Information About S301-IRF-R22
The S301-IRF-R22 is a Honeywell infrared refrigerant gas sensor developed for compatibility with the 301-EM gas monitoring controller. It is calibrated specifically for R22 refrigerant and delivers accurate concentration readings across a 0–1000 ppm measurement range. The sensor outputs a standard 4–20 mA signal for reliable communication with compatible monitoring and alarm systems. Designed for flexible power input, it operates on 22–27 VAC at 48 VA (50/60 Hz) or 22–38 VDC up to 2 A maximum, making it suitable for commercial HVAC and mechanical room installations.
Key Features:
- R22-Specific Detection: Calibrated for accurate monitoring of R22 refrigerant gas.
- 0–1000 ppm Measurement Range: Enables precise leak detection within typical exposure limits.
- 4–20 mA Output Signal: Provides standardized analog output for control system integration.
- 301-EM Compatibility: Designed for use with Honeywell 301-EM gas monitoring controllers.
- Dual Power Options: Operates on 22–27 VAC (50/60 Hz) or 22–38 VDC.
- Infrared Sensing Technology: Enhances stability and reduces cross-sensitivity.
- Continuous Monitoring Capability: Suitable for mechanical rooms and refrigeration spaces.
The S301-IRF-R22 delivers the reliability and precision required for refrigerant leak detection and safety monitoring in commercial HVAC systems.
