Selection of a level gauge with stirring function for high-temperature environments in modified asphalt reaction kettles
Thread Content
It’s a reactor with a temperature of around 420°C and it has an agitator. The side of the reactor cannot be opened due to process requirements; currently, we are considering installing a level gauge on the top. Do any experts have any recommendations?
Radiometric level gauges are possible, but the safety requirements are too high. It is likely that the radar will move around randomly; therefore, it might be a good idea to use a protective sleeve for the radio frequency admittance.
Does radio frequency admittance require running a cable and probe to the bottom? With such high temperatures and stirring involved, plus the high viscosity of asphalt, it’s likely not suitable.
Are you sure this method will work? Gas can get in, but can it come out smoothly? Were you sent by the second senior brother?
Can a model with a stirrer be equipped with a protective tube? Will it coagulate if the viscosity is high?
Reactor vessels for polymer materials are also in use, and the viscosity of those materials is much higher than that of modified asphalt.
