GCG1000 dust concentration sensor

GCG1000 gauge sensor dust sensor dust concentration use of the product assimilate the advanced technology of measuring dust can continuously detect the concentration of flammable gas mixture explosive environment in the presence of floating dust, with fast and accurate measurement, high sensitivity, LED display, remote signal transmission, stable performance, can be preset K value, and other functions and features can be used with a variety of supporting the use of monitoring systems. Features sensors continuously for a long time to real-time display of coal mine dust concentration, while the frequency of the signal output 200-1000HZ and mine monitoring and control system to adapt and 4-20mA current signal for the mine monitoring system or other systems. By pre-warn dust concentration threshold point, when the dust concentration measured reaches the value immediately outputs a warning signal to alert staff to promptly initiate appropriate dust control measures. If the microcomputer intelligent spray device connection, enabling measuring dust spray function.
