Description

The PR19C-PA-050K is a piezoresistive pressure transducer that converts applied pressure into a proportional 4-20mA current signal. Its sensing element and integrated signal conditioning circuitry are housed in a durable, compact metal body, ensuring stable performance in industrial environments such as pneumatic control, HVAC duct pressure monitoring, and low-pressure process lines.

This two-wire transmitter requires a DC loop power supply (10-32V) and outputs a 4mA signal at zero pressure and a 20mA signal at full scale (50 kPa). The G1/4 threaded port allows for direct mechanical installation into systems, while the included 1-meter cable provides convenient wiring to terminal blocks or junction boxes, making it a ready-to-deploy solution for automation and monitoring applications.

Key Features

  • Piezoresistive MEMS sensing technology for precise low-pressure measurement.
  • Fully signal-conditioned 4-20mA current loop output ensures high noise immunity.
  • Robust stainless steel sensing diaphragm and housing for long-term durability.
  • Wide operating temperature range suitable for industrial and commercial HVAC applications.
  • Zero and span calibration performed at the factory for plug-and-play operation.
  • Compact form factor (30mm diameter, 92mm length) for installation in confined spaces.
  • High-value build optimized for reliable performance in cost-sensitive automation projects.

Applications

  • Pneumatic system pressure monitoring and control in automation machinery.
  • Differential pressure measurement across filters in HVAC and cleanroom systems.
  • Low-pressure process monitoring in water treatment, chemical dosing, and beverage lines.
  • Integration into PLC-based control panels for industrial process supervision.
  • Fan and blower static pressure measurement in ventilation and air handling units.

Frequently Asked Questions

What is the wiring diagram for this 4-20mA pressure sensor?

This is a two-wire transmitter. Connect the positive terminal of your 10-32V DC power supply to the red wire of the sensor's cable. Connect the black wire to the positive input of your current-reading device (PLC analog input, data logger, etc.). Finally, connect the negative terminal of your power supply to the negative input of your reading device, completing the loop. The output current (4-20mA) flows through this loop.

Can the pressure range or output signal be customized?

Yes, the Pro-Range series sensors are often available with customization options. You can contact the supplier or manufacturer to request different pressure ranges (e.g., 0-25 MPa), alternative output signals (such as RS485 Modbus), or different thread sizes (like G1/2 or M20x1.5). Lead times and minimum order quantities may apply for custom configurations.

Is this sensor suitable for measuring liquid pressure?

The PR19C-PA-050K uses a stainless steel diaphragm and is generally compatible with clean, non-corrosive liquids and gases. However, for aggressive media, you must verify the wetted material compatibility (typically 316 stainless steel). Ensure the media is compatible with the G1/4 thread material and that installation follows proper sealing practices to prevent leaks.

What is the accuracy and long-term stability of this sensor?

While specific accuracy class (e.g., 0.5% FS) should be confirmed via the official datasheet, sensors in this category typically offer good accuracy and repeatability for industrial monitoring. The piezoresistive sensing technology provides stable performance over time, with minimal drift when operated within its specified temperature and pressure limits, making it reliable for continuous process control.
