Crowcon Xsafe Safe Area Flammable Gas Detector

The Xsafe is a flammable gas detector that uses a poison-resistant pellistor contained within an aluminium enclosure, which has one cable gland entry on the right-hand side, with 3-wire mV or 4-20mA output.

Xsafe flammable gas detectors are calibrated in accordance with EN60079-20-1:2010 so that 100% LEL methane= 4.4% volume gas, 100% LEL propane=1.7% volume gas.

Optionally, the Xsafe can be calibrated in accordance with alternative standards such that 100% LEL methane= 5.0% vol. gas, 100% LEL propane=2.2% vol. gas.

  • Enclosure Material – Aluminium.
  • Operating Temperature – mV: -40 to +80°C (-40 to 176°F) and mA: -40 to +55°C (-40 to 131°F).
  • Humidity – 0-99% RH.
  • Operating Voltage – mA: 10- 30V dc mV:2.0Vdc.
  • Power Requirements – mA:50mA at 24V dc 1.2W mV: 300mA (Typical).
  • Electrical Output – mA: 3- wire 4-20mA (current sink or source) mV: 3- wire mV bridge.
  • Typical signal: 12-15mV/ %LEL CH4.
  • Weight – 1kg (2.2lbs).
