Displacement Transducers (VW) | Model 4450

  • Model 4450 Displacement Transducer (50, 100 and 200 mm ranges).
Model 4450

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.
