Abstract

Изобретение относится к измерительной технике и может быть использовано при измерении температуры газообразных, жидких и твердых сред. Предложен датчик температуры, включающий в себя чувствительный элемент, выполненный в виде кабельного термоэлектрического преобразователя, и защитный чехол, состоящий из отрезка трубы и пробки. Отличительной особенностью предлагаемого датчика является то, что пробка имеет длину, равную или превышающую свой диаметр, и глухое отверстие, предназначенное для размещения части чувствительного элемента со стороны рабочего спая, при этом торец пробки выступает за трубу на величину выступа K, находящуюся в диапазоне 0,5А≤K≤2,0А, где А - диаметр чувствительного элемента. Технический результат - снижение тепловой инерции при сохранении блочно-модульного типа исполнения, что позволяет сохранить все достоинства, присущие ему.The invention relates to measuring equipment and can be used when measuring the temperature of gaseous, liquid and solid media. The proposed temperature sensor, which includes a sensitive element, made in the form of a cable thermoelectric converter, and a protective cover, consisting of a section of pipe and tube. A distinctive feature of the proposed sensor is that the cork has a length equal to or greater than its diameter, and a blind hole designed to accommodate part of the sensing element on the side of the working junction, while the end of the cork protrudes beyond the pipe by an amount of protrusion K in the range 0, 5А≤K≤2,0А, where A is the diameter of the sensitive element. The technical result is the reduction of thermal inertia while maintaining the block-modular type of execution, which allows you to save all the advantages inherent in it.
