Description

The existing devices for photoelectric measurements of small and displaced with a reamer, which consists of transparent and opaque nolos, make it possible to determine only one thing: firstly, the direction of one direction relative to another. To read and transmit to the Russian Federation) To do the measurement required by naiipHMep for automatic control of the technological process, the known devices do not have a network.

The proposed photoelectric trace, its ycTpoiicTBo does not have any of these drawbacks, and allows us to significantly extend the practical use of photoelectric optics to measure the displacement | 1 in automation and; and various processes. This is achieved by the fact that the image of the lattice is set, its element in this device is nullified by an optical system with an output of more than one unit on the grid of the actuating element, performed at the proper scale.

The drawing shows schematically the described device. With dipstick /

consisting of

Rendering is connected

black and transparent strips perpendicular to the direction of movement of this rod. Lens 3 is focused on the lattice 2. Lens 4 projects the image of the lattice 2, with a magnification larger than 1; half step. IN THE INITIAL Nozhozhenni. the grid 2 is projected onto the grid 5 in such a way that its strips are located from the shift of the n to the / i step, both with respect to the left and to the right of the right half of the penieTKH. If the grids are illuminated modulated

light from a lighting system consisting of a lamp 6 and a condenser 7 so that alternately left and right half the grids, then the photoelectric: signal, from the left and right halves to the futhocell 8 will be the same.

The change of lattice 2 relative to the lattice J in one direction or the other will cause an increase in the signal from one of the two floors and a decrease in it from the other. Amplifier 9

It amplifies this signal and supplies it to an electric motor 10, which moves the second grid until the luminosity of its two halves becomes the same.

On the corresponding, their axes of the gearbox, which sets in motion the carriage 11 with the grid 5, the arrows 12 are installed for a rough and accurate reading of the measured value. In parallel with this mechanism, the system of remote transmission of the measured value using selsyns can work.

Thus, the cumulative use of gratings and the increase in their scale provides not only the ability to read the measured value by an arrow pointer, but also allows the device to be used as a tracking system.

and apply a remote transmission using selsyns.
