T-REX Incremental Extensometer
The T-REX incremental extensometer is used to measure the position of magnetic rings set along the axis of inclinometer casing. Measurements are later used to calculate changes in position, which indicate displacement. The system is mainly composed by T-REX digital probe, B.R.A.IN bluetooth reel with control cable and APP compatible with Android and iOS mobile operative systems. The
electronics’ readout is integrated into the reel and the BLE (Bluetooth Low Energy) wireless protocol permits a fast and safe
communication.
