Waterproof movable flange angle-ruler-shaped thermal resistor

Abstract

The invention discloses a waterproof movable flange angle-ruler-shaped thermal resistor. The waterproof movable flange angle-ruler-shaped thermal resistor comprises a thermal resistance element, a thermal resistance element connecting rod, a connecting flange, a clamping sleeve flange plate and a waterproof junction box, wherein the thermal resistance element is detachably connected with the thermal resistance element connecting rod through the connecting flange, the thermal resistance element is relatively perpendicular to the thermal resistance element connecting rod, the thermal resistanceelement is provided with the clamping sleeve flange plate, and the clamping sleeve flange plate is movably connected with the thermal resistance element. The waterproof movable flange angle-ruler-shaped thermal resistor has the advantages that the thermal resistance element is in right-angle connection with the thermal resistance element connecting rod through the connecting flange, so that the thermal resistance element and the waterproof junction box are arranged in a right angle, thereby providing convenience for performing temperature detection on some small space or special environments;the arrangement of the waterproof junction box can effectively prevent water, thereby protecting circuit components; the clamping sleeve flange plate can perform limiting protection on the thermal resistance element and facilitate the fixation of the thermal resistance element.

Description

【Technical field】 [0001] The invention relates to the technical field of thermal resistors, in particular to the technical field of square-shaped thermal resistors. 【Background technique】 [0002] Thermal resistance is the most commonly used temperature detector in the medium and low temperature area. Thermal resistance temperature measurement is based on the characteristic that the resistance value of metal conductors increases with the increase of temperature for temperature measurement. Its main features are high measurement accuracy and stable performance. Among them, the measurement accuracy of platinum thermal resistance is the highest. It is not only widely used in industrial temperature measurement, but also made into a standard reference instrument. Most thermal resistances are made of pure metal materials, and platinum and copper are the most widely used at present. In addition, materials such as nickel, manganese and rhodium have been used to manufacture thermal...
