1.A ring-shaped column sensor is a device used to measure and monitor the axial preload of bolted connections.
2.It can be used to improve the reliability and safety of bolted connections, preventing bolts from loosening or becoming too tight.
3.It can reflect the contact interface stiffness and clamping force of bolted connections, and detect or quantify the tightening degree of bolts.
4. The inner hole size can be customized non-standard, and the elastomer is made of high-quality stainless steel material.
