Problems with RF admittance level switches
Thread Content
What are the operating conditions for radio frequency admittance level switches? What factors should be considered when making a choice? Does conductivity need to be considered? If it is needed, how is it considered for using that coal powder silo?
In my opinion, the setting of radio frequency admittance should be determined by the upstream specialty (the process engineering team). When making a choice, factors such as accuracy, range, operational density, temperature, and pressure need to be considered. This kind of thing is used less often.
The material level in powder silos has always been a problem; it’s difficult to determine the level of any type of material
RF switches can be used for measuring materials such as conductive and insulating slurries, powders, and particles. When selecting one, factors such as the temperature, pressure, dielectric constant of the medium being measured, probe length, and installation method must be taken into consideration. The use of radio frequency admittance switches in coal powder silos takes advantage of the strong versatility, easy installation, and high measurement accuracy of such switches.
Measuring, it’s just like having a bowel movement – you sit on the toilet, and that’s it. With all that in mind, what’s the point of taking any tests?? It’ll just blow out the anus and ruin the pants, causing everything to spill out. :P
There’s no problem with the coal powder silo; it’s essential to choose products from reputable manufacturers, as otherwise they may not work well. It turns out it has been used in both the limestone powder silo and the fly ash silo
If there is concern about false alarms due to material sticking during blanking, a cover such as angle steel can be placed above the level gauge. This refers to installation in a horizontal orientation; this problem does not exist with vertical installation.
