The EVOTIS is an automated tap tester that has been developed for use on thick structure components. Unlike the Woodpecker, it measures both the piezoelectric and acoustic response of the material under test, utilising directional microphones to ‘listen’ after the input of energy. Both results are shown graphically where thresholds can be set to a baseline value, giving a go/no-go device. The EVOTIS is used extensively by Japanese Rail to inspect their infrastructure.
- Advanced Tap Tester using the acoustic analysis method
- Two sensors (Piezo crystal and microphone) are used to capture responses from the solenoid-driven tapping device
- The software allows point measurements to be compared
- Potential to integrate with probe tracking and visualisation software
Features:
- Monitoring of acoustic response (microphone) & feedback from piezoelectric crystal integrated in the actuator
- Easy operation
- ON line mode:
- Quantitive & graphical display in real time
- Logging of values (export to Excel)
- OFF line mode:
- Export to .csv file for analysis
- Different frequency settings
- Examination possible in noisy environments
- Monitoring of acoustic response (microphone) and feedback from piezoelectric crystal integrated in the actuator
- Optional probe tracking & visualization (3D) software
Applications:
- Detection in: thick structural components (30 mm+)
- Detection of inserts & changes in the structure
- Marine: inspection of boded parts to include bulkheads, beams, hull/deck bond; currently being used to revalidate legacy lifeboats
- Offshore: inspection of skins, ribs & spar bonds to include lightning strike parameters of damage
- Civil: inspection for voids, ceramic tile bonds, material levels behind shuttering, concrete cancer, moisture damage
