Description

The PR-PT300-S3 pressure transducer utilizes a robust ceramic capacitive sensing element, known for its long-term stability and resistance to mechanical fatigue, capable of withstanding over 100 million pressure cycles. This design provides inherent protection against overpressure and burst conditions, making it suitable for harsh hydraulic and pneumatic systems.

Engineered for industrial OEM applications, the transmitter features a compact form factor with a G 1/2 male thread process connection and a Hirschmann-style electrical connector. Its 4-20mA output ensures compatibility with standard PLC analog input modules, distributed control systems (DCS), and data acquisition units, providing a noise-immune signal ideal for pump stations, energy management, and process automation.

Key Features

  • Ceramic measuring cell for high-pressure applications up to 600 bar, offering superior burst pressure resistance.
  • Fully welded 304 stainless steel (SUS304) housing and diaphragm for corrosion resistance in water and compatible media.
  • Integrated signal conditioning with automatic temperature compensation (0–50°C) for low thermal drift.
  • EMI/RFI protected circuitry and glue-filled encapsulation for waterproofing (IP68 level) and environmental durability.
  • Wide operating voltage range of 12–30V DC, standard for two-wire 4-20mA loop-powered transmitters.
  • Designed to withstand high levels of vibration, mechanical shock, and erosive media.
  • Compliant with CE and RoHS directives for use in regulated markets.
  • G 1/2 industrial thread process connection for secure installation into pipelines and manifolds.

Applications

  • Hydraulic power unit and pump station pressure monitoring and control.
  • Industrial process control and automation in water treatment and energy plants.
  • High-pressure testing and monitoring in mechanical engineering and R&D.
  • Pneumatic system controls and compressor discharge pressure sensing.
  • HVAC system refrigerant and chilled water loop pressure measurement.

Frequently Asked Questions

What is the power supply requirement for this 4-20mA pressure sensor?

The PR-PT300-S3 operates on a standard two-wire, loop-powered 12-30V DC supply. The 4-20mA output signal is generated by modulating the current draw within this voltage range, requiring no separate power wiring. Ensure your PLC analog input module or receiver can provide at least 12V DC within the loop.

What media is the sensor compatible with, and what is the process connection?

This transmitter is designed for use with water, oils, and compatible gases, especially when used with a pulsation damper. It features a G 1/2 (ISO 228-1) male thread process connection for direct installation into pipelines, manifolds, or pressure ports. The 304 stainless steel wetted parts provide good corrosion resistance for many industrial fluids.

How accurate is this pressure transducer, and does it require calibration?

The sensor offers a high accuracy of ±0.5% of Full Scale (FS). It is factory calibrated and includes automatic temperature compensation from 0 to 50°C to minimize thermal error. For critical applications, periodic field verification against a calibrated pressure standard is recommended to ensure long-term measurement integrity.

Is this sensor suitable for outdoor or wet environments?

Yes. The transducer features a glue-filled, hermetically sealed electronics compartment and a fully welded stainless steel housing, providing protection equivalent to IP68. This makes it resistant to water ingress, dust, and capable of withstanding harsh environmental conditions typical in industrial and outdoor installations.
