Scope
Scope: This document specifies the models, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of mine-used intrinsically safe disc-type gate gap alarms (hereinafter referred to as "alarms"). This document is applicable to mine-used intrinsically safe disc-type gate gap alarms. Main technical content: When any gate gap reaches or exceeds 2mm, the passive contact is conductive, and the alarm device issues a red light alarm. The light alarm signal can be seen 20 meters away in the dark; it operates stably; and it complies with the provisions of GB 3836.1 and GB 3836.4 for explosion-proof devices. It can operate normally in an environment of 0~49℃.
