Fixed gas alarm: YT-95H-A series product is a fixed gas detector that monitors the gas concentration in the environment or pipelines 24 hours a day and gives an alarm. Digital integrated module, maintenance is extremely simple and convenient: the air chamber module digitizes the analog signal, no need to disassemble the whole machine, just and unplug the air chamber part, you can return to the factory for maintenance and calibration; the instrument replacement sensor no longer needs to be disassembled like the traditional model The machine is returned to the factory for replacement. Anti-magnetic interference: It can resist 15V/meter strong magnetic interference. The national standard requirement is 10V/meter, which is 1.5 times better than the national standard. In areas where strong magnetic products are concentrated or electronic products are concentrated, such as tunnels, mines, confined spaces, etc., data is guaranteed to be stable and reliable. Imported high-precision sensor: standard infrared remote control, can realize alarm point setting, zero calibration, address modification without opening the cover, compatible with various control alarms, PLC, DCS and other control systems, realizing remote monitoring and explosion-proof Design, fast and stable, explosion-proof grade is Ex dIICT6, protection grade is IP65 Data transmission diversity: standard 4-20mA current signal, RS485 digital signal, 1 set of relay signal output. Optional 2 sets of relay signals (optional), optional GPRS wireless transmission function, provide SMS reminder function (optional), built-in wireless module, upload data to the Environmental Protection Agency platform or other platforms, and transmit signals without distance Limitations (optional)., Manufacturer: ZXZZAS
