Description

The PR19C-RS-020K pressure sensor utilizes a high-stability sensing element to deliver precise measurements of low-pressure gases or air. Its digital RS485 interface communicates via the Modbus RTU protocol, providing excellent immunity to electrical interference and enabling daisy-chaining of multiple sensors on a single bus, which is ideal for distributed monitoring systems.

Constructed with an industrial-grade housing, this sensor is designed for reliable operation in demanding environments such as HVAC balancing, cleanroom pressure monitoring, and light industrial pneumatic control. The integrated 1-meter cable terminates in flying leads for direct connection to terminal blocks or RS485 converters.

Key Features

  • High-accuracy, low-pressure sensing with excellent repeatability.
  • RS485 Modbus RTU protocol for seamless PLC and DAQ system integration.
  • Wide operating voltage range (10-32 VDC) supports various industrial power supplies.
  • Robust G1/4 threaded stainless steel pressure port for secure sealing.
  • Compact, durable housing designed for panel or inline mounting.
  • Pre-wired with a 1-meter cable for simplified installation and reduced wiring time.
  • Optimized performance-to-cost ratio for industrial and commercial applications.

Applications

  • HVAC system static pressure monitoring and duct air flow verification.
  • Industrial process control for low-pressure gas and air lines.
  • Cleanroom and laboratory pressure differential monitoring.
  • Pneumatic control system feedback and regulation.
  • Building automation for fan and damper control loops.

Frequently Asked Questions

What is the communication protocol for the RS485 output on this sensor?

The RS485 interface on the PR19C-RS-020K uses the Modbus RTU protocol. This industry-standard protocol allows for easy integration with Programmable Logic Controllers (PLCs), SCADA systems, and data acquisition modules that support Modbus communication. You will need to configure the sensor's slave address and baud rate (typically 9600 or 19200 bps) as per your system requirements.

What is the power supply requirement for this pressure sensor?

This sensor operates on a wide-range DC power supply from 10 to 32 volts. This flexibility allows it to be powered by common industrial 12V or 24V DC power supplies. Ensure your power source can provide clean, stable voltage within this range for optimal performance and accuracy.

Can this sensor measure negative pressure (vacuum)?

No, the PR19C-RS-020K is specified for a 0 to 20 kPa gauge pressure range, meaning it measures pressure relative to atmospheric pressure. It is not designed for vacuum or absolute pressure measurement. For vacuum applications, you would require a sensor with a range that includes negative values (e.g., -100 kPa to 0 kPa).

What type of media is this pressure sensor compatible with?

This sensor is suitable for measuring clean, dry, non-corrosive gases such as air or nitrogen. The sensing diaphragm and G1/4 port are not typically rated for aggressive media, liquids, or particulates. For liquid or corrosive gas applications, a sensor with a compatible wetted material (like 316 stainless steel) and appropriate sealing is required.
