Crowcon F-Gas Detector

A high quality infrared fixed-point detector that delivers dependable detection of freon gases

Overview

Overview

Housed within an IP54 rugged enclosure, the F-Gas Detector is suitable for use in non-hazardous areas such as plant or switchgear rooms. 

In addition to protecting personnel from toxic gas risks, installing the F-Gas detector also helps to reduce the risk of leakage of powerful 'greenhouse gases' into the environment.

 

Accurate and reliable

  • Superior IR sensor technology - provides fast, stable and dependable performance with low maintenance and long life. Unlike cheaper semi-conductor type sensors the F-Gas detector is not affected by other types of gas or changes in temperature or humidity

Simple and versatile

  • Tri-coloured LED's - indicate the operating status of the detector, and in combination with the function keys, facilitate simple adjustments such as zero and calibration
  • Choice of output signals - the analogue output signal can be set as 4-20mA, 0-20mA, 0-2V, 0-5V or 0-10Vdc for compatibility with virtually any control system

Long life with low maintenance costs

  • No consumable parts - provides many years of service with no requirement to replace the sensor or any other components
  • Simple to test - requires a bi-annual gas check only. Re-calibration is only necessary if readings are out of range
  • IP54 rated enclosure - provides good protection from dust and water ingress in indoor environments

Safety and compliance

  • F-Gas regulations compatible - enables F-Gas suppliers and user to comply with the mandatory European F-Gas regulations
  • Rapid gas leak detection - provides an early warning that gas is leaking and thus maintains system efficiency and reduces expensive gas replacement costs
  • Environmental protection - helps to reduce the risk of leakage of powerful 'greenhouse gases' into the environment
