Problems solved by technology
[0002] At present, the temperature measuring device used is generally composed of a temperature measuring core, a protective tube and a junction box. Many installation points of the temperature measuring device are in relatively remote places. When the protective tube starts to leak a small amount, it is often difficult to be found. Generally, a serious leak has formed when it is discovered, causing the junction box and temperature measuring core in the temperature measuring device to be corroded by the fluid medium, resulting in waste, and also seriously threatening the safety of production and operation.

Embodiment Construction
[0022] A leak detection temperature measuring device, mainly including a temperature measuring core 1, a protective tube 2 and a junction box 3, the temperature measuring core 1 is placed in one end of a sealed protective tube 2, and the other end of the protective tube 2 is fixedly connected to the junction box 3, one end; the junction box 3 is provided with a terminal 4, the temperature measuring core 1 is electrically connected to the terminal 4 in the junction box, and the temperature measuring device is also provided with a pressure measuring body 5, which can measure the protection The pressure in the pipe 2 is output as a signal. The pressure measuring body can detect the pressure inside the protection tube, because when in use, the outside of the protection tube is in the measured fluid medium, when the protection tube begins to leak slightly, the pressure inside the protection tube will change accordingly, the pressure measuring body After the signal is measured, a le...

The invention discloses a leak detection type temperature measurement device, which mainly comprises a temperature measurement core body, a protection tube, a connecting box and a pressure measurement body, wherein the temperature measurement core body is arranged in one end of the sealed protection tube, and the other end of the protection tube is fixedly connected to one end of the connecting box; a connecting terminal is arranged in the connecting box; the temperature measurement core body is electrically connected with the connecting terminal in the connecting box; and the pressure measurement body can measure pressure in the protection tube and output the pressure in the form of a signal. The temperature measurement device can measure temperature, detect whether the protection tube leaks and supply two-layer protection; a maintainer can be reminded of changing the temperature measurement device timely; and the temperature measurement core body is protected from being damaged, so that the cost is reduced.
Description
technical field [0001] The invention relates to a temperature measuring device, in particular to a leak detection type temperature measuring device. Background technique [0002] At present, the temperature measuring device used is generally composed of a temperature measuring core, a protective tube and a junction box. Many installation points of the temperature measuring device are in relatively remote places. When the protective tube starts to leak a small amount, it is often difficult to be found. Generally, a serious leak has formed when it is discovered, causing the junction box and temperature measuring core in the temperature measuring device to be corroded by the fluid medium, resulting in waste, and also seriously threatening the safety of production and operation. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a leak detection temperature measuring device, which can not only measure the temperature, but ...
