The prime use of the flammable gas detector is for detection of flammable gas (LNG or LPG) below the lower explosive limit of the gas. The flammable gas detector is designed to give an audio and visual warning when the factory preset alarm level of gas has been exceeded.


The gas detector has an internal sounder and an LED on the front panel which indicates the alarm condition. The flammable gas sensor controller has a volt free external output which is used to drive external loads such as solenoid or shut off valves. The output is a SPCO relay rated 1 A.

  • Low cost highly reliable sensor.
  • Suitable for Methane, Butane, Propane (Natural gas, Camping gas, heating gas).
  • Compact, robust moveable sensor.
  • Gives and audio and visual alarm at sensor. 12 - 24 VDC operation
  • Switched Volt free o/p contacts, Comm, NO, NC
  • FAIL SAFE operation. If power is lost the output contact will changeover
  • Can be installed by owner
  • Not affected by any other non hydrocarbon gases, changes in temperatures, or draughts.

The DA2010-04 gas detector is supplied with:

  • 3m Cable and 2.1mm DC Plug
  • Gas sensor/ gas detector unit with built-in audio sounder and visable LEDs.



Caravan and Boats

The storage of LNG and LPG on boats and caravans represents a risk of explosion due to leaky unions and pipes . The DA2010 offers a highly reliable low cost method of detection using a 12 - 24v supply
