Dynamics of a Vibrating Wire Load Cell in Strata Measurement

As the name suggests, a vibrating wire load cell is an instrument that uses high frequency wire mechanism for measuring load-bearing force. When the load bearing force weighs down on the instrument the resulting impact causes tension on the wire which in turn, results in a change in its frequency. This change in frequency is the indicator of the load being measured; the measurement is usually accomplished with the help of a sensor that is integrated into the instrument.

 A vibrating wire convergence meter is a vital instrument for detecting any strata movement in the tunnel roof. The meter has three essential components e.g. the hooks that need to be fastened to the anchor points of the surface being studied; the vibrating wire unit which is part of the transducer and the connector rod assembly. Such a meter is vital for studying tunnel roofs inside a mine because of the steady strata movement.

The readout box is a critical part of this meter because it will give you the result of the examination you would be carrying out. For engineers in a mine this information is necessary to plan operations wherein the safety of the miners is given top priority.
