Abstract

The invention relates to a control and measuring technique and allows to increase reliability by improving the safety of position-sensitive surfaces. The vessel 1 and the float 3 are made in the form of hollow spheres, with the shell of the float made light-tight with an equatorial transparent ring band. A light source 4 is placed in the center of the float; a part of the light flux of which in the form of a light strip creates on the part of the active surface of the photopotentiometer 2 limited by the light strip the excess conductivity giving information about the position of the light probe on the photo layer. The float is held in the desired position by a spherical crust 5, the inclination of the studied plane is judged by the indications of the measuring unit 6. 1 Il. with (L with with OO "00

SUBSTANCE: invention relates to co-operative technology, in particular, to devices for the inclination of objects,} tooling), air-conditioning machines in the mining industry, metal-cutting machines. etc.

The purpose of the invention is to ensure reliability (.- improve the safety of the position of the sensor surfaces, V: h.

BUT step. -,

On the sketch there is a schematic diagram of the proposed device.

In fact, from. - the material (light-shielding or not) of which the spherical vessel I is made, on its inner (or outer) side surface, photopotentiometers 2 are installed with a dielectric substrate length equal to the length of the semicircle with the radius of the sphere of the vessel 1. Light source 4 is located in the float 3. The float is held in a predetermined position by a spherical crust 5. For damping the oscillations, the latter is encased in a shell (for example, from rubber) HL) with a high decrement of mechanical oscillation damping. From two indications of the measuring unit 6, it is possible to judge the inclinations of the plane, since the output voltage of the photopotentiometers is a function of the position of the light probe on the photo layer,

The working part of the device is enclosed in a rectangular prism 7, all the bases of which are basic surfaces against which it is possible to measure the angles of inclination depending on the shape of the object.

The device works as follows.

Part of the light flux from the light source 4, the passage through the narrow transparent equatorial annular strip, on the light shell of the float 3 is transformed into a light probe, KOTopbrii in the form of the light strip falls on the active surface Composer B, Capaxai OB Editor And, Gorna Tehred L.

Topotentiometer 2 creates on its limited light strip a section of excess conductivity, which is a signal about the position of the light 5 probe on the photolayer or the angle of inclination of the base surface in the corresponding direction, the photopotentiometer length is 180 mm, and the position of the light probe is fixed to 1 mm, corresponds to the inclination of the base plane in the corresponding direction by 1 °.

 5 The range of measurement of the proposed device is practically unlimited - with its help one can directly determine the slopes in two mutually perpendicular directions of any

20 of the studied plane, arbitrarily oriented in space.
