KRABO® technology embeds an integrated and fully wireless electronic system in the fastener to monitor bolt tension using the ultrasonic technique.
What is inside?
An ultrasonic transducer is connected to an electronic front-end specially designed to measure the bolt length with high resolution and high accuracy. The processor elaborates on the information and controls the device. A wireless communication module grants connectivity to the network. The energy storage contains all the power required for the operation, and an optional energy harvesting module can extend its life to the infinite.
