Crowcon Gasmonitor Gas Alarm & Control System

Crowcon-Gasmonitor
Crowcon-Gasmonitor

The Crowcon Gasmonitor Plus gas detection monitoring controller is the control system on Crowcon’s 19″ flexible rack model. This micro-control device is used smoothly in the world, both inland and offshore. Gasmonitor Plus gas detection monitoring controllers can monitor up to 16 probes or 32 fire areas per rack. The racks can be supplied separately, or integrated onto walls or floors according to packing standards.

A separate gas level display is provided for each probe. Gas detection monitoring controllers can be built into very large systems and adjusted to each environmental requirement.

GASMONITOR OVERVIEW

Easy to use

  • All daily functions are available from the front of the controller – push buttons for simple control.
  • Unique bar visual function for each channel – provides immediate observation for gas concentrations
  • The usual led warning light on the card displays, all the states of the rack can be checked with just a glimpse.

Flexible architecture

  • Infinitely scala expandable system
  • Module structure – customized mainly on the lowest limit of wiring
  • The same standard as the output industry – which will be fully edested with the current racks – field protection mounting system
  • Relay module options – flexibility and reduced configuration and monitoring connection cable

Simple maintenance

  • Each channel is prohibited separately – safety equipment does not affect during inspection
  • Periodical calibration on the front of the controller – reducing the cost of workers by up to half
  • A global gas card – reducing replacements
