Crowcon F-Gas Infrared Fixed Point Detector

Crowcon F-Gas Infrared Fixed Point Detector

The Crowcon F-Gas detector is a high-quality infrared (IR) fixed-point detector that delivers dependable detection of freon gases. Available for detecting a range of different refrigerant gases and also sulphur hexafluoride (SF6), the Crowcon F-Gas detector can be connected to any control system that accepts an analogue signal.

The Crowcon F-Gas detector utilises a high-quality IR sensor specifically calibrated to detect the F-Gases commonly in use. The F-Gas detector operates from 24Vdc and provides a 4-20mA signal (the output can also be set to 0-20mA, 0-2V, 0-5V or 0-10Vdc). Housed within an IP54 rugged enclosure, the F-Gas detector is suitable for use in non-hazardous areas such as plant rooms 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.

Key Features

• 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.
• LED indicators – Tri-coloured LEDs indicate the operation 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, 0-2V, 0.5V or 0-10Vdc for compatibility with virtually any control system.
• 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 reads are out of range.
• IP54 rated enclosure – provides good protection from dust and water ingress in indoor environments.
• F-gas regulations compatible – enables F-gas suppliers and users to comply with 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.
