HR-KFY dust concentration analyzer adopts the world's most advanced laser measurement principle of space inhalation dust, developed and produced by our company. Unique circuit design, the application of the latest devices, stable collection of dust content in the space. The maximum performance ensures the real-time monitoring and elimination of safety hazards in the production process, which improves the safety and stability of production.
The product is widely used in production workshop, tunnel, construction site, warehouse, storage yard, belt and wind feeding and other dust-producing working environment.
Product characteristics
The dust concentration is measured by the principle of space suction dust laser with high precision.
Non-contact measurement, high sensitivity, no dust contamination problems, higher reliability.
Integrated structure, long distance current signal transmission, strong anti-interference ability.
24VDC power supply, a variety of output signals to choose from (4~20mARS485 switching).
The internal MCU has the function of self-calibration, which automatically eliminates the influence of zero drift and ambient temperature on it.
Equipped with a drainage system, dust through the fan drainage to the laser detection point, further improve the accuracy of detection.
Equipped with 3 relays, as an output switching signal, each can be configured independently.
Installation position with multiple options, flexibility, no pipe restrictions.
Convenient user access and control management, can be linked with a variety of equipment (dust, spray, ventilation equipment).
