TERI is developed to be applied in the civil aviation and is intended for the impedance express testing of multilayer soldered, bonded composite materials and honeycomb constructions in order to detect such defects as discontinuities and disbonds. TERI relates to the indicator devices and is not a measuring tool. TERI impedance express tester is a simplified modification of the device DAMI-C. It is fully compatible with the applied materials and probes.

 Functional capabilities

TERI provides the impedance, amplitude-phase acoustic testing method in the frequency range from 8 to 12 kHz , using the dry point contact by one-sided access.

TERI enables to determine the relative value of local impedance in the test point. It allows to indirectly estimate the sheet material thickness. There is the complex plain mode, displaying the friction noise zone. It provides better opportunities to adjust the device for different roughness of the testing object surface.

The device is equipped with the probe PADI-8-02. The probe has small dimensions. It allows its using for the inspection of hard-to-reach places.

The device is easy-to-use and easy-to-adjust. While operating the device under field conditions, it is often necessary to alter the material types. For this reason, the adjustment must be maximally simple and take a little time. The adjustment of TERI is fully automated. Just place the probe on the defect-free area. The device will set the necessary threshold value of defect alarm activation. Except, there is a possibility of manual adjustment. While operating, the device is fixed to the operator`s hand with a strap. It increases the mobility and operating convenience.

TERI is applied in the civil avaiation as an up-to-date alternative of obsolete procedures, requiring the mechanic knocking of honeycomb constructions with "hammers". The new technology increases the testing reliability. For the civil aviation, there is the special non-reference adjustment that considerably increases the testing reliability and enables to have much lesser number of test blocks.

TERI impedance express tester is recommended to be applied in civil aviation.
