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.
Most drawings are supplied in PDF format. Portable Document Format is used to present documents in a manner independent of application software, hardware, and operating systems.
Lead Time for a Traditional Product
Traditional products usually contain the same functionally as standard and premier products but have a different connection, part number or specifications. Traditional products are still available as a service to our customers that have them specified in their plants. Delivery is typically 7 days.
