Product Name: CST1 Ultrasonic Lossless Detector Introduction: 1. Theory: Ultrasonic is easy to be reflected when it contacts to two different kinds of medium interface. 2. High-speed collection chip to lead to 240MHz collection speed. 3. Automatically inspect probe zero point, sound velocity, k value and generate DAC, AVG curve, then generate a report through inputting industrial inspection standard. Technology parameters: 1. Frequency range: 0.4~20MHz 2. Gain range: 0~120dB, 0.1, 2.0, 6.0dB stepping. 3. Dynamic range: 32dB 4. Vertical linearity: < 2.5% 5. Horizontal linearity: < 0.1% 6. Scanned area: 0~6000mm 7. Resolution: > 45dB 8. Surplus sensitivity: > 62dB (deep 200mm Φ2 flat-bottom hole) 9. Attenuator Accuracy: < ± 1dB/12dB 10. Working mode: single probe, double crystal probe, penetration probe. 11. Damping: 50/100/400Ω auto match. 12. Digits inhibition: 0~99% Linear inhibition, no influence to linear and gain. 13. Alarm: buzzer, LED light.
