Definitions
- the area of the invention is subject to the on-line measurement technology and on the other hand, the on-line acoustic device is reliably affected.
- This ECC contains, in addition to, an indus- trial coil and a cylindrical concentrate, made from an electromagnet and a mounted inlet Due to the creation of a single internal pole in the working zone, the known EPC achieves an increase in magnetic induction and, as a result, an increase in sensitivities.
- this famous EEC has a narrow contact area limited to 10 - 12 mm. For the best part, for the whole part of the process, a small number of processors are installed; 2 to a significant installation cost for the defect of the product.
- the magnetic system is made in the form of a core, a well-rested main body, in addition to a working, quick-moving magnets.
- the hearth is made in the form of a set of plates from electric steel and is separated for the purpose of simulating the electrical and acoustic function.
- the main part of the hearth is executed in the form of the party, the lesser understanding of the directive is directed to the working part.
- This ECC contains two induction coils, one for sounding, and another for industrial pulses (see ⁇ , ⁇ , 31305).
- Permanent magnets that circulate the core in the case of intermittent interference cause the increased magnitude of the magnetic field to increase their frequency of activity.
- magnets before being installed, the baits of the inductive system. It is possible for magnets to have a parallel angle or parallel ring shape. ⁇ In the latter case, magnets can supply their own electromagnets - solenoids.
- One of the options for the implementation of magnets can be made in the form of segments, sealed with bandages. It is advisable to reduce the loss of leakage on the surface of a magnetic system, to use a convenient and convenient way to fix the problem. In order to increase the sensitivity of the processor, it is desirable to perform a preferential concentration of the iron from the hardware, industrial hardware.

- These magnetic transmissions are for the purpose of transferring 8 inductances to the transducers in the form of electrical signals, which is understood as electrical signals (not shown in the figure).
- the proposed design of the magnetic system of the converter makes it possible to use 7 to receive the maximum induction in the case of the central magnet 5, as can be seen in Fig. 8, where the maximum concentration of the power lines is observed under the central magnet 5 in the operation.
- plate 9 from an external magnetic material has the effect of magnets 5.6 decreasing the loss of magnetism and eliminating the loss of signal.
- the electronic version of the EEP, shown in Figs. 4 - 7, is intended for use in conjunction with the ultrasound interface.
- the EEG can also be used for the manufacture of analogous equipment, but it is also used for the purpose of If you have to ensure that you have a 100% spare part supply, it is necessary to install an additional EPA, but there is a small amount of This version of the EPC has a small area of the box, replacing the 4-to 10-plus and more free space.
