Overview.
Fixed toxic and harmful gas detector is a new gas detector made by our company, which adopts imported sensors and a new 32-bit low-power processor; Instrument panel display interface, numerical value and progress bar display at the same time, beautiful and generous; The circuit adopts 4-layer wiring, which is stronger to weak signal and anti-interference; Independent high-precision imported 16 bit AD chip and unique signal processing algorithm, higher and more stable measurement data accuracy; 4 ~ 20mA, RS485, 200 ~ 1000Hz multiple output signals can be selected, convenient access to various alarm controllers, PLC, DCS and other control systems; The design of explosion-proof structure can be used in all kinds of dangerous industrial places.
Major function.
It has the functions of real-time display, signal transmission, sound and light alarm and two groups of relay alarm. It can be equipped with WiFi, GPRS and other wireless signals. The detector has two groups of relays (switch signal) inside, which can control the fan, sound and light alarm, solenoid valve and other equipment.
