Description
закрепленной на опорной колодке 3, Над поверхностью опорной колодки 3. выступают четыре штырька 5, ограничивающие деформацию термопары при прижатии еа к поверхности.fixed on the support block 3, Four pins 5 protrude above the surface of the support block 3. They limit the deformation of the thermocouple when it is pressed against the surface.
Така конструкци чувствительного элемента обэспечивает надежнъ1й контакт термопары 1 с контролируемой поверхностью б (фиг. 4) и посто нство усили ее прижати при касании штырьков 5 поверхности 6.Дл уменьшэни теплового контакта с термопарой 1 и уменьшени отвода тепла через пружину 4 наружна поверхность середины дуги пружины 4 может быть защищена термоизол ционным покрытием , материал которого зависит от диапазона измерени температуры поверхности .Such a design of the sensing element ensures reliable contact of thermocouple 1 with a controlled surface b (Fig. 4) and the constant force of pressing it when the pins 5 touch the surface 6. To reduce thermal contact with thermocouple 1 and reduce heat removal through the spring 4, the outer surface of the center of the spring arc 4 may be protected by a thermal insulation coating, the material of which depends on the measuring range of the surface temperature.
Дл изготовлени пружины 4 можно использовать пружинную проволоку диаметром до 0,5 мм. или ленту, например, шириной до 2 мм, толщиной 0,10-0,15мм из материала с малой теплопроводностью .For the manufacture of spring 4, spring wires with a diameter of up to 0.5 mm can be used. or tape, for example, up to 2 mm wide, 0.10-0.15 mm thick, from a material with low thermal conductivity.
Мала масса термопары 1 и пружины 4 обеспечивает хорошее быстродействие чувствительного элемента, особенно при контроле температуры металлических поверхностей.The low mass of thermocouple 1 and spring 4 provides a good speed of the sensitive element, especially when controlling the temperature of metal surfaces.
