Изобретение относитс  к области метрологического обеспечени  измерений температуры и предназначено дл  определени  динамических характеристик термометров погружени , например, при изготовлении и аттестапии термометров.The invention relates to the field of metrological assurance of temperature measurements and is intended to determine the dynamic characteristics of immersion thermometers, for example, in the manufacture and certification of thermometers.

Известны устройства дл  определени  динамических характеристик термометров, содержащие пружинный механизм перемещени  и рабочие камеры определенной температуры. Однако они не обеспечивают достаточной точности вследствие сложности регулировки скорости и перемещени  термометра, а также отсутстви  теплоизол ции рабочих камер друг от друга.Devices are known for determining the dynamic characteristics of thermometers, comprising a spring-loaded mechanism for moving and working chambers of a certain temperature. However, they do not provide sufficient accuracy due to the difficulty of adjusting the speed and movement of the thermometer, as well as the lack of thermal insulation of the working chambers from each other.

Цель изобретени  - повышение точности определени  динамических характеристик термометров погружени . Это достиг аетс  введением в устройство теплового экрана шторного типа, размещенного между рабочими камерами, а также выполнением механизма перемещени  термометров в виде подпружиненной каретки, перемещающейс  по направл ющим и фиксируемой в конечных положени х стопорамиThe purpose of the invention is to improve the accuracy of determining the dynamic characteristics of immersion thermometers. This is achieved by introducing into the device a heat shield of a curtain type placed between the working chambers, as well as the implementation of the mechanism for moving thermometers in the form of a spring-loaded carriage moving along guides and fixed in end positions by stoppers

На чертеже изображено предложенное устройство .The drawing shows the proposed device.

На основании 1 смонтированы термокамеры начальной температуры 2 и механизм перемещени  термометров, выполненный в виде каретки 3, перемещающейс  под воздействием пружины 4 по направл ющим 5 и фиксируемой стопором 6, установленным на верхней подвижной платформе 7. В основании 1 соосно с термокамерой начальной температуры размещена термокамера конечной температуры 8. Друг от друга термокамеры отделены теплоизолирующим экраном 9 с затвором щторного типа 10, закрепленным на нижней подвижной платформе 11. Верхн   подвижна  платформа вращением маховика 12 перемещаетс  по стойкам 13 до положени , соответствующего необходимому напр жению пружины 4. Нижн   подвижна  платформа 11 перемещаетс  до положени , при котором термометр 14 будет находитьс  в зоне рабочей камеры 2. Температура рабочей среды в термокамерах контролируетс  с помощью образцовых термометров. Врем  перемещени  исследуемого термометра изThermal chambers of initial temperature 2 are mounted on base 1, and a mechanism for moving thermometers, made in the form of a carriage 3, moves under the influence of a spring 4 along guide rails 5 and fixed by a stopper 6 installed on the upper movable platform 7. At the base 1, a heat chamber is placed coaxially with the initial temperature chamber. of the final temperature 8. From each other, the heat chambers are separated by a heat insulating screen 9 with a shutter of a 10-shutter type 10 mounted on the lower movable platform 11. The upper movable platform is rotation The flywheel 12 moves along the uprights 13 to a position corresponding to the required voltage of the spring 4. The lower movable platform 11 moves to a position at which the thermometer 14 will be located in the zone of the working chamber 2. The temperature of the working medium in the heat chambers is monitored using reference thermometers. The time of movement of the thermometer under study from
