Abstract
Provided is an apparatus for measuring temperature inside a pipeline. According to the utility model, a threaded three-way pass is arranged at the end portion of a large-sized concrete pre-embedded water in-and-out pipe, with a water sealing heat insulation ring being inserted in the three-way pass, thereby ensuring the secure insertion of a built-in digital temperature sensor. A hollow screw and a temperature sensor are screwed in the three-way pass, thereby making the hollow screw be capable of generating adequate pressure upon the water sealing heat insulation ring to avoid leakage under hydraulic pressure. Moreover, the temperature sensor probe is just located at the center of the three-way water pipe. The temperature-measuring scope of the built-in temperature sensor ranges from -10 DEG C to 60 DEG C, with the error in the working scope within -0.3 to +0.3. The temperature measuring device is capable of removing the interference of the external temperature with the temperature measurement, accurately measuring the water temperature at the water in-and-out port, and accurately predicting internal heat exchange amount of the large volume concrete through the heat insulating processing with the pipe wall.
