Pro-Range PR18-A11 Pressure Transducer 0-0.5 MPa, 4-20mA Output, G1/4" Thread

The PR18-A11 operates on a standard two-wire 4-20mA current loop. It requires an external DC power supply, typically between 12V and 24V, connected in series with the loop and the readout device (PLC, display, or data logger). The sensor draws its operating current from this loop, with the 4-20mA signal representing the measured pressure.

Yes, the stainless steel sensing element and G1/4" threaded port are compatible with both non-corrosive gases and liquids. Ensure the media is compatible with 304 stainless steel. For aggressive media, verify material compatibility or inquire about alternative diaphragm materials from the manufacturer.

Installation involves screwing the G1/4" male thread into a corresponding female port on your pressure line using a suitable sealant or washer. For wiring, connect the positive (+) loop supply to one transducer wire, and connect the other transducer wire to the positive input of your 4-20mA receiver. The receiver's negative input is then connected back to the negative (-) of the loop power supply to complete the circuit.

This industrial-grade transducer offers high accuracy, typically within ±0.5% to ±1.0% of full scale, depending on calibration. It is designed for long-term stability, meaning the output signal will remain consistent over time and through repeated pressure cycles, which is critical for reliable process control and monitoring.
