Sensor integration
Sensorise SmartScrews are standard screws or bolts with a sensor wire, as thin as a hair, integrated into the base of the thread. This patented method utilizes existing tolerances and does not weaken the fastener.
SmartScrews exhibit the same mechanical properties as standard screws and bolts.
Strain measurementThe basic mechanism relies on changes in the electrical resistance of the sensor wire. When tightened, the screw elongates, and its circumference decreases. This compresses the sensor wire, thus decreasing its electrical resistance.
SmartScrews are electrically equivalent to a Wheatstone bridge and compatible with most industrial signal conditioners.
