Series of 2-wire transmitters offers both isolated and non-isolated versions. They are designed to fit directly on a standard 35mm DIN Rail.
