Resistance Transmitter - RT283

Resistance Transmitter - RT283

The RT283 is a isolating transmitter that measures the resistance of a probe or sensor.

A constant current is applied to the input device and a change of resistance value causes the voltage to change. The precision current source is adjustable by a 15-turn potentiometer located on the input card.

The measured input is then scaled by a isolating transmitter with a link selectable output providing true 3-way galvanic isolation up to 2000V rms.

A wide range ac/dc power supply powers the input and the output circuit with three way power/input/output isolation.

Final calibration is trimmed using the front accessible ZERO and SPAN 15-turn trim adjustments
