T-REX is a removable extensometer which has been designed for incremental measurements along the axis of inclinometer casing equipped with targets. The T-REX probe is equipped with a contactless magnetostrictive linear transducer. Operating cable, placement rods, portable readout and T-REX analyzer software are provided. Utilization of the Archimede portable readout is suitable for tracking readings with T-REX probes. Through the USB port, the measurements can be easily transferred to a PC for data management. T-REX analyzer software allows the operator to computer displacement measurements line-wise per meter of distance, both in vertical and horizontal installations.

Technical specifications

T-REX extensometer offers several advantages:
-wide measuring range (±100 mm displacement every per meter) which allows applications either in soil or rock
-fully compatible with Sisgeo inclinometer operating cable, connector and readout
- no-mechanical contact between probe and targets
-combined with inclinometer measurements permits 3-D deformation borehole profile.
