GOWORLD CTS-8682 Ultrasonic Pre-amplifier for flaw detector TOFD air-coupled ultrasound electromagnetic concrete UT CT
The CTS-8682 is an ultrasonic pre-amplifier with mini size, low noise, wide band and high gain, based on unique patented technology of the Goworld. Suitable for TOFD, air-coupled ultrasound (empty coupling), electromagnetic ultrasound, concrete, ultrasonic CT, etc., which require sufficient gain or increase the broadband signal-to-noise ratio to achieve optimized echo.
- Light and handy, only 90mm×55mm×23 mm in size, water- and dust- proof.
- Low Noise, Wide Band, High Gain, and Hi-Fi.
- Protection from H-Volts on Input & Output Circuits and Prevention from Mis-plugging.
- Power-shift technique by monocell, allowable for outsourced power supply or recharging.

Applications:
1.Supply of more gain or elevation of wide-band SNR in order to optimize echo-acquisition field.
2.Elevation of SNR during inspection on materials thick and causing high ultrasonic attenuation and scattering, like nodular cast iron, austenic steel, brass, bronze, rubber, fiberglass or some kind of composites.
3.Compensation for amplitude loss due to transmission through long cable between probe & instrument. Improving SNR of long-distance transmission.
4.Preamplification on diffraction signals of "tips" during TOFD inspection.
5.Preamplification for EMAT inspection.
6.Preamplification for inspection on front pile of concrete
7.Preamplication on elastic modulus measurement of rock or ore, acoustic scattering from bubble of water, other kind of liquid or plankton, and even biological tissue analysis.
8.Measurement on motives in the industry involving oil gas, rock and mineral, propagation signatures of seismic wave and ultrasonic velocity testing for seismic parameter relations.
9.Preamplification for acquisition of AE signals.
