Hardness tester TPTs-7DL









Linked profile in other language
Larisa Zezetko
Institute of Applied Physics offers customers a hardness tester TPTs-7 DL under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.
The TPTs-7 DL hardness tester (in Russian) is a modification of the TPTs-7 designed for non-destructive measurement of the hardness of products in hard-to-reach places using a special nozzle and an elongated indenter.
TPTs-7 DL has small overall dimensions and weight, as well as the ability to replace the indenter with a standard one used in TPTs-7.

Areas of use:
energy, construction, mechanical engineering, metallurgy.

The measurement of hardness with the TPTs-7 DL device is carried out using the dependence of the velocity recovery coefficient on the plastic properties of the material. A test micro-impact with a striker-indenter (standard, or elongated) is carried out on the surface of the controlled product. The motion parameters of the indenter are recorded by a sensor that generates a measuring signal. Based on the data obtained, the value of the hardness of the controlled material is determined. Since the standard and extended indenters of the TPTs-7 DL instrument form different signals, it is important that the user selects the correct presets when working with the instrument.

Advantages and Innovations
The device has the following advantages:

- Automatic correction of readings depending on the orientation of the device in space
- Control of the hardness of products with a wall thickness of 8 mm or more
- Measurement of hardness in hard-to-reach places (for example, on gear teeth)
- The possibility of using a hardness tester to control products without lapping to a massive base starting from a mass of 1.5 kg
- Automatic calculation and display of the arithmetic mean of the measurement results

At the request of the buyer, translation into any of the generally accepted scales (HB, HRC, HV, HRB, HS, Rm) can also be configured.

Hardness testers allow you to evaluate the hardness of other metal materials: alloy steels, cast irons, non-ferrous metals and alloys (on request).

Additional comments
The main scientific fields of the Institute:
- Physics of non-destructive testing;
- Development of methods and means of non-destructive testing and technical diagnostics of materials, products and technological processes;
- Creation of scientific foundations of information technologies for non-destructive testing and technical diagnostics.

Non-destructive testing methods developed at the institute:
- Methods of ultrasonic flaw detection, structuroscopy, thickness measurement of surface hardened layers;
- Capillary control method;
- Pulse magnetic control method;
- Methods of magnetic thickness measurement of coatings;
- Thermopower method;
- Eddy current methods of flaw detection and structuroscopy;
- Method of magnetic noise structuroscopy;
- Methods for monitoring the magnetic characteristics of soft magnetic materials, magnetic fields and residual magnetization;
- Methods of radio wave flaw detection, structuroscopy, thickness measurement;
- Contact-dynamic method for monitoring the physical and mechanical characteristics of materials;
- Methods of image reconstruction in x-ray tomography.

Solved applied tasks:
- Control of defects in the continuity of parts, blanks and structural elements (defectoscopy);
- Control of the structure and physical and mechanical characteristics of materials;
- Control of the geometric parameters of products, coatings and surface hardened layers;
- Control of the stress-strain state of metal structures;
- Technical diagnostics of objects.

Applied developments of the institute are characterized by a wide range of scientific and technical problems to be solved, which are of a diversified nature, and the developed modern methods and means of non-destructive testing and technical diagnostics are used in energy, space technology, metallurgy, auto, tractor and agricultural engineering, motor building, construction , welding industry, electronics, petrochemistry, railway and road transport, pipeline transport, bridge building, aircraft building, repair services, utilities, medicine, sports, forensics, etc.

The institute has two laboratories accredited by the State Standard of the Republic of Belarus: a testing laboratory for non-destructive testing and a verification laboratory.

Objects of control - Parts, blanks, castings, rolled products, forgings, welded joints, building and other structures made of metal, concrete, plastics, composite materials, pipelines, boilers, tanks, metal structures of hoisting and transport machines, products made of rubber materials, foundations, road coatings, machines and mechanisms, electrical machines, etc.

The Institute of Applied Physics is the only academic institute both in the Republic of Belarus and abroad that specializes in the field of physics of non-destructive testing and technical diagnostics. The results of research on the development of the scientific foundations of the theory of magnetism, electromagnetic, ultrasonic, radio wave, contact-dynamic, capillary and other methods of non-destructive testing brought fame to the institute. Scientists of the institute have created dozens of new types of methods and means of control, protected by copyright certificates and patents from the leading countries of the world, introduced at many industrial enterprises of the republic and abroad. The Institute maintains active international relations, being one of the founders of the World Federation of Non-Destructive Testing Centers (the headquarters of the World Federation is located in the USA). Representatives of the Institute traditionally head the Belarusian Association of Non-Destructive Testing and Technical Diagnostics, which is part of the European Federation of Non-Destructive Testing (EFNDT).
