Pro-Range PR19C-PA-250 Pressure Sensor 0-25 MPa, 4-20mA Output, G1/4 Thread, 1m Cable

Connect the positive (red) wire of the sensor's cable to the positive terminal of your 10-32 VDC power supply. Connect the negative (black) wire to the positive input of your 4-20mA receiver (e.g., PLC analog input module). Finally, connect the negative terminal of your receiver to the negative terminal of the same power supply, completing the loop. The sensor modulates the current flow (4-20mA) through this loop based on the measured pressure.

The standard sensing element is typically stainless steel, offering good corrosion resistance to many oils, water, and mild chemicals. However, for highly aggressive media (acids, strong alkalis), you must verify the wetted materials (usually 316 stainless steel) are compatible. The G1/4 thread seal must also be appropriate for the fluid. Always consult the manufacturer's datasheet for specific media compatibility before installation.

Industrial-grade pressure transmitters like the PR19C-PA-250 typically offer an accuracy of ±0.5% Full Scale (FS) or better. Long-term stability is a key feature, often specified as ±0.1% FS per year, ensuring readings remain reliable over extended periods with minimal drift. For precise figures, refer to the official Pro-Range technical datasheet for the specific model's calibration certificate data.

The 1-meter cable is integrated into the sensor housing. It can be extended by splicing and soldering, but this must be done with proper waterproofing and shielding to maintain signal integrity and IP rating. For best practice, use a shielded, twisted-pair cable for the extension and protect all connections with a sealed junction box to prevent moisture ingress and electrical noise.
