Displacement Transducers (VW)

Overview

The Model 4450 Displacement Transducer provides remote readout capability for borehole extensometers. They are particularly useful where other types of vibrating wire sensors are used and/or for installations where long cable runs are required. The Model 4450 can also be installed between borehole anchors, in conjunction with the requisite length connecting rod, to provide a permanent, in-place incremental extensometer.
