H2S gas detector explosion proof fire safety disaster prevention security equipment
Key Specifications
YA-D 300 point gas detectors are widely used in chemical, petroleum, metallurgy, liquefied gas stations, painting operations, gas transmission and distribution and other toxic and flammable gas production, storage, use and other indoor and outdoor dangerous places.
The product adopts wall-mounted (can also be tube-mounted, bracket, and ceiling-mounted) installation, and is used in conjunction with the controller to process various data uploaded by the gas detector through the controller's single-chip microcomputer, and finally Complete data display, output control and other functions. Features
☆Display the concentration of the detected gas.
☆Fault alarm, high and low alarm.
☆Field screen display, including backlight, the characters are larger and clearer, and when the device alarms, the backlight turns red.
☆Infrared remote control input, no need to open the cover, more convenient.
☆Support three different sound and light outputs, corresponding to fault,low report and high report respectively.
☆Zero adjustment, calibration and test functions.
☆Output DC4-20mA standard signal.
☆Support485, two bus, LoRa, flexible and changeable communication methods.
☆Equipped with high-performance ARM microprocessor for easy operation.
☆Three-way relay (250V5A) output, automatically open the fan and solenoid valve.
☆It can store40 high and low alarm records in a cycle.
☆The toxic gas detector can realize the conversion between mg/m and μ mol/mol. Connect the controller to the gas detector equipment, turn on the power after confirmation, and the gas detector will display the flammable gas sign, relay status, detection concentration value and the percentage of the current concentration in the range, the normal light is on, and the detection starts. When the gas concentration is higher than the set concentration, the alarm will sound, the alarm LED light will be on,the alarm light will flash,and the sound can be cleared by pressing the mute button. When the gas concentration is lower than the set concentration, the alarm will turn off the alarm sound and the LED light will go out.
