Gas Detectors - ExDetector HC-100

  • Detection of combustible gases and vapours
  • Measuring range: 0–100 % LEL
  • Catalytic combustion measuring principle
  • ATEX-conformity for Zone 1 and 2
  • 3-wire technology (24 V DC, 4–20 mA, ground)

Add to compare
  • The ExDetector HC-100 is a gas measuring and alarm system designed for detecting combustible gases and vapours in hazardous areas. It uses catalytic combustion as its measuring principle, providing a linear 4-20 mA signal. The system includes a probe, evaluation system, and controllable devices such as fans, warning screens, and solenoid valves.
  • It is ATEX-conformity for use in zones 1 and 2, with options for wall mounting (HC100-M) or duct mounting (HC100-T/HC100-K). The system offers safety measures through technical and organisational actions, including visual and audible warnings.
  • The HC100-M is a standard wall-mounted device, while HC100-T and HC100-K are duct-mounted with separate transmitters. The system is designed for reliable operation in hazardous environments, with features like one-man calibration, 3-wire technology, and a wide temperature range of -20°C to +55°C.

Use Cases

  • Measurement and indication of the actual concentration of potentially explosive gases and vapours
  • Monitoring and warning of these gases
  • Triggering safety measures (fans, disconnections, visual and audible alarms)

Capabilities

  • Continuous detection of combustible gases and vapours in air
  • Operation in Zone 1 and Zone 2 hazardous areas
  • Electrical output via 4–20 mA for connection to certified evaluation systems
  • Supported mounting configurations: wall-mounted and duct-mounted variants
