When the SG500 senses the presence of gas it sends a 4-20mA signal to the detector. The controller then operates a pre-alarm relay which activates sounders or beacons. If the gas levels continue to rise then the main alarm relay breaks the electrical supply to a safety shut off valve. This is fixed at 20% LEL of natural gas.

For a more advanced Methane or LPG gas sensor check out the SGM595 Gas Sensor.

FAQs

Can the SG500 Methane or LPG Gas Sensor be used for other types of gas?

The SG500 is specifically designed to monitor Methane or LPG. For monitoring other types of gas, it would be best to check out other specific detectors.

Where should I install the SG500?

The SG500 natural gas 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.

Natural gas is lighter than air and will therefore rise, meaning the SG500 sensor should be mounted 300mm from the ceiling of the protected area.

LPG is heavier than air and will therefore drop, meaning the SG500 sensor should be mounted 300mm from the floor of the protected area.
