VTSYIQI Foundation Pile Dynamic Detector Reflected wave method Two channel

VTSYIQI Foundation Pile Dynamic Detector Reflected wave method Two channel About this item ◆ Basic Principle:Hit the top of pile with testing hammer to produce stress wave, and the wave may reflect when it meets defect (pile bottom, crack, or soil middle layer) while it run downward through the concrete. The probe placed on the top of the pile receives the reflected signal. The instrument digitally processes the signal in order to judge the quality of foundation pile. ◆Basic Principle:According to the time interval between the arrival of the direct wave and first reflected wave, or time interval between the two continuous reflected waves, the depth of foundation pile can be determined by the following equation: D= V P ×T P /2 (D - depth of foundation pile, V P – compression wave speed, T P － compression wave spread time) ◆Features:Two-channel design can measure reflected wave speed accurately, and it can collect reflected wave at two places. True 24 bit A/D data acquisition provides high resolution waveform avoiding the noise and signal distortion .High Brightness and TFT colorful LCD screen. ◆Features:1MHz high-speed data acquisition makes the minimum sampling time resolution reach 1us, providing more useful information and contributing to the discovery of shallow defects.Store waveform images for each tested pile. Water-proof; protection class reaches IP65. ◆Features:New wavelet processing method can effectively judge the integrity of foundation pile in complex situation. Key and touch screen Field of UseThe Foundation Pile Dynamic Detector is used to assess the integrity of concrete pile and identify the extent and location of the pile defects by using reflected wave method.It can be used for testing bored concrete pile and hammer pile and also for testing the structures with exposed top surface such as pillars.Technical parametersControl Mode: A8 Embedded platformScreen :5.7 inch、High brightness, TFT color LCD screenData Storage: ≥4GBOperation Mode: key+touch screenSentinel magnify (time): 1、2、5、10、20、50、100 adjustableA/D resolution (bit): true 24 bits A/DSampling time intervals(μs) :1～64000 adjustableMax length of sampling: 4096Trigger :Signal trigger,Noise voltage of the system (mV): ≤1Dynamic range（dB）:≥184Amplifier frequency range（Hz）:10～10kMax storage length :4096Amplitude nonlinear degree: ≤10%Time value error: ≤1%Time resolving power（us）:1Gain error（dB）:≤1Continuous working time(h): >5Number of channels :2Interference between the channels: ≤1%Transducer/Probe Sensitivity（acceleration mode）（mv/g）:≥100Frequency range of Probe（Acceleration probe） （Hz）:0.5 ~ 9000Transmission port: double USBWi-fi: yesPower:Built-in :batteryOutside :220V AC/DC
