Vibrating Wire Displacement Transducers

Model EDE-VXX Overview

The EDE-VXX 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 Encardio-rite model EDI-51V remote digital readout unit or Encardio-rite model EDAS-10 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.

The sensor is available in the following variants:

  • EDE-VXX-SC with side cable (suitable for crack gage)
  • EDE-VXX-RC with rear cable (suitable for BHE)
  • EDE-VXX-WP waterproof
