This is a linear displacement transducer integrated with a vibrating wire sensor that converts mechanical displacement to an electrical frequency output. This output can be transmitted over long distances and read or logged by remote digital readout unit or a data acquisition system.
The sensor can be used in different other instruments like uniaxial joint meters, triaxial joint meters, crack meters, borehole extensometers, soil extensometers etc.
