Advantages

1. Adopting premium time chips to record the time taken between the ultrasonic signals emitted and recevied by the gauge.

 

2. These gages employ ultrasonic double-crystal probe with stainless steel housing, and it can effectively reduce clutter, sensitive, hard and durable.

 

3. Automatic Gain switchable to amplify the ultrasonic signal so that the emitted pulse is accurately captured by the transducer as it propagates, and obtains accurate data.

 

4. High precision ensures LS211 can pass Chinese authoritative metrology institute.

 

5. Built-in sound velocity of multiple materials including metallic(iron, copper, aluminum) and non-metallic materials(plastics, ceramics, plexiglass).

 

6. Built-in sound velocity of multiple materials.

 

7. Ergonomic design with durable rubberized grip.

 

Common applications for ultrasonic thickness gauges include

Inspecting pipelines and piping systems for corrosion and wear

01

Measuring the thickness of storage tanks and pressure vessels

02

Checking the integrity of structural steel and welds

03

Assessing material thickness in manufacturing processes

04

Measuring the thickness of ship hulls, aircraft components, and other transportation equipment

05

 

 

Measurement Method

Grid measurement method：Using an ultrasonic metal thickness gauge and point thickness measurement statistics in the grid-designated region. The monitoring of corrosion in high-voltage equipment frequently uses this technique.

 

30mm multi-point measurement method：The lowest value for the thickness of the metal being measured should be taken at a measurement site in the center of a circle with several measurements within a range of about 30 meters when the measurement value is not particularly steady.

 

Typical measuring technique：When the split surface of the probe is 90 degrees from one another during the two measurements, measure the thickness once with the probe and take the minimum value as the thickness of the metal to be measured.

 

Continuous measurement method：Continuous measurement using a single point measuring technique along the designated path with a maximum 5 mm measurement interval.

 

Precise measurement method：Around the designated measurement point, further measurements are taken, and a line of equal thickness marks the change in thickness.

1. Before calibration, check whether the numbers on the host display are clear to avoid shortages, hidden lights, etc.;

 

2. Keep the appearance of the standard block clean, without any appearance defects that affect the accuracy, such as rust;

 

3. The use of couplant, pay attention to the couplant should not be too small, it needs to cover the probe area;

 

4. During the calibration process, keep the probe tightly attached to the standard block and keep it still to ensure the accuracy of the data.

 

5. Because the sound velocity of different types of materials is different, it is recommended to measure the sound velocity of the same type of material according to the known material thickness first, confirm the sound velocity and then measure the material thickness, so that the measurement is more accurate;

 

6. Because of the principle of ultrasonic pulse reflection, the instrument cannot measure the thickness of insulating glass, because ultrasonic waves cannot penetrate the joint surface without coupling, so multi-layer materials such as insulating glass consisting of two layers of glass and air layers cannot be measured.

 

7. When measuring curved glass materials, it is necessary to pay attention to parallel or coaxial with the measurement material. In addition, it is also necessary to pay attention to the size of the material, and the probe of the instrument must be fully covered for accurate measurement;

 

8. When measuring irregular glass, there may be uneven thickness, which will affect the measurement of the instrument. We need to position and measure the material;
