20t Hand Tension anchor bolt dynamometer used for coal mining    

Anchor dynamometer is used for long-term monitoring of hydraulic structures and other concrete structures, rock slopes, bridges and other state prestressed anchorage, and simultaneous measurement of buried point temperature vibrating wire sensors. There are two string anchor dynamometer. Three string Four strings and six strings. By vibrating wire frequency readout readout dynamometer each branch strain sensors in real time measurements and instrument parameters can be calculated using the pressure exerted by anchor.
