GCG1000 type dust concentration sensor
One, overview
1 product features
GCG1000 type dust concentration sensor is based on the MT163-1997 "direct reading dust concentration measurement instrument general technical conditions" and Q/LGKJ003-2009 "GCG1000 type dust concentration sensor" enterprise standard and GB3836.4-2000 standard Exib I intrinsically safe level design. Products absorbed dust of advanced technology at home and abroad, using the principle of light scattering, mass concentration of dust in the air in direct detection, through digital tube display in the field and converted into frequency signal output, can be used for coal mine safety monitoring system or other measurement and control system. The product has the features of fast and accurate measurement, high sensitivity, stable performance, can be preset K value, direct display and output the dust mass concentration.
2 the main purpose and scope
Continuous monitoring of GCG1000 type dust concentration sensor is widely used in the workplace dust exist flammable explosive gas mixture in the work environment, environmental monitoring is also suitable for other public places.
3 the use of environmental conditions
The sensor should be able to work normally under the following conditions:
Temperature: 0 ℃ ~ 40 ℃
Relative humidity: ≤ 98%
Atmospheric pressure: 80kPa ~ 116kPa
Containing gas or coal dust explosion hazard in the pulp.
