The GDA 40126 Gas Detection Controller is a standalone gas detector unit with inbuilt display, sounder, flasher, relays and alarm driver. Available for Flammable gases such as LNG, LPG, Propane, Hydrogen, Acetylene, Solvents, and other flammable vapours. Designed to be used in Non-hazardous areas with the GDA 2500 series easily replaceable sensor modules.
Designed, manufactured and supported locally in Australia.
This product is being replaced by the SENKO SI-100-009 Combustable Sensor
The GDA 40126 has 2 user relays which can be programed to operate at any level within the gas detectors operational range as well as an independent fail safe fault relay. The unit's alarm state is indicated by the display and by flashing LEDs additionally there is an o/p to drive a 24 VDC sounder / flasher (AVR-20) all of which can be muted from the front panel.
Poisoning: GDA sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.

|Sewage Treatment Plant Monitoring|
The presence of Hydrogen Sulphide can be detected by using the Gas Detection Australia GDA 2529 gas sensor to detect leaks of Hydrogen Sulphide and evoke deodorisation plant. The SI-100C gas sensor can be used to monitor for leaks of LEL levels of methane gas. In digester applications Carbon dioxide can be detected using the GDA 4350
Designed, Manufactured and Supported in Australia.
