YHU260 top and bottom plate moving close dynamic alarm device

The roof and floor movement dynamic alarm instrument (also known as the roof dynamic instrument and the roof dynamic alarm recorder) is an intelligent instrument used in coal mines to accurately detect changes in the roof separation layer of tunnels. It has the characteristics of easy operation and intuitive display. In particular, this product adopts an improved battery power supply system, which greatly improves the reliability of the instrument and the service life of the power supply. It can be used underground for a long time without maintenance. It is a traditional mechanical Ideal replacement for roof dynamometers. Mainly used for dynamic monitoring, display, storage and real-time data transmission of roof and floor in coal mines. It can also be used to monitor roof subsidence in culverts, tunnels and other places,
