4. Operation

Once installed and wired correctly, the transducer will automatically convert the temperature reading from the connected sensor into a proportional 4-20mA current signal. This signal can then be transmitted to a control system, PLC, or display unit.

4.1 Range Adjustment

The transducer features an adjustable range. This can typically be configured via a PC or a hand controller, allowing calibration to specific temperature ranges as required by the application. For thermocouple inputs, automatic cold-end compensation ensures accurate readings.
