Resistance Transmitter BRT283

The BRT283 is a isolating transmitter that measures the resistance of a probe or sensor.

Description

The BRT283 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. The output signal level is indicated by a green LED on front giving a clear indication of module function. Reverse or direct action are factory configured. Special requirements for input/output response time variation can be accommodated by optional the “output ramp” option or the three standard link selectable response times
