Fully automatic high-strength bolt detector

This detector is designed and manufactured in accordance with the requirements of the "GB50205-2020 Code for Acceptance of Construction Quality of Steel Structures". It can detect, display, and print the axial force, torque, and torque coefficient of large hexagonal high-strength bolt connection pairs (M16, M20, M22, M24, M27, M30). When the axial force reaches the standard value, the detector emits a buzzing sound and records the detection data. After the device stays for 1 second, it automatically reverses and releases the sample. At the same time, the detector automatically calculates the torque coefficient based on the detected axial force and torque and displays it automatically. After a set of tests is completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation of N specimens. The control system can update and store 32 sets of data in a cyclic manner, and can read and print them at any time.
