Gas detector for Ex zone 1 (4-20 mA output/digital)

  • The gas detector measures the selected gas concentration
  • The gas detector is part of the digital KIMESSA CANline BUS-Network which is designed for up to
  • 128 gas detectors and alarming units
  • linearized and temperature-compensated digital CANline-BUS-output, 4-20mA or Modbus RTU with optional relays
  • 16…30VDC supply voltage (2-wire, 3-wire or 4wire cable for CANline BUS-Network)
  • digital MODBUS-RTU (RS 485) output signal
  • various gas sensor technologies available (electrochemical, Infrared, pellistor, semiconductor)
  • factory calibration with calibration certificate to the specified measuring range
  • Calibration/ programming are easily carried out with the use of a hand held HAL magnetic sensor
  • water- and dust-proof IP 65 enclosure
  • rust-proof and acid-resitant steel enclosure
  • clearly arranged OLED-Display with concentration- and status information
  • optional 3 potential free relay outputs (to control third party devices)
  • optional relay contacts: various relay functions (manual/auto RESET, Energized/De-Energized)
  • optional relay contacts: Free programmable time delays and alarm levels
  • optional 230 VAC supply for standalone operation
  • The intrinsically safe design facilitates replacement of the electrochemical sensor without the need of a hot work permit
  • ATEX-Class: II 2G Ex d IIC T4 (semiconductor, pellistor and infrared)
  • ATEX-Class: II 2G Ex d ia IIC T4 (electrochemical)
  • Swiss-Made
