Description

The PR12-P120 series pressure transducer utilizes a high-stability piezoresistive sensing element to convert applied pressure into a precise analog voltage signal. The 0.5–4.5V output is ratiometric to the 5V supply, ensuring consistent accuracy even with minor supply voltage fluctuations. The stainless steel sensing diaphragm and NPT1/4 threaded port provide robust, leak-resistant integration into liquid or gas pressure lines.

Engineered for reliability in demanding environments, this transducer features temperature-compensated circuitry to minimize drift. Its compact form factor and standard electrical interface make it suitable for embedded system monitoring, pump control, and filter status indication where low-pressure accuracy is critical.

Key Features

  • Piezoresistive silicon sensor with high overpressure capability.
  • Ratiometric 0.5–4.5V analog output simplifies ADC interfacing.
  • Stainless steel pressure port with NPT1/4 thread ensures durable, sealed connections.
  • Laser-trimmed calibration provides excellent accuracy and long-term stability.
  • Wide operating temperature range suitable for industrial and HVAC applications.
  • Low power consumption and reverse polarity protection for system safety.

Frequently Asked Questions

What is the wiring diagram for the 0.5–4.5V output?

The transducer typically has three wires: Red (5V DC supply), Black (Ground), and Green or White (0.5–4.5V Analog Output). Connect the output wire directly to an ADC input on your microcontroller or PLC. Ensure the ground references are common between the sensor and your measurement system for accurate readings.

Can this sensor measure both gas and liquid pressure?

Yes, the PR12-P120 transducer is suitable for measuring pressure of non-corrosive, clean gases and liquids compatible with stainless steel. Ensure the media does not contain particulates that could clog the port. For aggressive media, consult the manufacturer for optional diaphragm isolation.

Is the output signal ratiometric to the supply voltage?

Yes, the 0.5–4.5V output is ratiometric. This means the output voltage scales linearly with both the applied pressure and the supply voltage. A stable 5.0V supply is recommended for optimal accuracy, as variations will proportionally affect the output signal.

What is the difference between gauge, absolute, and sealed pressure types for this model?

The PR12-P120-30-1/4 is a gauge pressure sensor. It measures pressure relative to ambient atmospheric pressure. For absolute pressure (referenced to a vacuum) or sealed gauge pressure (referenced to a fixed sealed pressure), you would need to select a different model variant from the same series.
