gas leak alarm

Type Combustible catalytic sensor type Explosion-proof method Inner pressure explosion-proof(ExdII CT4 ) Operating Temperature -20~40 Connecting line VCTF 3Cx0.75mm Dimensions(mm) W127 x H145 x D90 It consists with explosion-proof detector that detects the gas leakage, and receiver that displays the gas density by receiving signal from detector. With the alarming system of 1st, and 2nd gas leakage alarm function, it allows to cope with the danger gradually. 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.
