SU221823A1 - SHIELD MEASURING INSTRUMENT WITH LIGHT-CARRIER - Google Patents

Description

The invention relates to the field of instrumentation and is intended mainly to monitor the operation of complex objects (power plants, metallurgical and chemical units, etc.), which require a large number of parameters to be measured.

Known panel devices with a light pointer containing interchangeable scales, a measuring mechanism with movable mirrors, an illuminator, an optical system that forms light indicators, a matte screen, onto which light indicators are designed, prevent the use of a large number of interchangeable latches without increasing the size of the device.

The proposed device is equipped with a set of transparencies, on which images of scales are placed, located on the device for changing these transparencies. The device is illuminated by the illuminator and rotates by means of a mechanical transmission associated with a switch of measurement limits or measured parameters.

Transparencies are also printed on transparencies, projected on the screen along with interchangeable keyboards with a device consisting of a condenser and a lens.

improve the accuracy of monitored parameters.

FIG. 1 schematically shows the proposed device, the cut; in fig. 2 - the same, front view.

The device has a housing /, the front wall of which is a matte screen 2, several measuring mechanisms 3 (according to the number of channels located one under the other in one or several vertical rows). The movable parts of the measuring mechanisms are provided with mirrors 4. The lighting system consists of an incandescent lamp 5, a condenser 6, a diaphragm 7, auxiliary mirrors 5, and lenses 9.

Measuring mechanisms located below and above those shown in FIG. 1 are illuminated with a lamp 5 fitted with additional condensers, mirrors and lenses.

Light indicators 10 are projected from all measuring mechanisms onto a matte screen 2.

The scale images of all measuring mechanisms are plotted on transparencies 11 and projected onto screen 2 using incandescent lamp 12, condenser 13 and lens 14. Transparencies 11 are placed on a rotary disk 15. The latter has an axis 16 and is connected with a switch and a handle 17.

Simultaneously with the image on the screen can be designed a schematic image of the monitored objects 18. With the help of auxiliary lines 19 it can be shown at which points of the object measurements are taken. The scales can also project in the form of light strips the permissible limits of the monitored parameters.

When switching a multichannel device to the screen, a schematic representation of the object being monitored or its part and the scale of all channels is projected. At the same time, all measuring mechanisms are connected to the corresponding sensors, or sensors, or transducers installed on the object being monitored, and light indicators 10 show the values of all parameters.

When you switch a switch on the screen, the following object appears.

Slides can also be located on the generatrix of a swivel cylinder enclosing the lamp 12, rotated with a handle and a bevel gear. The knob simultaneously switches the switch of the measurement limits or the measured parameters.

Slides can also be applied on a flexible film that is rewound when the appliance switches.

Subject invention

1. A shield measuring device with a light pointer, containing interchangeable scales, a measuring mechanism with movable mirrors, an illuminator, an optical system that forms light indicators, a matte screen onto which light indicators are designed, characterized in that
