Description

The PR12-P120 pressure transducer utilizes a high-stability sensing element to convert applied pressure into a precise analog voltage signal. Its ratiometric 0.5–4.5V output simplifies interfacing with microcontrollers, PLC analog inputs, and data acquisition systems, requiring only a stable 5V DC excitation voltage.

Engineered with a robust stainless steel body and an NPT1/4 male threaded port, the sensor is designed for direct installation into pressurized systems with a standard sealant. Its compact form factor and reliable performance make it suitable for continuous operation in industrial automation, HVAC pressure monitoring, fluid power systems, and automotive testing applications.

Key Features

Wide Pressure Sensing Range: Measures from 0 up to 150 psi (approximately 10.3 bar) with high linearity.
Ratiometric Voltage Output: Generates a linear 0.5V (at zero pressure) to 4.5V (at full scale) signal when powered by 5V DC.
Industrial-Grade Threaded Connection: Features a standard NPT 1/4-inch male thread for secure, leak-proof system integration.
Robust Stainless Steel Construction: The housing provides excellent durability and resistance to vibration and corrosion.
High Overpressure Capability: Built to withstand pressure spikes beyond its rated range for enhanced system safety.
Fast Dynamic Response: Low internal damping ensures quick tracking of pressure changes for real-time control.

Frequently Asked Questions

What is the required supply voltage for the 0.5–4.5V output signal?

The transducer's ratiometric output is designed for a stable 5V DC supply. The output voltage will scale linearly from 0.5V at zero pressure to 4.5V at the full 150 psi pressure. Ensure your power source provides a clean, regulated 5V (±0.25V) for accurate readings.

How do I interface this transducer with an Arduino or PLC?

Connect the sensor's Vcc and GND wires to a stable 5V power source. The signal wire outputs an analog voltage (0.5–4.5V) which can be read directly by an Arduino's analog input pin (A0-A5) or a PLC's 0-5V analog input module. Use the map() function in code to convert the ADC reading to pressure units.

Is the NPT1/4 thread suitable for liquid pressure measurement?

Yes, the stainless steel construction and NPT1/4 port are compatible with water and non-corrosive hydraulic fluids. For installation, apply a suitable thread sealant (e.g., PTFE tape or liquid thread sealant) to the male threads to ensure a leak-proof connection. Ensure the media is within the sensor's specified compatibility range.

What is the accuracy and response time of this pressure transducer?

The PR12-P120 offers a typical accuracy of ±0.5% of full scale (150 psi) and a fast response time of less than 5 milliseconds. This combination provides precise, real-time pressure feedback suitable for dynamic system control, process monitoring, and data logging applications.
