The ultrasonic thickness gauge ADL UT 35 is designed for measuring the thickness of products and structures made of metal alloys and isotropic non-metallic materials with one-sided access to them.

The ADL UT 35 thickness gauge is often used for rapid measurement of the thickness of products made of various materials subject to corrosion, erosion, internal deposits, including those with a coarse-grained structure, metal and non-metal products: sheets, containers, pipes, pipelines, bridges, housings, transport and others structures during their operation to determine the corrosion state or after their manufacture.

The advantages of the thickness gauge are presentation of the signal in the form of an A-scan, control of thickness through the coating, construction of a thickness profile of the controlled surface (B-scan), measurement of ultra-small thicknesses, wide functional amplification of the useful signal, simple device setup, bright and colorful display, various thickness measurement modes , a wide library of sensors, the ability to work with any converters.

It doesn’t matter if it is flat or curved, you will get the exact thickness. With the UT 35 thickness gauge, you can use any ultrasonic transducers with frequencies from 0.5 to 15 MHz, both combined (including with delay lines) and separate-combined (separate) types.

The thickness gauge provides various thickness control capabilities – high-precision measurement of zero crossing time, measurement of time between echo-echo signals, measurement of metal thickness under coatings, etc.

The presence of a real signal on the screen eliminates typical errors in thickness measurements using ultrasonic testing and increases the accuracy of measurements.

Features of the UT 35 thickness gauge:

  • Measurement range from 0.4 to 600 mm;
  • Auto-detection of connected converters with built-in memory;
  • Connecting high-temperature converters up to 350 °C;
  • Measurement methods:
    Pulse – Echo – classic method
    Echo-Echo-Echo measurements – measurement of metal thickness through the coating;
  • Graphical display and saving of scans A and B;
  • Connecting a wide range of converters (both combined and separate-combined);
  • Ability to set thickness tolerances (upper and lower values)
  • High speed of measurements and processing due to a powerful microcontroller and additional RAM;
  • Ability to calibrate both the speed of ultrasound in the material and the thickness of the material.
  • Reliable shockproof, dust- and moisture-proof housing;
  • Stores a large number of measurement results, including scans A and B;
  • Specialized software;
  • High-contrast color display with adjustable brightness;
  • Data transfer to PC via standard USB-C connectors;
  • Possibility of measuring thickness through the coating without cleaning the surface
  • The presence of a B-scan, which allows you to build an accurate and visually understandable profile of the bottom of the product with recording of the minimum signal for the entire scanning time. This feature allows you to quickly scan large areas.
  • The presence of a signal in the form of an A-scan, which eliminates measurement error, because The operator understands from the mark on the scan in which zone the measurement was made, in contrast to the traditional digital one (the typical error is doubling the thickness), resulting in increased measurement accuracy.
  • In the setup mode, the full range of options is available for adjusting the gain of the receiving path, AGC, TCG, generator and receiver parameters, calibrating the prismatic delay and material rotation speed, and so on.
  • Highly accurate zero-crossing measurement, two independent gates and a state-of-the-art low-noise receiver enable precision measurements of ultra-thin thicknesses with combined transducers in echo-echo-echo mode, including under a variety of coatings.
  • “DIGIT”mode allows you to remove unnecessary information from the screen for typical traditional applications, turning a good technical device into an easy-to-use management tool.
  • In the TABLE mode, the user can create a tabular matrix for monitoring large-sized standard products by marking control points. This set of results can be transferred to a PC for subsequent statistical analysis.
  • Thanks to the sensor library, setting up the device is quick and easy.
    High reliability and safety, which is very convenient when working in workshops.
  • Convenient mount on the operator’s hand, which greatly facilitates work in hard-to-reach places or at heights when the operator needs his hands free.
