AirScope TT is a cost effective solution for those air-coupled applications that only need two transducers for through-transmission.

These systems are suitable for non-contact transducers with a frequency range between 20 kHz and 2.5 MHz.

AirScope TT includes a flexible software to easily configure different air coupled techniques (Plate wave, TT, etc).

Main applications:

o       Air-coupled NDT

o       Positioning systems

o       Acoustic Vision

o       Lamb waves

o       Structural Health Monitoring

Emitter:

-       Programmable pulse amplitude form -20 V to -400 V

-       Programmable pulse width from 200 ns to 25 μs, with resolution of 5 ns

-       Burst mode up to 256 pulses

-       Encoder trigger or external input signal trigger

Receiver:

-       Bandwidth from 20 KHz to 2.5 MHz (- 3 dB)

-       Programmable sampling frequency from 24.4 KHz to 25 MHz

-       14 bits A/D conversor

-       Programmable Gain  up to 100 dB

-       TGC curve

-       Attenuator -20 dB

-       Automatic start of the acquisition with programmable threshold (echo-start)

Signal processing:

-       EMI Filter.

o     Removes, in real-time, the impulsive noise

o     Improves flaw detection and reduces the production of false alarms

o     Keeps a high dynamic range in noisy environments for C and D-scans

-       Band-Pass filter with programmable cut-off frequencies.

-       Scan compression with Non-Peak-Loss compression algorithm, up to 128:1 compression rate.

-       Average (2, 4, 8, 16, 32, 64, 128, 256)

-       Programmable hardware and software gates to detect of the maximum, minimum, the first peak over the threshold, positive edge or negative edge

-       Acquisition information data in real-time: A-scan, B-scan, peak position and amplitude (gates), encoders count.
