Pro-Range PR12-P120 Pressure Transducer 0-1000 psi, 0.5-4.5V Output, NPT1/4 Thread

This transducer requires a 5V DC excitation voltage to produce its specified 0.5–4.5V ratiometric analog output. The output voltage scales linearly with the applied pressure, where 0 psi corresponds to 0.5V and 1000 psi corresponds to 4.5V. Ensure your power supply is stable and free of noise for accurate measurements.

Connect the transducer's output pin to an analog input pin on your microcontroller (e.g., Arduino). Since the output range is within the typical 0-5V ADC reference range, no additional signal conditioning is required for basic readings. You can map the analog reading (e.g., 0-1023 for a 10-bit ADC) to the corresponding pressure value using the linear relationship between 0.5V and 4.5V.

This sensor features a standard NPT 1/4" male thread. For installation, use appropriate thread sealant (e.g., PTFE tape) on the threads to ensure a pressure-tight seal. Screw the transducer directly into a compatible NPT 1/4" female port on your pressure line or manifold, taking care not to over-torque and damage the housing.

Yes, the PR12-P120 is suitable for measuring pressure in compatible non-corrosive gases and liquids, such as air, water, and hydraulic oils. Ensure the media is compatible with the sensor's internal wetted materials (typically stainless steel). Always avoid exposing the sensor to media outside its specified chemical compatibility range.
