电磁的气体探测器

Detector the gas strength which examines the sensor transforms the electrical signal, passes commits a footfault the cable to transmit the controller, the gas strength is higher, the electrical signal is stronger, when the gas strength achieves or surpasses the alarm point which the warning controller establishes, the alarm apparatus send out the alarm, and may start the solenoid valve, the exhaust fan substandard association equipment, removes the hidden danger automatically.

探测器将传感器检测到的气体浓度转换成电信号，通过线缆传输到控制器，气体浓度越高，电信号越强，当气体浓度达到或超过报警控制器设置的报警点时，发出报警信号，并可启动电磁阀、排气扇等外联设备，自动排除隐患。
