Description

Technical Field

[0001] The utility model belongs to the technical field of reed switch liquid level sensors, and particularly relates to a temperature transmitter with a bracket. Background Art

[0002] As an important industrial automation instrument, temperature transmitters play a crucial role in a wide range of industrial fields. They are mainly used to measure and convert temperature signals and convert them into standardized output signals, such as 4 - 20mA current signals or 0 - 5V / 0 - 10V voltage signals, which can be easily read and processed by remote control systems. The application scenarios of temperature transmitters are very extensive, covering multiple fields from mechanical devices, laboratories to wind power facilities, production workshops, etc. For example, in wind power generation, temperature transmitters are used to monitor the operating temperature of generators to prevent equipment failures caused by overheating; in laboratories, they are used to precisely control the temperature inside reaction vessels to ensure that chemical reactions proceed under optimal conditions; while in the food processing industry, they are used to monitor the temperature of ovens or refrigerators to ensure product quality. However, traditional temperature transmitters often face the problem of poor installation positions, which may lead to measurement errors. In addition, the protective sleeves of transmitters often use carbon steel materials, which are prone to oxidation and rust in water and air environments, resulting in the fracture of the sleeves. More seriously, due to the ineffective fixation of the sleeves and the slender structure of the probes, the probes are prone to bending deformation during use, and even the internal leads may have a ground short circuit, which greatly affects the accuracy and reliability of temperature measurement. To overcome the above problems, existing technical solutions usually adopt relatively simple structural designs, such as improving the sleeve material to enhance corrosion resistance or using simple fixation methods to reduce the shaking of the probes. However, these solutions often fail to fundamentally solve the problems, especially in certain specific harsh environments, such as water treatment facilities, where the transmitter needs to work in deep water, and traditional methods are difficult to effectively handle.

By optimizing the material, structural design and installation method of the protective sleeve, the present invention aims to provide a more reliable and durable temperature transmitter solution.

[0004] To solve the above problems, the technical solution adopted by the present utility model is as follows: a temperature transmitter with a bracket, including a temperature transmitter body, a thermal resistor, a protection tube and a bracket.

The upper flange and the lower flange are movably connected. The bracket is sleeved outside the thermal resistor and can be fixed to the wall of the regulating tank.

[0005] Compared with the prior art, the beneficial effects of the present utility model are as follows: The daily platinum resistor is removed, the three-wire cable is butt-connected with the thermal resistor, and an extended protection tube is added outside the extension part, which improves the overall stiffness of the extension part, reduces the bending deformation of the probe due to its slender structure, and solves the problem of poor installation position of the original transmitter by designing a special installation bracket and a support platform, improving the installation stability of the transmitter. The bracket mounting seat is on the edge aisle of the regulating tank wall, avoiding the risk of personnel entering the bottom of the tank for installation. At the same time, it can effectively reduce the impact of the waves generated during the stirring of the regulating tank on the protection tube and its thermal resistor. More importantly, by locking the protection sleeve with the flange, the positioning accuracy of the thermal resistor is ensured, further improving the measurement stability. The protection sleeve is made of stainless steel material, which significantly enhances the anti-corrosion ability compared with the original carbon steel material and reduces the risk of sleeve fracture caused by oxidation and rust.
