Electromagnetic Ultrasonic Bolt Axial Force Tester
Code: UFT-Q100
Primarily applied in wind power, oil and petrochemical, nuclear power, hydrogen energy, heavy industry, and other sectors
Perform quality inspections, risk assessments, inspection-based maintenance, leak detection and etc. on flange bolts
The dual-wave method measurement principle for transverse and longitudinal waves enables direct measurement of the absolute axial force of in-service bolts without requiring measurement of the bolt's initial length
Unlike piezoelectric ultrasound, no grinding, no coupling, no patching, making operation simple and convenient
Enter bolt specifications for quick measurement of bolt axial force

FAQ
Do I need to grind, apply couplant, or patch the bolt surface before measuring?
No. The UFT-Q100 uses electromagnetic ultrasonic measurement, so no grinding, couplant, or patching is required. Simply enter the bolt specifications and start measuring — each bolt takes only 4–10 seconds.
Can it measure bolts that are already in service, without knowing their original length?
Yes. The UFT-Q100 uses the dual-wave method (transverse and longitudinal waves), which enables direct measurement of the absolute axial force of in-service bolts without requiring the bolt's initial length — ideal for flange bolt inspection in wind power, oil & gas, petrochemical, nuclear power, and hydrogen energy applications.
How is measurement accuracy ensured, and can results be exported for reporting?
INSIZE offers a calibration service — send bolt samples in, and once calibration is complete, load the calibration file into the device for accurate axial force measurement (±5% after precise calibration). The device also stores calibration data for different bolt grades, automatically saves measurement results, and exports reports in Excel, radar chart, and statistical chart formats.
