ZT-205Crack depth detector
Application scope:
The crack depth gauge is used to measure the depth of cracks on the surface of concrete.
According to the standard:
Technical Specification for Ultrasonic Testing of Concrete Defects CECS21:2000
ZT-205Crack depth detectorProduct Features:
Easy to operate: Chinese menu, test upon startup, simple buttons to complete the test.
Intuitive results: No need to measure wave velocity, no need to calculate, directly display crack depth.
Data processing: The data can be transmitted to a PC for quick printing of detection data.
ZT-205Technical Specifications:
1. Crack depth testing range: ≤ 500mm
2. Test error ≤ 5mm or 5%~10% of actual seam depth
3. Test data storage capacity: 25000 test data
4. Data transmission interface: USB
5. Power supply: rechargeable battery, with a power supply time of up to 50 hours
6. Host volume: 220 * 162 * 91mm
Comparison of crack depth detection methods:
Test steps |
test parameters |
Ultrasonic flat measurement method |
Crack depth gauge |
1. Non cross seam testing |
Sound velocity measurement |
When measuring sound at L=100, 150, 200, 250, 300mm..., calculate the sound velocity |
No need |
2. Cross seam testing |
When there is a sound of crossing the seam |
Measure the sound when crossing the gap L '=100, 150, 200, 250, 300mm |
Measure the diffraction wave vibration signals of L '=0, 5, 10, 15, 20mm |
3. The results show that |
Crack depth calculation |
According to the formula, use a computer indoors to select data and calculate depth |
No calculation required, crack depth displayed directly on site |
The testing surface requires |
Seamless and cracked areas with a length of no less than 300mm are required for testing |
No need for seamless zone |
|
Need to test length |
L and L 'should be at least 300mm |
L '=1.5 times the depth of the crack |
|
Requirements for testing personnel |
Instrument operators and data processors require basic professional and computer knowledge |
General technicians can operate independently by referring to the instruction manual |
