GJC4 type gas sensor methane sensor

GJC4 type gas sensor methane sensor gas sensor sensor gas sensor gas sensor methane sensor Jinan, China Coal Mining Equipment Co., Ltd. is a professional manufacturer, good product quality, service and good attitude, delivery speed, you are welcome to establish long-term partnership . Product Knowledge gas sensor is a volume fraction of the gas converted to the corresponding electrical signal converter. Gas sensor probe through the sample gas conditioning, typically include filter out impurities and interfering gases, drying or cooling process instrument display section. Methane sensor is to meet the needs of our monitoring of underground coal mine methane and developed. It can continuously and automatically converts underground methane concentration into a standard electrical signal transmission to the associated equipment, and has a local display of methane concentration, overrun sound and light alarm off function after national explosion-proof verifying authority for online testing, can be used with all types of domestic monitoring system and power meter, gas locking device supporting wind power, suitable for stationary use in the coal mining face, electromechanical chamber, back to the wind tunnel and other locations . The main technical indicators 1. Measuring range (0 to 4)% 2. Range 0  12 months 14. The continuous working time> 15h 15. Cable length <2000M 16. Protection class IP54 17.
