Where can I find sensors for the pyrolysis of industrial salts at temperatures ranging from 650°C to 1000°C and under pressures of 5–10 MPa?
Thread Content
Help: Enclosed stainless steel tank, operating temperature of 650°C, with a peak temperature of 1000°C. The internal pressure of the tank is 5-10 MPa. Used for cracking various hazardous chemical waste materials. Since it is heated by microwaves, there are electromagnetic waves inside the tank. It is necessary to monitor the temperature, liquid level, and pressure inside the tank; where can one find sensor products suitable for such conditions? I ask all the teachers for their help.
Temperature is easy to handle; use whatever material is used for the tank to make the temperature sleeve as well. The best approach for the others is to cool them down; otherwise, nuclear weapons will be needed to control the liquid level. Will it solidify if the temperature drops below 400 degrees? It can be measured without solidification creep.
Breaking down industrial salt – this process is really amazing; purifying it through recrystallization allows one to sell it and make money from it

For liquid-phase pressure, if the liquid does not solidify when cooled, pipes can be used to transfer the pressure and cool it for measurement. If the liquid material solidifies upon cooling, such as in the case of molten salts, the gas collection and isolation method can be employed, along with pressure measurement using piping. 3. The liquid phase pressure and gas phase pressure; by using a pressure difference gauge, the pressure difference of the liquid column can be determined, and from this the height of the liquid column can be calculated. 4. Under high temperature and high pressure conditions, gases tend to dissolve in the liquid phase, resulting in unstable density of the liquid phase. In this way, converting the pressure difference into liquid column height often presents a challenge in terms of conversion accuracy. 5. In some high-temperature and high-pressure reaction systems, the key aspect of level measurement is not necessarily the accuracy of the level readings across the entire range; rather, it is the accuracy of the threshold value at which an alarm is triggered for the upper limit of the liquid level that is crucial! It is said that containers with excessive liquid levels are at risk of being scrapped. I encountered a situation where there was an error in the operation of the upper liquid level alarm threshold; the requirement is that this error should not exceed ±5 mm. 6. Refer to the following two diagrams.
Do we really have to make them several extra tall?
