Pro-Range PR15C-PAS-040 Digital Pressure Sensor 0-4 MPa, 4-20mA Output, G1/4 Thread, 1m Cable

This is a two-wire loop-powered sensor. Connect the positive supply wire (10-32 VDC) to the sensor's positive terminal, and connect the sensor's negative terminal to the positive input of your 4-20mA receiver (PLC, meter, or data logger). The receiver's negative input is then connected to the power supply ground, completing the loop. The current signal is proportional to the pressure.

No, this sensor outputs a 4-20mA current signal and requires a 10-32 VDC power supply. To interface with a 5V microcontroller like Arduino, you will need an external 24V power supply for the sensor and a separate 250-ohm precision resistor to convert the 4-20mA signal into a 1-5V voltage readable by the Arduino's analog input.

The rated working pressure range is 0 to 4 MPa. Exceeding this range, especially significantly beyond 4 MPa, may cause permanent damage or calibration shift. For safety, it is recommended to include a pressure relief valve in your system. The sensor may have a burst pressure rating higher than 4 MPa; consult the manufacturer's datasheet for specific overpressure limits.

Yes, the Pro-Range series is customizable. Common alternatives include G1/2, M20x1.5 threads, and RS485 Modbus digital output. Pressure ranges can also be specified up to 25 MPa. For custom configurations, you must contact the supplier or manufacturer directly with your specific requirements.
