The SGM595 LPG Gas Sensor is the gas sensor used with the complete range of Duomo conventional detector panels. This is the LPG version of the SGM595. For the Methane CH4 (Natural Gas) see SGM595 Methane Gas Sensor

We have installed and commissioned natural gas and carbon monoxide sensors for applications such as:

  • Boiler rooms
  • Kitchens
  • Car parks
  • Aircraft hangers
  • Factories
  • Shopping centres

The SGM595 is an easy to install product. It sends signals back to the Duomo gas detector panel (please see below) that powers it. Then, the Gas Sensor interprets the signal and can sound alarms whilst turning off gas supplies to the protected area. As a result, a gas cannot escape into the atmosphere.

Because of its automatic drift compensation feature, the SGM595 is now one of our most popular gas sensors. To ensure efficacy and extend sensor life, Duomo recommend servicing at a minimum of every 12 months.

We manufacture all Duomo products to meet relevant European standards and proposals for explosive and toxic gases. The gas industry recognise Duomo for providing a comprehensive range of low cost, high reliability gas detection for many applications.

This LPG Gas Sensor is compatible with complete Duomo conventional Gas detection range GS100MGS300MGS300McBX444McBX150 & BX316.

Can I use the SGM595 Sensor for both Methane and LPG simultaneously?

No, the SGM595 sensor must be set up to detect either Methane or LPG at any given time. It’s calibrated for one type of gas to ensure accurate measurements and performance.

This is the Methane version not the SGM595 Methane version.

What is the expected lifespan of a SGM595?

We recommend that the SGM595 Sensor is replaced every 5 years to ensure protection and accuracy and reaction times

Where should I install my sensor?

LPG is heavier than air and the SGM595 should be mounted 30cm from the lowest point from floor level of the protected area.

The sensor should be mounted in accordance with certain considerations. Do not position next to burners, heaters or ovens where temperatures above the room ambient may be experienced. It is, if possible, better to mount the sensors on the opposite wall. This is, of course, dependant on the size of the protected area.

How do I replace the SGM595 sensor?

When replacing sensors never separate the SGM595 sensor head from its PCB. The sensor is calibrated using the original PCB board and will not function correctly with any other. The complete sensor is replaced and should be replaced every 5 years.

The sensor isn't powering up, what is wrong?

Check that the 12/24 VDC power is present, and that positive and negative polarity has not been
