From:Linshang Time:2022/11/30 17:01:10 Browse:372

Linshang ultrasonic thickness gauge adopts the latest high-performance and low-power consumption microprocessor technology, based on ultrasonic measurement principle which can measure the thickness of metal, plastic, glass and other materials. It can measure the thickness of all kinds of pipes and pressure vessels in production equipment, monitor thinning degree after corrosion in use, and also can accurately measure various plates and processed parts. There are LS211/LS212/LS213 at present. The following will introduce the price, product parameters and characteristics of the above several ultrasonic thickness gauges.

Frequently Asked Questions

  1. Does the instrument need to be calibrated before each use?

    It is not necessary, the instrument is already calibrated at the factory, so there is no need for frequent calibration.

  2. What kind of materials can your instruments test?

    Ultrasonic thickness gauge adopting pulse reflection ultrasonic measurement principle, all can make the ultrasonic wave at a constant speed in its internal propagation of various materials can be measured using this principle. The measured material is various, suitable for testing the thickness of various metals, plastics, ceramics, glass, glass fiber.

  3. What is the reason for the inaccuracy of the instrument test?

    1. The sound velocity is incorrect, if you can set the correct sound velocity by selecting the correct material, manually inputting sound velocity, and inverse measurement of the sound velocity through the material.

    2. There are dust, dirt, paint and other coverings on the surface of the measured object.

    3. The surface of the object to be measured is too rough or uneven, which will also affect the measurement accuracy.

    4. The ambient temperature during the test exceeds the working temperature range of the instrument.

  4. What is the max thickness of the material that the instrument can test?

    The max range of LS211 can reach 600mm, and the max range of LS212 and LS213 is 350mm.

  5. Is there any difference between LS212 and LS213?

    The resolution of LS212 can reach 0.001mm, and the resolution of LS213 is 0.01mm.

  6. What should I do when the coupling agent is used up?

    The couplant is a universal product and can be purchased online.

  7. Are you a manufacturer or trade company?

    We are factory , we have engineers for researching & designing  and workers for produce and operate etc, we could support you one-stop products and service.
