Description

The PR12-P120-30-1/8 pressure transducer utilizes a high-quality piezoresistive sensing element to deliver precise and stable pressure readings. Its ratiometric 0.5–4.5V output provides a linear signal directly proportional to the applied pressure, simplifying integration with analog-to-digital converters (ADCs) on microcontrollers like Arduino, Raspberry Pi, or industrial PLCs.

Housed in a robust, compact casing, the sensor is designed for direct installation into pneumatic lines and low-pressure hydraulic systems via its NPT 1/8 threaded connection. This design ensures a secure seal and minimizes space requirements, making it ideal for embedded applications and panel mounting where real-time pressure monitoring is critical.

Key Features

  • Precision Low-Pressure Sensing: Accurately measures pressures from 0 to 30 psi (gauge) for precise system monitoring.
  • Ratiometric Analog Output: Delivers a 0.5V to 4.5V linear output signal when powered by a stable 5V DC source.
  • Compact NPT Threaded Port: Features a standard NPT 1/8 male thread for secure, leak-resistant installation in fluid and gas lines.
  • Robust & Durable Construction: Engineered with a high-value build for reliable operation in HVAC, automation, and pneumatic control environments.
  • Fast Dynamic Response: Provides quick reaction to pressure changes for real-time control and feedback loops.
  • Wide Operating Temperature Range: Designed to maintain accuracy across typical industrial temperature conditions.

Applications

  • HVAC system duct pressure monitoring and damper control.
  • Pneumatic control circuits and air compressor pressure regulation.
  • Low-pressure hydraulic system monitoring in industrial machinery.

Frequently Asked Questions

What is the required power supply for this pressure transducer?

The Pro-Range PR12-P120 transducer is designed to operate with a 5V DC power supply. This voltage powers the internal sensing circuitry and generates the ratiometric 0.5V to 4.5V analog output signal, where 0.5V corresponds to 0 psi and 4.5V corresponds to the full 30 psi pressure reading.

How do I interface the 0.5–4.5V output with a microcontroller like Arduino?

Connect the transducer's output pin to an analog input pin on your microcontroller (e.g., Arduino). Since the output range (0.5V–4.5V) is within the typical 0V–5V ADC range, you can read it directly. Apply scaling in your code to convert the ADC reading (e.g., 0–1023 for a 10-bit ADC) into a precise pressure value in psi.

What type of thread does this sensor have, and is it suitable for gas lines?

This sensor features a standard NPT 1/8 male thread, which is commonly used for sealing connections in low-pressure pneumatic and hydraulic systems. It is suitable for non-corrosive gas and air lines. Ensure proper sealing with thread tape or sealant rated for your media to prevent leaks.

Can this sensor measure negative pressure or vacuum?

No, the PR12-P120-30-1/8 model is specified as a gauge pressure transducer with a range of 0 to 30 psi. It measures pressure relative to atmospheric pressure and is not designed for measuring vacuum (negative gauge pressure) or absolute pressure. For such applications, a different sensor model would be required.
