The role of thermocouple vacuum connector

    Thermocouple is the most common temperature measuring element. Because of its wide temperature measurement range, high temperature measurement accuracy, simple structure, and low cost, it is widely used in industry. But how to accurately measure the temperature in the vacuum chamber is a tricky problem. Why do you say that?

    Vacuum is a relatively special environment, and the temperature distribution of the same thermal field will be very different in the vacuum and the atmosphere. Because the gas is very rare in vacuum, heat exchange is mainly accomplished through heat conduction and heat radiation. The thermocouple is a contact temperature measurement method, and the temperature measurement probe needs to be well fixed with the measured object to ensure that the temperature measurement probe can quickly and accurately respond to temperature changes.

    The difficulty lies in how to ensure the flexible arrangement of temperature measuring probes and the airtightness of the vacuum chamber. We already know that thermocouples can be classified into many thermocouples with different graduation numbers based on different positive and negative materials. Then the corresponding thermocouple vacuum connector lead must be made of matching materials, which is a difficult point; how to quickly connect the thermocouple wire to the connector, especially when there are more temperature probes in the vacuum chamber, how to arrange and wire it? This is the second difficulty.

    Huipu Technology provides a perfect solution. Thermocouple vacuum electrode flange, the penetration part is made of thermocouple special material, the terminal adopts the most common OMEGA thermocouple connector on the market, and the vacuum side and the atmosphere side can be plugged and unplugged. If you need a higher density thermocouple channel, we can also customize it.
