1in Linear Variable Displacement Transducer

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 0–1in (0–25.4mm) displacement range.

HM-740 has a 0–2in (0–51mm) displacement range.

Features:

• An optimal solution for digital displacement measurement of soil
• Repeatability to 0.002mm
• The industry-proven double bearing system reduces side load errors

Included Items:

• 1in or 2in Linear Variable Displacement Transducer

• Dial Indicator / Displacement Transducer Brackets for positioning the LVDT
• Data Acquisition Software records specimen and real-time test data for a wide range of soil laboratory tests and prepares reports following applicable ASTM and AASHTO requirements.
• Data Readouts display electronic measurements on two or four channels from Load Cells and Displacement Transducers.
