The GCG1000 dust concentration sensor can directly read the mass concentration of dust particles in the air. The sensor according to MT163-1997 "direct reading dust concentration measuring instrument general technical conditions" and Q/320581ESD001-2008 "ZGGCG1000 type dust concentration sensor" enterprise standard and GB3836.4-2000 standard ExibI protection grade design, absorbing the dust of advanced technology at home and abroad, to detect the dust by the light refraction principle, by the microprocessor test data on the operation display the dust concentration and converted into a data signal output, for the use of mine monitoring system or other control system. The sensor is composed of a sampling head, a detection device, a single-chip microcomputer system and an exhaust system. It has the characteristics of convenient carrying, fast and accurate measurement, high detection sensitivity, stable performance and simple maintenance. Because of the use of laser technology and high reliability pumping system and other new technologies, the sensor has more quality and better technology.
The application range of GCG1000 dust concentration sensor:
It is suitable for continuous monitoring of the concentration of total dust in the atmosphere in the coal mine and other operating environment with explosive danger. It can accurately and timely reflect the pollution of dust in the dust operation place.
