WG.NG

WG-22.NG microprocessor-controlled detector is used for continuous monitoring of carbon monoxide (CO) levels in air. The monitoring is performed in premises where the gas is likely to occur, through periodic measuring of CO levels. When the preset threshold levels are exceeded, visual and acoustic alarms of the detector are engaged and its control outputs are activated.

Scope of application

  • Closed garages and underground parking lots – ventilation control
  • Boiler rooms with furnaces fuelled by solid or liquid fuels
  • Gas-fuelled boiler rooms
  • Production buildings where CO is likely to occur (technological processes)
  • Permanently manned premises adjacent to boiler rooms
  • Premises with equipment fuelled by coke-oven gas

Features

  • Measurement of carbon monoxide at extremely low levels;
  • Easily exchangeable sensor unit;
  • Built-in microprocessor controlling all functions of the detector = reliability, work stability, temperature compensation, fully automatic unit;
  • Gas detector + power supply + siren + control unit – all in one solid case, IP43;
  • Two (or three) independent alarm thresholds calibrated to industry standards or tailored to customer’s requirements;
  • FAULT relay output triggered by detector failure, blown fuse or power supply failure;
  • 12VDC alarm output to control external sirens or lamps;
  • 12VDC power supply – model WG-22A; option: 24VAC/DC;
  • Optional: built-in battery back-up (up to 6h) – model WG-22B;
  • All detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).

Detection of substance/property in other areas or other substances/properties is possible = special execution, requires consultation.
In special cases, it is possible to select the detector parameters for a specific application = required analysis of the conditions of use.
