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.

KWT1S55 is a small range and high-precision tensile and compressive force sensor. Its main body is designed with an aluminum alloy structure, and its top is equipped with a compressive loading head, which is convenient for customers to apply pressure to the heart.

KWT1C80/130 series is a kind of column structure load cell, which both sides designed with double flanges to locating the position of mounting. The middle of load cell adopts through-hole design to meet the special requirements in the use process. This series has two size, the diameter of KWT1C80 is 80mm, the range is 25kN to 50kN, the KWT1C130 is 130mm and its range is 100kN. We also support customization on size and range as your needs.

1. Alloy steel/Stainless steel;

The KWT1C35 is a large-capacity, compact design pull-and-press column sensor with a special mounting end face design that enables the sensor to meet the tensile-compression direction loading during use. Using 17-4PH as raw material, rated capacity of 20kN, with high durability and excellent accuracy.

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.

1.Made of stainless steel.

2.Laser welding sealing treatment, can be anti-oil, waterproof, anti-corrosive gases and media.

This column sensor has the advantages of low height, large contact area, high comprehensive accuracy and convenient installation. Different measuring ranges and sizes can be customized.
It is mainly used in various electronic weighing equipment and tensile force detection equipment with large stress area, such as press-fitting equipment, mobile phone assembly, small pressure platform,
testing machine, press-fitting machine, oil press, cold and hot press, electronic hook scale hopper scale, etc.

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 is made of high-quality alloy steel, offering excellent stability and resistance to signal interference. It can be installed in confined spaces and customized to specific requirements, making it widely used for pressure and force measurement in various industrial applications.
