How to measure the temperature of the medium in a double-layer container
Thread Content
A small container is placed inside the pressure vessel, and that small container contains metal powder. The small jars also move around often. What are some good ways to measure the temperature of the powder inside in this situation? The temperature of the powder is quite high; it requires a heating device outside the container to raise it to over 600 degrees before it stops rising. Do you all have any good ways to teach me?
Hehe, “The small container often needs to be moved.” I don’t understand why it needs to be moved. Let’s talk about the heating method inside the container as well – it needs to be explained clearly. Measuring temperature isn’t difficult; just explain it clearly, and I won’t make you send a red envelope. I’ll teach you a trick for measuring temperature :P
It is a horizontal container with a quick-opening design; the small containers inside need to be removed axially frequently after experiments, so it is difficult to fix instruments along the circumferential direction of the container. The container is 20 meters long in the axial direction; I am considering inserting several long protective tubes with thermoresistors into the container’s head, connecting them to the tank, so that the thermoresistors come out along with the tank when it is removed.
This plan should work. For production equipment that is used repeatedly over a long period of time, it is possible to install several thermocouples inside the vessel; by obtaining data from these thermocouples, it becomes unnecessary to measure the temperature inside the vessel, as long as it is known for how long the temperature in the interlayer remains consistent with that of the vessel interior. Additionally: Thermal resistors at 600°C are often not reliable; thermocouples are more dependable. Moreover, with electric heating, it is more difficult to resist interference from thermal resistance compared to using thermocouples.
