LKUT920数字超声波探测器的缺陷

LKUT920 ultrasonic detectors English display, master-slave type menu, and design have shortcut keys and digital shuttle spinning wheel, convenient operation. High-performance security battery modules facilitating disassembling and independent charging, large capacity high-performance lithium ion battery module that instrument continuous worktime reach eight hours, instrument light and small ,portable, and durable, one hand can be controlled, lead the industry trend. Wavepeaks memory: real-time retrieval defects peak, record the defects maximum value. Φvalue calculation: straight probe forgings detection after capturing pinpoint the highest wave, it automatically calculate, display defect equivalent size. Defect location: real-time display defect levels, depth (vertical) and acoustic distance position. Defect quantitative: defect equivalent dB value real-time display. Defect qualitative: according to the echo envelopment waveform, convenient artificially experience judgment. Surface modification: used for curved surface detection, can real-time display the defects circumferential position. DAC/AVG: curve automatic generation, sampling points without restriction, and can compensate and correct. Crack measurement height: endpoint diffraction wave automatic measure, calculate the crack height. Continuous record: real-time recording waveform, storage, playback. Waveform freezing: freeze the screen waveform, facilitate defect analysis. Type B scanning: real-time scanning and cross section shows, it can display the workpiece defect shape, make detection results more intuitive. Main Technical specifications: Detection range: (0 9999) mm Working frequency: (0.5 15) MHz Velocity range: (1000 9999) m/s Dynamic range: >= 32dB Vertical linear error: <= 3% Horizontal linear error: <= 0.2% Resolution force: > 40dB (5P14) Sensitivity allowance: >60dB (deep 200mm diameter 2 Flat-bottomed hole) Digital rejection: (0 80) %, do not affect the linear and gain Electrical noise level: <= 10% Probe types: straight probe, oblique probe, double crystal probe, penetrate probe. Sluice gate: into wave, lost wave; Single readings, double readings. Alarm : bees alarm, LED lamp alarm. Power source: (DC) 9V; Lithium battery for eight hours Envelop dimensions: 263 *170 * 61 (mm) Environmental temperature: (- 10 50) °C Relative humidity: (20 95) % RH. Note: the above indexes in the probe frequency is 2.5 MHz, detection means is under circumstances of whole wave.
