GRG5H Infrared carbon dioxide sensor
This sensor adopt international advanced Nondispersive infrared detection technology, overcome the defect of Thermal catalytic principle sensor short Cyclicality ,Easy to poisoning ,and Using the embedded microcontroller controller technology ,Built-in precise temperature compensation circuit make the detection precision won’t be affected by temperature variation ,this sensor has the features of measuring precision/quick response /long Calibration cycle /not affected by other gases/Wide measuring range/low power dissipation/long service life
/stable performance/high reliability . This sensor can install working palce by remote-control unit conveniently,meantime output 200~1000 hertz frequency signal and RS-485 digital signals ,easy to suit with all kinds of Coal mine safety monitoring system。
Mainly used for continuous gas concentration measurement in gas explosion environmentsuch as underground drilling work face,return aircourse,Mechanical and electronic chamber .this sensor has the function of determining and display instantaneous concentration/Over-limit alarm /output Power control signal/Power control signal/digital communication
