Pro-Range PR15C-PAS-100K Digital Pressure Sensor 0-100 kPa, 4-20mA Output, G1/4 Thread, 1m Cable

This is a two-wire, loop-powered sensor. Connect the positive (red) wire of the integrated cable to your DC power supply (10-32V). Connect the negative (black) wire to the positive input of your 4-20mA receiver (PLC analog input, data logger, or display). The sensor draws its operating current from this loop, and the measured pressure modulates the current between 4mA (0 kPa) and 20mA (100 kPa).

No, the PR15C-PAS-100K is a gauge pressure sensor with a range of 0 to 100 kPa positive pressure. It measures pressure relative to atmospheric pressure. For vacuum or compound pressure measurements, a different sensor model with a range spanning negative values (e.g., -100 to 100 kPa) would be required.

G1/4 is a British Standard Parallel Pipe thread (BSPP). It is not directly compatible with NPT (National Pipe Taper) threads without an adapter. For installation into an NPT port, you will need a BSPP (G) male to NPT female adapter to ensure a proper, leak-free seal.

The sensor requires a DC power supply between 10 and 32 volts. The supply must be capable of providing sufficient current to drive the loop (up to 20mA). A common 24V DC industrial power supply is typically used. Ensure your receiver (PLC input, etc.) is compatible with a loop-powered 4-20mA signal source.
