The prime use of the boat / caravan gas detector is the detection of flammable gas (LNG or LPG) below the lower explosive limit of the gas. The domestic/ caravan gas detector is designed to give an audio and visual warning that a preset 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 boat / caravan gas detector 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. The DA2010-04 is powered from the user DC power supply 12 - 24 VDC.


  • 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.



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
