Question for help: Selection of temperature sensors to be used in high-pressure reactors
Thread Content
I need to measure the temperature in a high-pressure reactor, where the pressure reaches 15–16 MPa. I’m using a PT100 temperature sensor with a probe of 3 mm in diameter. I’ve consulted several manufacturers, and they all say that such sensors cannot be used under such high pressures, or they’re not sure whether they can withstand it. So I would like to ask everyone if there are any suitable temperature sensor manufacturers that you can recommend, or how this issue should be resolved
Ordinary thermometers are usually placed in a thermometer sleeve. The pressure is determined by the sleeve.
Temperature sensors cannot withstand high pressure, so they are usually placed in sleeves, which also facilitates maintenance without shutting down the system.
For EVA equipment, high-pressure thermocouples from BASF and TE are used; they are sleeveless and can handle pressures of over 200 MPa. You can ask for more details.
Use a PT100, placed inside a sleeve. Requirements such as ease of replacement and high-pressure resistance.
Both sleeves and patches are solutions; for a rough measurement, infrared temperature measurement of the wall can also be considered~~~
