gas leak alarm

Type Single circuit, Immediate alarm type, Exposed type, Combustible catalytic sensor type Power DC 12V Gas type LPG, LNG, Town gas(Heavy),Town gas(light) Power consumption 1.3W Density to alarm LPG, Town gas(Heavy): 0.06~0.45%LNG, Town gas(light): 0.06~1.25% Alarm sign LED yellow light and buzzer sound Reset method Automatic Alarm output DC 10V Use place Home use Operating Temp. & Hum. -20~50, Under 95%(RH) Weight(g) 63 Dimensions(mm) W73 X H110 X D37 With the waterproof function, it usually is used in a place where is exposed to water or humidity. Once gas leakage gets to the level of alarm density, sensor makes alarm sign. For the stable operation of sensor, it stabilized the sensor by using initial delaying circuit. It operates stably for the change of temperature and voltage. With switching constant voltage method, it minimized the power consumption and stabilized the sensor. By delivering leakage signal to gas controller, it allows to stop up the gas valve automatically. It is easy to install for anybody. It is not expensive to purchase.
