Features
- Temperature compensated Infrared sensors for detection of either Hydrocarbon gases or Carbon Dioxide.
- Plug-in, separately certified Ex d sensor.
- Versions with or without display window.
- Window version menu operates via a magnetic pen eliminating the need to open the flameproof enclosure.
- Protective weather guard can be optionally fitted.
- Can be used in conjunction with new LC Series single and multichannel control units in addition to the standard MCU range.
- Output - 4 to 20 mA dc.
- 8 to 24 volt dc operation.
- Display version is fitted with 3 control relays.
- Various cable gland thread sizes available.
Type FGD10A - Display Version
This version has a clear
window behind which is
fiited 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.
Configuration is carried out by means of a special hand-held unit which connects to the gas detector via a standard USB cable.
FGD10B Calibration Unit

The FGD10B is calibrated using a purpose designed plug-in hand held calbration unit. Calibration of the 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.
