gas leak alarm

Type Immediate alarm type, Combustible catalytic sensor type, Explosion-proof type Power AC 220V/60Hz Battery DC18V, 600mAh, Ni-Cd Gas type LPG, LNG, Town gas(Heavy),Town gas(light) Power consumption 8W(3circuit) Detecting range LEL 0~100 Density to alarm LEL 20 Alarm sign LED yellow light and buzzer sound Breakdown LED red light Reset method Automatic Output Voltage signal : 12VCurrent signal : 4~20mA Contact signal : COM, NO, NC(250V,3A) Use place Boiler room, factory, Gas store room, other gas facilities Operating Temp. & Hum. -20~50, Under 95%(RH) Weight(kg) Dimensions(mm) W320 x H420 x D170(3circuit) It consists with explosion-proof detector that detects the gas leakage, and receiver that displays the gas density by receiving signal from detector. With digital density display method, it allows easy gas density verification. Explosion-proof detector is used in a place with the danger of explosion. When alarming, it can operate with exterior equipment like fan or blinker light. By using the 4~20mA output from gas leakage sensor, it can operate with computer. 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.
