Thickness gauge ultrasonic А1208: description, characteristics, operating modes, purpose, testimonials

The ultrasonic thickness gauge А1208 is a universal device used for measuring the thickness of parts manufactured from various materials. A prerequisite for this is the ability of the material to absorb ultrasound.

In combination with an ultrasonic thickness gauge, a combined sensor is provided, which allows measuring parts from 800 μm to 300 mm thick. The device is made of high-quality materials of increased durability. The operation of the equipment together with a separate-combined sensor makes it possible to find corrosion centers of ulcer type. The device can be used in a wide temperature range from -30 to +50 degrees.

Purpose of thickness gauge А1208

The device supports work with combined and separately-combined converters. It is designed to measure the thickness of the walls of metal, cast iron, steel, plastic and other products with high attenuation of ultrasonic waves. Can be operated in difficult climatic conditions over a wide temperature range.

Using an ultrasonic thickness gauge А1208 with a combined converter equipped with a wear-resistant protector allows:

• Measure the thickness of thick-walled products made of plastic, cast iron, metal and other materials that have a high level of attenuation of ultrasound.
• Determine the thickness of metal products with applied paint and varnish. The device determines the thickness of the object without taking into account the coating layer with an object thickness of up to 15 mm and a coating thickness of 11 mm.
• Scan the monitored objects.

The search for corrosion sites for thin-walled small diameter pipes and measurement of their wall thickness is possible using a separately-combined converter.

Distinctive parameters of the device

• Significant expansion of the functionality of the device due to the use of two different types of converters.
• The power source is a lithium-ion battery. It is charged using a standard USB interface or the supplied network adapter.
• The automatic system for adjusting the surface quality of the measured materials was first used in the ultrasonic thickness gages A1208. It has no analogues and allows obtaining the most accurate results when measuring small-sized articles or having traces of corrosion. In this case, additional manual adjustment is not required.
• The display with a large diagonal on the TFT-matrix displays a high-quality image.
• The tool can be calibrated at the workplace and does not cause any problems.

Equipment options

Using two kinds of sensors allows you to expand the optional features of the device. Processing and subsequent storage of measurement results can be performed by connecting a thickness gauge to a personal computer via a USB interface.

In the description of the ultrasonic thickness gauge А1208 it is indicated that the device is resistant to low, high temperatures and sharp jumps. Equipped with a TFT-display of high definition and Li-Ion battery. Up to 50,000 measurement results can be stored in the device memory at the same time. High-precision instrument is designed for determining the thickness of the walls of plastic, metal products with a high level of attenuation of ultrasonic waves. The range of the measured thickness is from 0.8 to 300 mm.

Synchronize the ultrasonic thickness gauge can be simultaneously with separately-combined and direct combined converters. Connection of additional sensors widens the functionality of the device and allows you to determine the thickness of products made of metal, covered with paint or plastic layer.

• The thickness gauge body is made of high-quality impact-resistant plastic.
• The operator can obtain results with the utmost accuracy due to the variable discreteness.

Operating modes of the thickness gauge

The manufacturer provides several modes of operation of the A1208 thickness gauge. This means that each owner can choose the appropriate mode for himself. To determine what they differ, it is necessary to give a characterization to each regime.

Strobe mode

It is used to limit the controlled area. It is included in situations where, for example, it is required to determine the deviation of the thickness of the metal from the tolerance in the control of sheet metal. Auxiliary options: vibration, sound notification. They simplify and facilitate the work with the device. If the measurement results deviate from the tolerance, an alert tone sounds. The thickness gauge scale is displayed visually on the instrument display. The vibration and sound indication can be activated in the menu.

Memory mode

Mode of operation, designed to quickly determine the thickness of the material with subsequent insertion of results into the non-volatile memory of the device. In memory, you can store up to 50,000 results of measurements simultaneously. Memory mode allows you to group the results, which is very convenient when the operator is working on various objects. Online viewing and saving of results is organized clearly, logically and visually: the number of the cell to which the results will be entered is displayed on the thickness gauge display, and the previous measurements are also stored there. The records made earlier can be changed and overwritten if necessary.

Mode "Normal"

It allows not only to determine the thickness of the product, but also to evaluate the ratio of the result to a certain interval and the criterion for triggering an automatic defect alarm.

• The application of the upper limit of the thickness in the form of 100% and the lower limit in the form of a reject rate allows all measurements to be carried out with a simultaneous indication of the thickness of the object under study as a percentage of the value set in the settings.
• Variations in the results from the limits of acceptable values are accompanied by vibration, color and sound indication.
• The scale of the thickness gauge is clearly shown on the display of the device.

"Tolerance" mode

Used to quickly measure the thickness of products and determine the deviation of the results obtained from the specified nominal values. This mode is most often used in cases when permissible deviations are given in regulatory documents.

• Results of measurements are displayed on the device screen in the form of a difference between the real and nominal thickness of the object under study.
• If the results are rejected from the set parameters, the range of operation of the ASD can be adjusted.
• When the measurement results deviate from the permissible values, the operator is notified by means of vibration, sound and color indications.
• Graphical scale of measurements.
