Displacement Transducers (VW) | Model 4450

Model 4450 Displacement Transducer (50, 100 and 200 mm ranges).
  • Model 4450 Displacement Transducer (50, 100 and 200 mm ranges).
  • This modified 1800 telltale configuration uses a customized 4450 VW displacement transducer, magnetically attached to the telltale clip, that may be adjusted in three dimensions. Included is the 1450-7, 1450-8, and 1150-42X modified with a mild steel reference surface for magnetic attachment, and a 4450-1X-100MM modified with a magnet on the base and moveable handle to aid in positioning. The magnet has a maximum 23 lb. (10.4 kg) pulling force to prevent unintentional release from the reference surface. (Enlarged at right to show detail.)

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.
