Project Overview

The solution for bolt stress detection is to study the relationship between bolt axial force and the rate of change of ultrasonic propagation time. By using the time of ultrasonic emission and reception to measure the tightening axial force of bolts, it can meet the fast and accurate requirements of customers for bolt stress detection

Features

◆ Fast detection speed, the probe can be directly placed at any end of the bolt for direct reading, which is faster and more convenient compared to torque wrenches

◆ Flexible to use, ultrasonic equipment is compact, portable, and energy-saving, relying on portable small capacity batteries to work for a long time

◆ Reliable testing, torque wrenches may be affected by friction caused by rusting of nuts and screws when testing fastening force, resulting in inaccurate measurementsUltrasonic stress testingThe instrument directly reads the comparison value between the sound velocity difference caused by stress changes inside the bolt and the standard model, with higher accuracy than torque wrenches

Recommended Configuration

◆ Instrument: HS-BLT

◆ Probe: Stress detection dedicated probe

application
