Introduction to the Anti-Slippage Coefficient Tester

This testing instrument is capable of conducting slip-resistance coefficient tests on large hexagonal high-strength bolted connections of sizes I16, M20, M22, M24, M27, and M30, as well as on torsional-shear-type high-strength bolted connections of sizes M16, M20, M22, M24, and M27, in conjunction with slip plates. It features four physical channels and six sets totaling 24 logical channels. The instrument also includes parameter backup and recovery functions and supports automatic calibration.

The instrument is equipped with a peak-hold function in accordance with the inspection requirements for high-strength bolts, and an RS-232 interface is provided to facilitate connection to a computer, enabling data transmission for further processing and subsequent printing of test reports (this feature requires special ordering).

Before using this instrument, please read the instruction manual carefully and ensure you fully understand its contents before powering it on. Handle the instrument with care and operate it correctly to maintain its high accuracy and optimal performance over the long term.

Introduction to High-Strength Bolt Detectors

The high-strength bolt testing instrument is capable of measuring the axial force, torque, and torque coefficient of large hexagonal-head high-strength bolt connection assemblies in sizes M16, M20, M22, M24, M27, and M30, with real-time display and printing. When the axial force reaches the value specified by the relevant standards, the instrument emits an audible alarm and records the test data; simultaneously, it automatically calculates the torque coefficient based on the measured axial force and torque and displays the result. Upon completion of a test group, the instrument automatically computes the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation for N test specimens. Users can input the test number, as well as the bolt model, grade, and specification. The control system supports cyclic data updating and storage, enabling on-demand retrieval and printing of test results.
