Description
Introduction
The GSH1500 sensor utilizes a highly reliable dual-channel self-adjusting Hallgear sensor, triggered by magnetically conductive material gears, to output asquare wave frequency multiplication signal. The product's exterior adopts afully sealed stainless steel structure, capable of meeting harsh working condi-tions such as moisture, explosion, corrosion, and dust resistance. lt is suitable forunderground coal mine environments with coal dust and gas explosion hazards.Explosion-proof type: Mine-used intrinsically safe type; Explosion-proof mark:ExiblMb.Explosion-proof mark : Ex dlMb.
