[0011] Figure 1 A structural schematic diagram (three-dimensional view) provided for this utility model. Detailed Implementation

[0012] To better understand the technical solution of this utility model, the embodiments provided by this utility model are described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, this embodiment provides a handheld platinum resistance temperature sensor, comprising: a housing 5, a platinum resistance temperature sensing chip 1, and a connecting wire 7. The connecting wire 7 passes through the housing 5 and is connected to the platinum resistance temperature sensing chip 1. It also includes a handheld handle 4 and an insulating tube 2, with holes at both ends of the insulating tube 2. One end of the insulating tube 2 has a placement position where the platinum resistance temperature sensing chip 1 is placed. The other end of the insulating tube 2 is disposed within the handheld handle 4, and a portion of the housing 5 is also disposed within the handheld handle 4. The connecting wire 7 passes through the housing 5 and the insulating tube 2 and is connected to the platinum resistance temperature sensing chip 1.

[0014] In this embodiment, the platinum resistance temperature sensor chip 1 is used to contact the object to be measured. After temperature measurement, the temperature data is transmitted through the connecting wire 7. The platinum resistance temperature sensor chip 1 uses a high-precision platinum resistance thermometer made according to a specific welding process. Platinum resistance thermometers have the advantages of high precision and good stability. In this application, the platinum resistance element undergoes special surface treatment to make it resistant to high temperatures and can operate normally in an environment of 200°C. One side of the platinum resistance ceramic has excellent thermal conductivity, playing a key role in the sensor. When the ambient temperature changes, the platinum resistance thermometer can respond quickly, converting the temperature change into a measurable electrical signal. Whether in a rapidly heating or cooling environment, it can promptly capture temperature fluctuations. This characteristic makes it perform exceptionally well in applications that are sensitive to temperature changes and require rapid response, such as in the heat dissipation monitoring system of electronic devices, where it can quickly detect sudden increases in chip temperature, thereby taking timely heat dissipation measures to prevent damage to the equipment due to overheating.

[0015] A key feature of this embodiment is the inclusion of a handheld handle 4 and an insulating tube 2. The handheld handle 4 is made of a high-temperature resistant and high-pressure resistant insulating material. This insulating material can withstand high voltage and does not exhibit reduced insulation performance at high temperatures. Furthermore, the handheld handle 4 facilitates operation and easy handling during temperature measurement. The insulating tube 2 is made of a high-strength injection-molded tube (such as PTFE, PA66+glass fiber), possessing properties such as high-temperature resistance, wear resistance, corrosion resistance, non-stickiness, and weather resistance. One end of the insulating tube 2 has a placement position for mounting the platinum resistance temperature sensor 1 horizontally, allowing for a larger contact area between the measured surface and the platinum resistance temperature sensor 1, thus improving the accuracy and response speed of the temperature sensor. To ensure a stable connection between the connecting wire 7 and the platinum resistance temperature sensor 1, the insulating tube 2 is open at both ends, with the connecting wire 7 passing through the middle of the insulating tube 2 and connecting to the platinum resistance temperature sensor 1.

[0016] Furthermore, a spring 3, made of stainless steel, is provided between the insulating tube 2 and the handheld handle 4. In this embodiment, a stainless steel spring 3 is assembled between the handheld handle 4 and the insulating tube 2. When the handheld sensor applies pressure to the head of the platinum resistance temperature measuring chip 1, the spring 3 can effectively prevent it from being subjected to excessive force and causing the chip material to break. Moreover, it can ensure that the head of the platinum resistance temperature measuring chip 1 makes better contact with the surface being measured, thus ensuring the safety and reliability of the sensor.

[0017] Based on the above embodiment, the platinum resistance temperature measuring chip 1 is placed flat in the placement position, with a portion exposed above the placement position. The platinum resistance temperature measuring chip 1 adopts a flat-lying process, with the chip exposed approximately 20.1mm above the insulating tube. During use, the user can allow the platinum resistance temperature measuring chip 1 to directly contact the surface being measured; an internal small spring 3 is designed to ensure better and smoother contact between the head and the surface being measured, while also ensuring that the pressure on the chip head is within a certain range (protecting the chip).

[0018] Furthermore, the outer surface of the handheld handle 4 is designed with an arc shape that is easy to grip. The design of the handheld handle 4 effectively ensures the safety and reliability of the sensor. Its arc shape and ergonomic design make it easy to hold and operate.

[0019] In this embodiment, the housing 5 is made of stainless steel. The housing 5 uses a lightweight yet robust and insulating material, such as high-strength engineering plastic, which reduces the overall weight while effectively protecting the internal components.

[0020] Based on the above embodiments, a fixing screw 6 is also included, which is used to fix the outer shell 5 and the hand handle 4.

[0021] The above provides a detailed description of a handheld platinum resistance temperature sensor provided by the embodiments of this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
