Pro-Range PR12-P145B Pressure Transducer 0-0.2 MPa, 0.5-4.5V Output, G1/4" Thread

The transducer typically operates on a 5V DC supply, as the output is ratiometric. This means the 0.5–4.5V output signal scales linearly with both the applied pressure and the supply voltage. Always verify the exact excitation voltage requirements in the product datasheet for optimal accuracy.

Connect the transducer's output wire to an analog input pin on your microcontroller (e.g., Arduino) or PLC analog module. The 0.5–4.5V signal falls within the standard 0-5V ADC range, making interfacing straightforward. Ensure you provide a stable 5V supply to the sensor and read the analog value, then map it to the 0–0.2 MPa pressure scale in your code or logic.

Yes, the PR12-P145B is designed to measure pressure of compatible, non-corrosive liquids and gases. The stainless steel pressure port and sensing diaphragm are suitable for common media like air, water, and hydraulic oils. For aggressive chemicals or media, confirm material compatibility with the manufacturer's specifications.

The transducer is factory calibrated, providing typical accuracy within ±0.5% of full scale (FS). For most applications, no user calibration is needed. For critical high-precision applications, a two-point calibration (zero and full-scale pressure) can be performed using the known 0.5V and 4.5V output endpoints to refine the measurement.
