Status Scientific Gas Detectors
Flameproof Fixed Gas Detectors
FGD10 Infrared And Non-Infrared Series Fixed Gas Detectors for Flammable or Toxic Gases and Oxygen.
Flameproof Fixed Gas Detectors are used in Potentially Explosive Atmospheres where, due to the nature of the environment or the industrial process taking place, there is the risk of an incendive spark from electrical apparatus causing an explosion to occur and the organisation responsible for the safety of the area requires that electrical equipment be enclosed within a flameproof enclosure (also known as an FLP, Ex d or explosion-proof enclosure).
Examples are the oil, gas and chemicals industries.
The series comprises fixed detectors with or without a window and digital display. They can be supplied either in cast aluminium (standard type) or grade 316 stainless steel (suffix ‘-SS’ ).
The detectors are fitted with a single sensor that be either an Infrared Sensor, for the detection of Hydrocarbon gases or Carbon Dioxide, a ‘Pellistor’ Catalytic Sensor for detection of both Hydrocarbon gases and Hydrogen or an Electrochemical Sensor for the detection of specific toxic gases and oxygen.
Versions are available for detection of the following common gas types:-
Gas Type
- Acetylene >>
- Ammonia >>
- Carbon Dioxide >>
- Carbon Monoxide >>
- Flammable Including Hydrogen >>
- Hydrogen Sulphide >>
- Methane >>
- Oxygen >>
- Propane >>

FGD10B Calibration Unit
Type FGD10A Display Version
This version has a clear window behind which is fitted a 4 digit LCD display. Four magnetically operated switches behind the window allow the user to configure various operating parameters without opening the flameproof cover. The magnetic switches are operated from outside the window by means of a special magnetic pen.
Three control relays are fitted to provide Alarm Level 1, Alarm Level 2 and Fault outputs via individual changeover contacts. In addition to the 4 to 20 mA analogue, an RS 232 communications output is also provided.
Type FGD10B Non-Display Version
The non-display version provides a cost effective monitoring solution in situations where a local display of the gas level is not required. The unit provides a 4 to 20 mA output.
Calibration of the FGD10B can be carried out simply by using ZERO and SPAN buttons inside the instrument provided that the concentration of the calibration gas is the same as that used for factory calibration of the detector (refer to the instrument calibration certificate for details).
Alternatively, the purpose designed plug-in hand held configuration unit shown below may be used together with any appropriate test gas concentration.
FGD10B Calibration Unit
FGD10B Calibration Unit
Calibration of the FGD10B unit requires the removal of the front cover of the flameproof enclosure and therefore must only be carried out under either of the following conditions:-
In a safe area where there is no risk of the presence of an explosive gas.
Within the hazardous area by authorised personnel under controlled conditions after it has been established that no flammable gases are present in the area. Note that a management or health and safety department permit may be required for this to be carried out.
To carry out a calibration, the operator must open the front cover of the unit, plug in the calibration unit and then present zero and span gases to the sensor during the course of the calibration procedure.
