SG500 – Methane or LPG Gas Sensor

When the SG500 senses the presence of gas it sends a 4-20mA signal to the detector proportional to the level of gas. The detector then operates a pre-alarm relay – used for remote sirens or visual indicators. If the level of gas continues to rise then the main alarm relay is activated to break the electrical supply to a safety shut off valve and is fixed at 20% LEL of natural gas.
