Description
Изобретение относитс к температурным измерени м и может быть использовано дл бесконтактного измерени температуры поверхности вращающихс объектов.The invention relates to temperature measurements and can be used for non-contact measurement of the surface temperature of rotating objects.
Цель изобретени - повышение надежности устройства.The purpose of the invention is to increase the reliability of the device.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит нанесенные на объект 1 термоиндикаторные покрыти 2 с разной температурой перехода, которые мен ют при нагревании цвет с темного на светльй или наоборот. Через оптическую систему 3 покрыти св заны с источником 4 света и фотоприемником 5, подключенным к счетчику 6 импульсов.The device contains thermal indicator coatings 2 applied to object 1 with different transition temperatures, which change when heated from dark to light or vice versa. Through the optical system 3, the coatings are connected to a light source 4 and a photodetector 5 connected to a counter 6 pulses.
Устройство работает следующим образом .The device works as follows.
Излучение источника 4 фокусируетс с помощью оптической системы 3 на линии покрытий 2. По мере нагрева линии мен ют темный цвет на светльй илThe radiation from source 4 is focused by the optical system 3 on the coating line 2. As the line heats up, the dark color changes to light
наоборот. При этом освещенность фотоприемника 5 измен етс таким образом, что на его выходе по вл етс импульс. Число импульсов за один оборот равно числу светлых линий 2. Счетчик 6 импульсов осуществл ет подсчет числа импульсов, пришедших за один оборот объекта 1, которое однозначно св заfio с температурой.vice versa. In this case, the illumination of the photodetector 5 changes in such a way that a pulse appears at its output. The number of pulses per revolution is equal to the number of light lines 2. A pulse counter 6 counts the number of pulses that came in one revolution of object 1, which is uniquely related to temperature.
