Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers differential magnetic field sensors for rolled round steel bar quality control under a manufacturing agreement and is looking for partners interested in distribution services agreement.

OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus designed and manufactures differential magnetic field sensors. The sensor is a probe with a magnetic core and is used to detect cracks on the surface of rolled round bar.

The differential probe (DP) consists of two coils with a magnetic core located at 0,6 mm distance from each other, mounted in the housing.

The probe allows detecting cracks with a width over 0,1 mm and a length over 11,5 mm at a speed of movement of the probe relative to the surface up to 6 m/s.

The Institute has developed and manufactured:
* a specialized stand forming a homogeneous alternating magnetic field with a frequency of 10 kHz;
* a stand simulating defects of a rolled round bars to tune the sensor according to the signal-to-noise ratio and sensor functionality check.

Areas of application:
* manufacturers of induction control equipment;
* metallurgy (manufacture of rolled round steel bars).

Minsk Research Institute of Radiomaterials offers partners:
* differential magnetic field sensors under a manufacturing agreement;
* differential magnetic field sensors under a distribution services agreement.

Differential magnetic field sensors are innovative products and have no analogues in the Republic of Belarus and CIS countries.

Import substitution of a component product of Fluke Corporation (USA). The cost of a differential magnetic field sensors by MNIIRM is 25% cheaper.

The differential magnetic field sensor was tested on the NOVAFLUX REL 200 system at JSC "BMZ".

The specialization of the institute includes the following main areas:
* development and production of the element base and functional units of microwave technology (solid-state microwave monolithic integrated circuits - low-noise amplifiers and power amplifiers, protective devices, switches, attenuators, frequency converters; microwave modules, etc.);
* development and production of optoelectronic components and modules based on them (photodetectors, light emitting diodes, semiconductor lasers, receiving and transmitting optical modules);
* production of materials for semiconductor production - gallium arsenide substrates of the "epi-ready" standard;
* development of sensor technology, modules and systems (sensors for inclination, pressure, acceleration, electronic compass, etc.);
* development and production of medical equipment.

The research and production base of the institute includes dedicated equipment which allows to develop and perform a full cycle of technological operations for the manufacture of microwaves, optoelectronic components, sensors of physical quantities based on microelectromechanical systems, equipment for the manufacture of medical products - Glucosen sensors etc. In particular, the equipment allows cutting semiconductor ingots of A3B5 compounds (GaAs, InP, GaN, etc.), grinding and polishing wafers, epitaxial growth, thermal diffusion and implantation of dopants, microcircuit packaging, control of their parameters, etc.

The Institute has a licensed software for electrodynamic calculations, its own library of standard elements, methods for monitoring and testing microwave components in the C, S, L, X, K wavelength ranges, electronic lithography equipment with a resolution of 100 nm, which provides a modern level of design standards.

As part of the specialization, the development of technologies, components and devices for various radio-electronic systems is carried out: radar systems, fiber-optic communication lines, laser rangefinders, systems for leveling and orientation of objects, control systems, guidance and navigation, etc.
