Linear Variable Displacement Transducers (LVDT) precisely measure deformation or movement of soil samples during tests such as shear, consolidation, and triaxial. They provide a digital output related to the displacement of a reference surface. The linear displacement transducers feature anodized aluminum housing, stainless steel actuating shaft with an anti-rotation device, and include the industry-proven double bearing system on both the actuator shaft and spring to reduce side load errors. Each transducer has a repeatability of 0.002mm, and includes two fixing clamps, screws, and a gauging head with a hardened ballpoint.
HM-739 has a 1in (25.4mm) displacement range.
HM-740 has a 2in (51mm) displacement range.
