Description

GasDetek Sentinel CO Sensor

Applications

  •  Due to the sensors’ high quality and efficiency, these sensors can be used in commercial and industry environments such as car parks and mines
  •  The design is robust but still allows for accurate and reliable detection
  •  This sensor is capable of detecting two to three programmed levels of CO gas concentrations and is able to transmit the data
  • to a computer at a remote location as well being used as a stand-alone detector.(Stand alone sensors are calibrated for one detection level)
  •  When coupled to the Sentinel system software the sensor is able to provide all relevant information regarding the sensor status.
  •  Data is continuously sent from the sensor to the computer

Function

  •  As CO gas has no odour, the use of CO sensors make for a safer environment, thus the detection of this dangerous gas becomes of utmost importance
  • CO is a by-product and is normally produced by either the burning of fossil fuels such as wood, coal, gas or other flammable Materials
  •  The Sentinel CO sensors can be calibrated to detect at different levels allowing appropriate action to be taken to avoid accidents or dangerous situations
