Request Information

The Adjustable Transmitter is a device used in an analog current loop to test a 4-20mA Input, calibrate or demo equipment. The 4-20mA Current Simulator is a current simulator/loop simulator, which simulates an analog field device such as a Pressure Transducer or Temperature Transmitter. When placed in the analog current loop, the loop powered 4-20mA simulator regulates the current in the loop to the setting on the knob from 4 to 20 mA. When a more precise setting is required, place an ammeter in the current loop to display the loop current.
