Description

Technical Field

[0001] The utility model belongs to the technical field of resistance detection, and relates to a switching system for platinum resistance detection, in particular to a switching system for platinum resistance detection in a vacuum environment. Background Art

[0002] In the field of vacuum technology, vacuum tempering furnaces are common equipment used primarily for heat treatment of metal materials. During heat treatment, the temperature within the furnace must be precisely controlled, necessitating the use of a platinum resistance thermometer (RRT). A platinum resistance thermometer is a high-precision temperature sensor whose resistance changes with temperature. By measuring this resistance, the furnace temperature can be determined.

[0003] However, platinum resistance sensors require electrical connections to transmit signals to external detection equipment, which requires the use of adapters and sealing devices.

[0004] In the field of resistance testing technology, platinum resistance testing equipment is a common device used to measure the resistance value of platinum resistors. This device usually needs to be connected to the platinum resistor through an electrical connection, and then the resistance value of the platinum resistor is obtained by measuring the circuit inside the device.

[0005] In the field of mechanical connection devices, adapters are a common device used to connect different components. In vacuum tempering furnaces, adapters are used to connect platinum resistance sensors and external detection equipment to achieve signal transmission.

[0006] Existing Solutions: A common solution is to use vacuum-sealed connectors to connect platinum resistors to detection equipment outside the vacuum tempering furnace. This approach maintains the vacuum environment within the furnace while also enabling signal transmission. However, this method requires four wires to be threaded through each platinum resistor, making it complex and inefficient. Furthermore, the sealing method requires the installation of multiple sealing rings, which can easily lead to vacuum leaks.

[0007] Another solution is to use a built-in platinum resistance detection device, which can be directly installed in the vacuum tempering furnace and then connected to the platinum resistor through an electrical connection. This method can simplify operation and improve efficiency, but it is expensive and difficult to maintain. 3) Problems with existing technologies: There are some problems with existing technologies in practical applications. First, the method of threading each platinum resistor is complicated to operate, inefficient, and prone to errors, which affects the accuracy of temperature control. Secondly, the built-in platinum resistance detection device is expensive and difficult to maintain, which is not conducive to large-scale application. In addition, it is difficult to ensure the airtightness of these two methods, which may affect the normal operation of the vacuum tempering furnace.

[0008] Therefore, the present invention proposes a switching system for platinum resistance detection in a vacuum environment, which can overcome the above problems.

[0009] After searching, no public documents of the prior art that are identical or similar to the present utility model were found. Utility Model Content

[0010] The purpose of the utility model is to overcome the deficiencies of the prior art and to propose a switching system for platinum resistance detection in a vacuum environment, which can avoid temperature control errors caused by complex operation or equipment failure while ensuring temperature control accuracy.

[0012] A transfer system for platinum resistance detection in a vacuum environment, comprising: a double-sided transfer flange, a double-sided sealed transfer joint, a sealed transfer terminal, a platinum resistance detection device, and a platinum resistor;

[0013] One end of the double-sided adapter flange is connected to the platinum resistor in the vacuum tempering furnace, and the other end is connected to the platinum resistor detection equipment outside the vacuum tempering furnace, so as to connect the electrical signal of the platinum resistor to the platinum resistor detection equipment outside the vacuum tempering furnace;

[0014] Moreover, the double-sided adapter flange has a vacuum sealing structure, including: a sealing flange; a plurality of double-sided sealing adapters are installed on the sealing flange, and the plurality of double-sided sealing adapters are all pressed and fixed on the sealing flange through sealing grooves and sealing rings; one end of the double-sided sealing adapter is connected to the platinum resistor in the vacuum furnace through a sealing adapter terminal; the other end of the double-sided sealing adapter is connected to the platinum resistor detection equipment.

[0015] Moreover, the double-sided sealing adapter is made of a ceramic body or fused quartz, and the conductive pins are sintered on the ceramic body.

[0016] Moreover, the platinum resistance detection device adopts an external direct-insertion platinum resistance detector.

[0017] Moreover, the double-sided adapter flange is installed on the test cavity.

[0018] Moreover, the sealed transfer terminal is a four-wire connection.

[0019] Advantages and beneficial effects of the utility model:

[0020] 1. The present invention proposes an adapter system for platinum resistance detection in a vacuum environment. First, the present invention connects the platinum resistor in the vacuum tempering furnace through a double-sided sealed adapter with vacuum sealing, thereby ensuring the vacuum environment in the furnace while also achieving efficient signal transmission, greatly improving the accuracy and efficiency of temperature control. Secondly, the present invention connects the electrical signal to the platinum resistance detection equipment outside the vacuum tempering furnace through a four-wire sealed adapter terminal, avoiding the tedious operation of threading each platinum resistor, reducing the complexity of the operation, and improving work efficiency. In addition, the external direct-plug platinum resistance detector of the present invention makes the maintenance of the equipment more convenient and reduces the maintenance cost. Therefore, the present invention not only meets the temperature control requirements of the vacuum tempering furnace, but also meets the use requirements of the resistance detection equipment, and has broad market prospects.

The conductive pins are sintered on the ceramic body inside, which can ensure that gas will not leak from the adapter in a vacuum environment, thereby ensuring the airtightness of the vacuum tempering furnace.

[0038] In this embodiment, the electrical signal of the platinum resistor is connected to the platinum resistor detection equipment outside the vacuum tempering furnace through a sealed adapter terminal.

[0039] In this embodiment, an external direct-insertion platinum resistance detector is used. The instrument can be directly inserted into the sealed adapter terminal without the need for complicated wiring work, which greatly simplifies the operation process and improves work efficiency.

[0040] In this embodiment, a modular design concept is adopted so that each part of the platinum resistance detection device can work independently or be combined according to actual needs, thereby reducing the cost of the device and making it more suitable for large-scale applications.

[0044] 3. Reduce costs: Compared with built-in platinum resistance detection equipment, the utility model adopts an external direct-insertion platinum resistance detector, which does not need to be built into the vacuum tempering furnace, reducing equipment costs and maintenance difficulties.

[0047] The working process of this utility model is:

The adapter's internal design features a special sealing structure to prevent gas leakage in a vacuum environment. Specifically, the adapter is constructed from a high-temperature, corrosion-resistant ceramic body or fused quartz, with conductive pins sintered to the ceramic body, ensuring a strong seal even under high pressure.

[0049] Step 2: Place the platinum resistor in the vacuum tempering furnace and connect the resistance's electrical signal to the platinum resistor detection equipment outside the vacuum tempering furnace via a sealed adapter terminal. Specifically, the sealed adapter terminal is made of a special high-temperature and corrosion-resistant ceramic. Its internal design ensures good electrical contact under high voltage. The adapter terminal provides a four-wire connection, which can meet the needs of various measurement methods.

[0050] Step 3: Use an external direct-plug platinum resistance tester. This instrument can be directly inserted into the sealed adapter terminal, eliminating the need for complex wiring. Specifically, the tester's interface is designed as a standard direct-plug type and can be directly inserted into the sealed adapter terminal without any additional connectors or cables.

[0051] Step 4: Using a modular design approach, each component of the platinum resistance tester can operate independently or be combined as needed. Specifically, each component of the device, such as the power module, signal processing module, and display module, can operate independently or be combined as needed, thereby reducing the cost of the device and making it more suitable for large-scale applications.

Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the utility model also fall within the scope of protection of the present invention.
