The CTS-1200BM Bolt Preload Electromagnetic Ultrasonic Testing System is a portable device specializing in the preload force measurement, based on the acoustoelasticity effect. The system employs Electromagnetic Ultrasonic Dual-wave Testing Technology (the time-of-flight ration of a longitudinal and a transversal ultrasonic wave), which has an access to conduct in-situ preload force measurement of high-strength bolt. This instrument is able to carry out a non-contact inspection, which is with minimum surface preparation and no couplant required. It is easy to use and conducts measurements with fast and high accuracy, being free from the influence of the couplant. The CTS-1200BM is widely used in the measurement, acceptance and routing inspection of the in-service high-strength bolts preload in the industry of wind & thermal power generation, bridge construction, railway construction, etc.

Calibration
● Able to calibrate single or multiple bolts
● The software will automatically create the bolt calibration coefficients map
Bolt Preload Force Measurement
● Automatically measure bolt preload force, achieving the real-time display of pretension values and time-of-flight values.
Dual-wave Method in Electromagnetic Ultrasonic Inspection
● No need to know the length of the bolts
● Carry direct preload force measurement on the in-service bolts, with easy operation and high accuracy.
Auto Wave-searching
● Supporting auto longitudinal & shear wave searching and auto time-of-flight value calculation.
● Supporting manual measurement
Routing Inspection
● Achieving the comparison of historical waveforms (the display of the Preload Force )
Data Storage & Playback
● Supporting the storage and playback of measurement data for check
Auto-calculating Temperature compensation
● Supporting auto calculation of the temperature compensation coefficient according to the measurement result in different temperature
Freeze Screen
● Able to freeze the screen to capture the current displayed data
Data Analyze
● Auto Radar Map: After parameters of the upper and lower limit of the axial force are set, the device will automatically identify the serial number the bolts and the amount of the bolts which are out of limit range
Auto-generated Report
● After the inspection is done, the result can be generated on-site with no need to export to the computer for analysis
