Vibrating Wire Linear Displacement Transducer

Linear Displacement Transducer

EDE-VXX linear displacement transducer incorporates a vibrating wire sensor that converts mechanical displacement to an electrical frequency output. This output can be transmitted over long distances. The sensor can be used in uniaxial joint meters, triaxial joint meters, crack meters, borehole extensometers and soil extensometers, etc.
The sensor is available in 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
Note: If purchase order does not specify, 'RC' version will be supplied.
