TM-FAST offers, in its WL range, a wireless instrumented screw integrating the sensitive element (strain sensor) in the screw head and a measurement conditioner (memory and measurement). This version named WL integrates an NFC chip on the head of the screw to recover the power supply of the reader during a reading. An application developed for this purpose can read the digital value transmitted by the conditioner and converts it into Load.
The strain sensors can be applied to monitor strain changes in various structures for a very long period of time. The TM-FAST-WL has been designed for preventive maintenance but also one-shot measurements.
Strain sensors use the sensitivity of gauges to measure the intensity of tensile effects on the screw. The gauge is fixed inside the screw head minimizing the degradation of the mechanical strength of the screw.
