DEVICE FOR CONTACT-LESS MEASUREMENT OF TEMPERATURE

Device for contact-less measurement of temperature has objective, diaphragm opening of which is sector with apex at optical axis, mirror arranged as a cone, straight generatrixes of side conical surface of this one form angle at its apex smaller than 90°,and straight generatrixes of central conical surface form angle at apex 90°, and infra-red receiver that is set of infra-red sensors placed on main optical axis one after another, receiving platforms of those are normal to main optical axis. At that outputs or n infrared sensors are connected to inlet buses of buffer register and transformer frequency-voltage, output bus of reversing counter is connected to input bus of digital-analog transformer output of which is connected to input of second transformer voltage-frequency. Shaft of stepping motor is connected to diaphragm, output of source of reference voltage is connected to input of first transformer voltage-frequency output of which is connected to second inputs of video-control block and second analog-digital transformer, with first input of first switch and to inputs of interface block of voltage generator that changes in stepped way, and frequency divider output of which is connected top the first inputs of first element AND, and buffer register. Output of the first element AND is connected to the first input of counter second input of which together with the first input of the second element AND are connected to output of element NOT. Output of the second element AND is connected to third input of reversing counter, output of element AND is connected to the fifth input of video-control block and to other inputs of first switch and buffer register output bus of which is connected to u=input bus of the first switch output of which is connected to first inputs of video-control block and second analog-digital transformer output bus of which is connected to input bus of interface block output bus of which is connected to circuits of computer. Output bus of counter is connected to the first input bus of permanent memory block first and second outputs of which are connected to the second inputs of the first and second control amplifiers, respectively, first inputs of those are connected to the output of power generator that changes in stepped way, and outputs are connected to the third and fourth inputs of video-control block, respectively. Output of transformer frequency-voltage is connected to the first input of comparator second input of which is conne
