Flammable gas detector(SI560LPG) is a separated gas detector, composed of detection part and 

control part which displays gas concentration from the signal received from the detection part. 

Detection part has a structure of flameproof enclosures. In order to stabilize the sensor operation, 

we introduced a stabilization step at an initial stage of operation. SI560LPG is also robust for the 

change of surrounding temperature and input voltage and designed to consume the minimum 

electric power. Automatic shut-off gas valve is operated by transmitting a gas leakage signal to 

automatic shut-off gas valve.
