The patented Inductosense technology, known as the 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 handheld 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 the thickness of the structure.
WAND Evaluation System
The WAND Evaluation System is designed for ultrasonic thickness measurements and monitoring internal corrosion or erosion on pipework and structures. The system has the following advantages:
The WAND sensors can be permanently attached to structures enabling repeatable, accurate measurements from exactly the same location without human error. Over time erosion/corrosion rates can be accurately determined.
The WAND sensors are battery-free, wireless and compact (<1mm thick). They can be attached to structures underneath coatings, insulation or composite repairs. This alleviates the need to remove the outer layers from the structure in order to make an inspection.
An ultrasonic thickness measurement can be taken in less than a second by bringing the probe near to the WAND sensor and pressing a button. There is no need to use coupling gels or accurately align a probe.
