Abstract
The utility model discloses a top-inserting hot-rod (tube) temperature measuring device which can be used to directly measure the operating temperature of the actuating medium. The structure of the utility model comprises a hot-rod (tube) casing and an enclosed space composed of an upper and bottom end cover in the hot-rod (tube) casing. The enclosed space is filled with actuating medium injected from material injecting tubes on the end covers. A temperature measuring protecting jacket assembly connected with the end covers of the hot-rod (tube) is provided with a protective cover and a protective sleeve which is inserted into the cavity of the hot-rod (tube). A temperature sensor is positioned in the protective sleeve, and the end part of the temperature sensor is inserted into the heat conducting medium in the protective sleeve. When the hot-rod (tube) is in use, the actuating medium realizes the transmission of the energy in the enclosed space of the hot-rod (tube), through continuous circulation of evaporation-condensation. In the circulation process, the temperature sensor can quickly and accurately reflect the operating temperature of the actuating medium.
