The invention relates to measuring equipment and can be used for wireless remote measurement of temperature and frequency of pivotal objects under conditions of effect of strong electromagnetic fields, in remote systems and at measurement of temperature of objects at high electric potential. Device for measurement of temperature and frequency of rotary objects consists of 1- source of monochromatic radiation, 2 – first focusing lens, 3 – diaphragm, 4 – semi-transparent mirror, 5 – thermo-sensitive double-refracting crystal, 6 – mirror layer sputtered at side of thermo-sensitive double refracting crystal 5, 7 – second focusing lens, 8 – light divider, 9 – phase plate, 10 – first analyzer, 11 – second analyzer, 12 – first light filter, 13 – second light filter, 14 – first photo-receiver, 15 – second photo-receiver, 16 – first operation amplifier, 17 – second operation amplifier, 18 – first smoothing filter, 19 – second smoothing filter, 20 – first former of rectangular pulses, 21 – second former of rectangular pulses, 22 – first inverter, 23 – R-S trigger, 24 – first differentiation unit, 25 – second differentiation unit , 26 – ADT, 27 – first key circuit, 28 – second key circuit, 29 – first memory block, 30 – installation block, 31 – reversing counter, 32 – first adder, 33 – second memory block, 34 – second adder, 35 – transformer “code-code”, 366 – indication block, 37 – comparator, 38 – second inverter, 39 – multiplexer, 40 – frequency measuring device, 41 – rotary shaft. Device makes it possible to perform measurements of temperature and frequency of pivotable objects together and to increase accuracy of measurement. In the device there are removed “dead zones” at temperature scale, this makes it possible to measure temperature for cases of its quick and cyclic change and to provide remote measurements with minimal heat takeoff and at presence of electric potential with digital count. |
