Welcome to the official website of Qingdao Huanrui Automation Technology Co., Ltd!
The unique circuit design and the application of new devices stably amplify very weak charge signals at high magnification, ensuring online continuous measurement of spatial dust concentration.
Space dust meter with laser method HR-KFY
The HR-KFY measuring the airborne dust with highly sensitive and non-contact which based on the advanced laser measurement principle of spatially inhaled dust,will get the spatial dust concentration value though a high-precision laser dust detection sensor.This meter is real-time monitoring and elimination the safety hazards in the production process, will improves the safety and stability of production.
1\Determine the dust concentrations with highly accurate which based on the laser principle of space inhalation dust
2\Non-contact measurement with high sensitivity,without dust contamination problems and higher reliability
3\Transfer the current signal in long distance with high anti-interference capability due to Integrated structure,
4\Power supplied by 24 DC and multiple output signals are available (4~20mA/RS485/switching)
5\The internal MCU is self-calibrating,can automatically eliminating the effects from zero drift and ambient temperature
6\The meter equipped with a diversion system, diverting the wind and dust by a fan to the laser detection point,improved the accuracy of the detection substantially
7\Equipped with 3 relays as output switching signals, each relay can be configured independently.
8\ RS485 communication interfaces and 1 4~20mA output interface are reserved
9\ Reserved RTC clock
10\Three panel indicator
11\Versatility and flexibility of installation position, no duct restrictions
12\Easy access and control management, linkage variety of equipment (dust reduction, sprinklers, ventilation equipment)
Match to variety of industrial applications,Including: production workshops, tunnels, construction sites, warehouses, coal mines, stockyards, materials by wind-fed and belt, and other dust generating environments(steel making, power generation, petroleum, chemical, pharmaceutical, building materials processing, coal mining and mining, cement manufacturing and packaging industries).Such as Bag filter bag breakage detection, or powder material recovery, total delivery monitoring, or all type flue dust emission concentration monitoring from boilers
