Bolt preload force sensor is a device used to measure and monitor the axial preload force of bolted connections. It can be used to improve the reliability and safety of bolted connections, preventing bolts from loosening or becoming too tight. It can reflect the contact interface stiffness and clamping force of bolted connections, and detect or quantify the degree of bolt tightening. The inner hole size can be customized according to non-standard specifications.

This product is simple in structure design and low in cost. The design of its sealing diaphragm changes the complicated process of matching the shell in the past, overcomes the defect that the shell of the traditional sensor is easy to be damaged due to deformation, and greatly improves the sealing performance of the sensor. Compared with the traditional column sensor, the sensor with this structure has higher accuracy in linearity, lateral resistance, torsion resistance and azimuth error.
This small size is suitable for the production and testing of 3C digital products. Traditional column sensors are widely used in various electronic weighing equipment such as track scales, hopper scales and platform scales.

Widely used in auto press assembly, automated assembly, 3C product testing;
New energy product assembly, medical testing, robot, mold assembly and other industrial test, measurement and systems.
