Product Introduction
Application
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.

Anchor dynamometer working principle
Anchor dynamometer dynamometer steel cylinder in uniform with a few sticks vibrating wire strain gauges, when the axial load of the steel tube deformation, strain gauges with steel cylinder generates synchronous deformation, deformation of the vibrating wire strain gauges produce stress, thereby changing the vibration frequency of the vibrating wire. Vibrating solenoid excitation and measuring the vibration frequency, the frequency signal via cable to the reading device, you can measure the deformation caused by the force of steel tube should be variable substitution calibration factor can be calculated anchor dynamometer perceived value of the load .
