Pro-Range PR12-P120-200-1/4 Pressure Transducer, 0-200 psi, 0.5-4.5V Output, NPT1/4 Thread

The transducer typically operates on a 5 VDC supply voltage. The output is ratiometric, meaning the 0.5-4.5V signal scales directly with the input supply, which simplifies interfacing with microcontroller ADCs and PLC analog input modules. Always verify the exact supply voltage limits from the datasheet before connection.

Yes, this sensor is suitable for use with compatible non-corrosive liquids and gases. The stainless steel pressure port and sealed construction allow for fluid pressure measurement. Ensure the fluid media is compatible with the sensor's wetted materials (typically stainless steel) to prevent corrosion or damage.

Connect the sensor's output pin to an analog input pin on your microcontroller (e.g., Arduino A0). The 0.5-4.5V range falls safely within the 0-5V ADC reference of most boards. In your code, map the ADC reading (e.g., 0-1023) to the pressure range (0-200 psi) using a linear scaling function, accounting for the 0.5V offset at zero pressure.

This unit features a male NPT1/4 (National Pipe Taper) thread. For installation, you will need a corresponding female NPT1/4 port on your system. Use appropriate thread sealant (e.g., PTFE tape) on the male threads to ensure a pressure-tight, leak-free seal. Do not over-torque during installation.
