The header gas sensor uses the current microelectronics processing technology, With the original foreign imported gas sensor, When the target gas enters the gas probe portion, The internal sensors make the first time, The sensor generates a certain power signal depending on the concentration of the gas, After the signal is amplified, By CPU through AD sampling, temperature compensation, intelligent calculation, converted into the corresponding standard voltage signal (such as 0-5V), current signal (such as 4-20 mA), standard digital signal (such as bus RS-485) and then the signal to PLC, DCS, alarm control host, upper machine and other systems for unified display, management and control, In addition, the equipment is equipped with a relay (switching quantity signal), Can control the sound and optical alarm, fan, solenoid valve control equipment for linkage, To maximize the safety of your life and property.
