Изобретение относитс к области измерительной техники.The invention relates to the field of measurement technology.
Известны терморезисторы с косвенным подогревом (ТКП), в которых нагреватель выполнен в виде проволочной спирали, навитой на поверхность терморезистора. У терморезисторов типа ТКП рабочий элемент заключен в цилиндрический подогреватель. Необходимость применени плоских терморезисторов с косвенным подогревом потребовала создани специальных плоских нагревателей, что сопр жено с дополнительными затратами на разработки таких нагревателей.Known thermistors with indirect heating (TCH), in which the heater is made in the form of a wire helix wound on the surface of the thermistor. In thermistors of type TKP, the working element is enclosed in a cylindrical heater. The need to use flat thermistors with indirect heating required the creation of special flat heaters, which is associated with additional costs for the development of such heaters.
Предлагаетс в качестве нагревател дл плоского терморезистора с косвенным подогревом примен ть тензометр фольгового типа.It is proposed to use a foil-type strain gauge as a heater for a flat thermistor with indirect heating.
На чертеже показаны плоские терморезисторы с косвенным подогревом, состо щие из терморезистора J фольгового тензометра 2, приклеенного к поверхности плоского терморезистора , и теплоизол ционного сло 3.The drawing shows flat thermistors with indirect heating, consisting of a thermistor J of a foil strain gauge 2 glued to the surface of a flat thermistor, and a heat insulating layer 3.
Терморезистор работает следующим образом .Thermistor operates as follows.
К тензометру 2 подключают источник стабилизированного электропитани Un- При этом в тензометре выдел етс определенное количество теплаTo the strain gauge 2 a source of stabilized power supply Un- is connected. A certain amount of heat is generated in the strain gauge
д 0,,d 0 ,,
где / - ток через тензометр,where / is the current through the strain gauge,
R - сопротивление тензометра.R is the resistance of the strain gauge.
Благодар теплоизол ционному слою 3 поток тепла направл етс в окружающую среду через терморезистор.Due to the heat insulating layer 3, the heat flux is directed to the environment through a thermistor.
Предмет изобретени Subject invention
Применение тензометра фольгового типа в качестве нагревател дл плоского терморезистора с косвенным подогревом.The use of foil-type strain gauge as a heater for a flat thermistor with indirect heating.
