Product Description
introduce
The YF-8500-4 series is a gas detector designed to detect two types of gases. It is also an explosion-proof fixed type detector for toxic and harmful gases, VOCs, toluene, flammable gases, odorous gases, hydrogen sulfide, oxygen, carbon monoxide, carbon dioxide, flammable gases, hydrogen, methane, ammonia, and other gases. It can be paired with two types of gases at will and can be contacted by sales personnel. The detection principle is that when the target gas enters the gas probe section, the internal sensor will immediately emit an induction. Sensors generate certain electrical signals based on the concentration of gas. After being amplified by the circuit, the signal is processed by the CPU through AD sampling, temperature compensation, and intelligent calculation to output accurate 4-20mA signals, RS485 communication signals, ZIGBEE, NRF, WIFI wireless signals, etc. Customers can collect these signals and use them in conjunction with Yifan Technology's gas alarm control host, PLC, DCS, upper computer and other systems for alarm and data processing.
Product Features
