Employing light scattering technology, the GCG-1000 Dust Concentration Sensor provides direct measurement of total dust concentration. Designed for permanent installation at industrial worksites, it features local data display while simultaneously transmitting either a frequency or RS485 signal (selectable) for compatibility with mine safety detection systems and monitoring networks. The instrument delivers rapid, accurate measurements with high sensitivity, operational stability, configurable scattering coefficients, and direct mass concentration readout. Primarily deployed in dusty environments including mines and cement plants for continuous airborne particulate monitoring, it supports both integration with safety monitoring networks and independent operation as a local display unit.
Product Features
The GCG-1000 Explosion-Proof Dust Monitoring Sensor incorporates advanced domestic and international dust measurement technologies to accurately detect the mass concentration of airborne dust particles. It offers multiple integrated functions: on-site concentration display via a digital tube, frequency signal output for integration with mine monitoring and control systems, and compatibility with explosion-proof power supplies for direct dust monitoring. When equipped with an explosion-proof alarm unit, it supports user-defined threshold settings for over-limit alerts. Furthermore, by connecting to explosion-proof substations and data acquisition systems, it enables bidirectional data communication between field devices and control terminals, facilitating flexible and user-friendly operation.
The system ensures rapid and precise measurements with high sensitivity, operational stability, and direct readout and output of mass concentration values. It is suitable for a broad range of applications, including continuous total dust monitoring in hazardous areas with flammable and explosive gas mixtures, as well as environmental monitoring in other public spaces.
The system delivers early-warning functionality in these flammable and explosive environments:
1. Metal Processing: aluminum, zinc, ferrosilicon, magnesium, iron powders; aluminum grinding dust
2. Grain & Food Processing: wheat, starch, sugar, milk powder
3. Feed Production: blood meal, fish meal
4. Agricultural Byproducts: cotton, tobacco, tea dust
5. Forest Products: wood dust, paper dust
6. Synthetic Materials: plastics, dyes
7.Coal & Mining: coal dust and other combustible particulates
