Problems solved by technology
Since metal is a good conductor of heat, it is easy to bring the heat of the measured material to the environment or the heat of the environment to the probe, especially when the temperature difference between the measured material and the surrounding environment is large, resulting in inaccurate temperature measurement; The probe rod is easily corroded in an environment with high oxidizing and reducing properties, and its service life is short; in addition, ceramic materials are also used, but they are often not strong enough to be suitable for measuring high-hardness materials, especially the probe rod needs to be plugged and pulled out frequently It is easy to be broken; currently only one temperature sensor can be placed on the commonly used probe rod, and multiple probe rods need to be inserted to measure the temperature of different layers of inhomogeneous media, which is very inconvenient to operate; because there is no scale mark on the probe rod, It is not easy to grasp the depth of probe rod insertion

Embodiment
[0011] First of all, please combine Figure 1 and Figure 2, a probe rod 1 is a hollow metal tube with anti-rust paint inside, and a temperature sensor 2 is installed in the tube. ) to install the farthest sensor. The specific operation steps are: put the inner waterproof plastic tube (not shown in the figure) on the signal line 4 of the temperature sensor 2 respectively, and then insert the temperature sensor 2 into the metal tube from the head of the probe rod 1 , after aligning with the lowermost scale line, seal the temperature sensor 2 with a sealing material for waterproofing. The sealing material can be a commercially available sealant. Repeat the above steps to install multiple temperature sensors as required. The rod body of the probe rod 1 is coated with an organic polymer material layer 5 . In this embodiment, polytetrafluoroethylene is coated on the probe rod 1 , and the process of coating polytetrafluoroethylene is a known technology, which will not be described in ...

A composite temp probe is composed of a hollow metal tube coated by organic high-molecular layer, at least one temp sensor, and a socket on the top of metal tube. It can measure the temps at more points in solid or liquid medium at same time. Its advantages are high correctness, and high resistance to corrosion, ageing, acid, and alkali.
Description
technical field [0001] The invention belongs to a temperature probe, in particular to a composite temperature probe. Background technique [0002] People widely use various temperature probes to detect the temperature of various media in various fields, which has become very common in itself. Traditional temperature probes, especially those used in automatic temperature monitoring of corrosive environments such as compost, fermentation, soil, ocean, waste water, and inhomogeneous media, basically use metal materials for their probe rods. Since metal is a good conductor of heat, it is easy to bring the heat of the measured material to the environment or the heat of the environment to the probe, especially when the temperature difference between the measured material and the surrounding environment is large, resulting in inaccurate temperature measurement; The probe rod is easily corroded in an environment with high oxidizing and reducing properties, and its service life is s...
