Description
The FGD 3 Hydrogen Gas Detector uses electrochemical sensor technology to detect the level of Hydrogen in the atmosphere over the range 0 - 4% Volume (0 - 100% LEL). The detectors use the industry standard 4-20mA current loop both to power the detector and to convey the gas levels detected to a control unit. This means that under zero gas conditions 4mA is drawn from the supply, and under full scale gas conditions 20mA is drawn from the supply. The current varies linearly for gas levels between zero and full scale. The detector head uses a two-wire connection.
FGD3 Weatherguard
An optional weather guard is available for installations exposed to the atmosphere or contaminants and is also suitable for use in other areas where hosing down takes place. The weather guard reduces the possibility of water or other contaminants entering into the gas sensor thereby improving the overall reliability of the gas detector in harsh environments. The weather guard is attached with tamperproof screws to ensure that it is not inadvertently removed.
Collector Cone
A collector cone is available which can be fitted around the sensor inlet in order to concentrate any gas present around the sensor and hence improve the detection ability. Mounting brackets are also available.
Mounting Kits
A Swivel Mounting Bracket and Ceiling Mounting Kit is available for use with this range of gas detectors. In addition, a duct mounting kit is also available. Please contact Status Scientific Controls to discuss your particular application.
