What should be used as the heat transfer medium for the thermometer sleeve?

The thermometer probe is inserted at an upward angle into the pressure vessel; it consists of a armored thermoresistor, and there is approximately a 1–2 mm gap between the thermometer and the bottom of the probe. What type of heat transfer medium would be suitable?
This is usually empty, and it’s not suitable for holding liquids with the opening facing downward.
That’s why I’m struggling. Are there any paste-like heat transfer media?
That can’t be right; the temperature sensor should be inserted all the way in, right? How can there be gaps?
No additional substances are needed, but the thermal response time will increase
Even if it’s inserted all the way in, it only makes slight contact, so the temperature response is slow
That’s useless. Just like how they use mercury thermometers at the entrance of hospitals to take temperatures, everyone has to have their temperature taken for 10 minutes
If there is a protective sleeve, it is best for the sensor to be designed with a spring； There’s already a gap now, and nothing can be done about it; just apply some thermal paste. We advise our customers to wait until the next day – it only costs a few dollars
Is the sleeve oriented upward or downward? If it faces upward, silicone oil cannot be used; instead, a high-viscosity silicone grease must be used ； Downward, it doesn’t matter. Using silicone oil or grease is only a temporary solution; it deteriorates quickly at high temperatures, its thermal conductivity decreases, and it becomes sticky, making it uncomfortable to insert sensors into it. Additionally, this image with an upward slope has a strong symbolic meaning
