LPG Gas Detector PC3-3012



  • High Price-Performance; Ratio PC3 has a certain higher price-performance ratio considering its substitutes in the market.
  • Well-Suited Solution for Light Indusrty; PC3 is specially designed for the light industry as a Category 3 device.
  • Accurate Readings; Electrochemical, and Catalytic sensors undoubtedly provide an accurate and sensitive measurement.
  • Ready to Operate; 4-20mA Analog is provided onboard to operate properly without any additional setup. Additionally, it can be integrated into other systems with Modbus RS485 RTU and relay module.
  • Automatic Calibration; Detector calibration can be done automatically via preset values recorded in detector software once calibration requirements are provided.
  • Fail-Safe Technology Alarming; Alarm 1 and Alarm 2 relays are easy to set to default LEL, ppm, VOL levels. The fault relay output properly indicates fault status.
  • Robust and Reliable Housing; Epoxy painted aluminum housing and IP65 protection class allow to use in harsh environmental conditions.
  • Universal Outputs; 4-20mA Analog, Modbus RS485 RTU, and relay outputs are simple to operate efficiently and they are universally usable in any control panel.
