Pro-Range PR15C-PAS-020K Digital Pressure Sensor 0-20 kPa, 4-20mA Output, G1/4 Thread, 1m Cable

This is a two-wire loop-powered device. Connect the positive (+) supply wire (10-32VDC) to the sensor's red cable lead. Connect the sensor's black cable lead to the positive input of your 4-20mA receiver (PLC, meter, or data logger). Finally, connect the negative of your receiver back to the negative (-) of your DC power supply to complete the current loop.

No, this sensor's 4-20mA output is not directly compatible with 5V logic inputs. You require an external 10-32VDC power supply for the sensor loop and a separate 250-ohm precision resistor (or a dedicated 4-20mA receiver shield) to convert the current signal into a 1-5V voltage that can be read by your microcontroller's ADC.

G1/4 is a British Standard Pipe Parallel (BSPP) thread with a 55-degree flank angle and a sealing washer or O-ring. NPT (National Pipe Tapered) is an American standard with a 60-degree flank angle that seals via thread taper. They are not directly interchangeable. Ensure your system's mating port matches the G1/4 BSPP thread of this sensor or use an appropriate adapter.

The 1-meter shielded cable is integral to the sensor housing. For longer runs, you can splice and extend the cable using proper waterproof connectors and shielded cable to maintain signal integrity. The 4-20mA current output is inherently resistant to voltage drop and noise over extended distances.
