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.

Column type, hermetically sealed structure, IP68 compression, fast response, strong anti-overload, upper ball head load bearing.

Simple install, easy to use, suitable for electronic truck scale, dynamic railroad scale and big capacity hopper scale, etc.

KWT1D52H is a big-range compact-design column load cell. It is made of 17-4PH material, and its rated range is 200kN. The sensor has a rasied surface radius to reduce the possibility of off-center load.

• Capacity: 0-100T
• Sensitivity: 1.5±0.05mV/V
• Non-linearity 0.1% F.S.
• Repeatability 0.05% F.S.
• Material Aluminum alloy with nickel plated
• Bi-directional tension and compression
• Can be customized

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.

This product has a simple structural design and low cost. The design of its sealing membrane changes the cumbersome process of requiring a matching housing in the past, overcomes the defect of the housing of traditional sensors being easily damaged due to deformation, and greatly improves the sealing performance of the sensor. Compared with traditional column sensors, this type of sensor achieves relatively high accuracy in linearity, lateral resistance, torsion resistance, and azimuth error.
Traditional column sensors are widely used in various electronic weighing devices such as track scales, hopper scales, platform scales, etc.
