Contactless UT RFID
Wireless and Non-Destructive (WAND) system, consists of two parts – a compact, battery-free sensor and a handheld probe. The sensor is entirely passive and can be permanently installed onto a structure.
The lightweight probe powers up the sensor by non-contact inductive coupling when it is brought nearby (even if the patch is under material). The sensor then sends out an ultrasonic wave into the structure and detects the received signal.
This is then transmitted back wirelessly to the probe where the signal is analysed. For our internal corrosion system, the analysed signal provides structural thickness.
