Description

The PR12-P120 series pressure transducer utilizes a high-stability sensing element, likely a piezoresistive silicon strain gauge, to convert applied pressure into a precise electrical signal. The 0.5–4.5V output is ratiometric to the supply voltage, providing excellent noise immunity and simplifying interface with microcontrollers, PLCs, or data acquisition systems.

Constructed with a robust housing and NPT1/4 threaded port, this sensor is designed for direct installation into hydraulic test stands, compressor lines, industrial machinery, and process control systems. Its performance is characterized by high accuracy, low hysteresis, and reliable operation across a wide industrial temperature range.

Key Features

  • Precision Pressure Sensing: Engineered for accurate and repeatable measurement of fluid and gas pressures up to 500 psi.
  • Ratiometric Voltage Output: Provides a 0.5–4.5V DC signal linearly proportional to both pressure and supply voltage, ensuring stable readings.
  • Industrial-Grade Connection: Features a standard NPT 1/4" male thread for reliable, pressure-tight sealing in piping systems.
  • Compact & Durable Build: Space-saving design with a rugged housing capable of withstanding demanding operational environments.
  • Fast Dynamic Response: Delivers quick signal updates for monitoring pressure fluctuations and transients in real-time.
  • Wide System Compatibility: The analog voltage output is directly compatible with most microcontrollers (Arduino, Raspberry Pi, PLC analog inputs) using a simple ADC interface.

Applications

  • Hydraulic System Monitoring: Real-time pressure measurement in hydraulic power units, presses, and lifting equipment.
  • Pneumatic Control Systems: Monitoring and feedback for air compressor outputs, robotic grippers, and valve actuation systems.
  • Industrial Process Control: Integration into PLC-controlled systems for pump, filter, and pipeline pressure supervision.
  • Automotive & Motorsport Testing: Measuring fuel rail pressure, oil pressure, or turbocharger boost in test rigs and vehicles.
  • Water & Irrigation Management: Monitoring pump discharge pressure and system pressure in agricultural and water distribution networks.

Frequently Asked Questions

What is the required supply voltage for this pressure transducer?

This transducer is designed for a typical excitation voltage of 5V DC. The 0.5–4.5V output signal is ratiometric, meaning its span scales proportionally with the supply voltage, ensuring stable performance even with minor supply variations.

How do I interface the 0.5–4.5V output with an Arduino or PLC?

Connect the sensor's output pin to an analog input on your microcontroller (e.g., Arduino) or PLC. The 0.5V (0 psi) to 4.5V (500 psi) range maps directly to the ADC's reference. Ensure your system's analog input can accept voltages up to 4.5V, or use a voltage divider if necessary.

Can this sensor measure other pressure ranges or provide a different output?

The PR12-P120 series is highly configurable. Custom pressure ranges up to 100 MPa and alternative outputs like 4-20mA, 0-10V, or RS485 Modbus are available directly from the manufacturer (Pro-Range) upon request for specific project requirements.

Is the NPT1/4 thread suitable for high-pressure hydraulic applications?

Yes, the NPT (National Pipe Taper) 1/4" thread is a standard for industrial fluid power connections. When properly sealed with thread tape or a suitable sealant, it provides a robust, leak-proof connection suitable for the sensor's rated 500 psi operating pressure.
