High level switch for hydrated lime silo
High level switch for hydrated lime silo
(OP)
We have an application where we overfilled a hydrated lime silo. The silo has a guided radar level probe but in this instance the level jumped rapidly from 80% to 100% and the silo overflowed before the operator could shut off the lime supply. The silo is relatively small (70m3) and holds less than a full truck of lime. The hydrated lime is pneumatically blown into the silo.
One of the possible mitigating actions is to install a high level switch in the silo. Does anyone have experience with high level switches (or other indications) in this type of application? The hydrated lime density is very low- only 350kg/m3 when settled and lower when just blown (it flows like water when fluidised).
Cheers,

Hope this help.

I've had some other feedback along similar lines- installing a high level switch (vibrating tuning fork) inside the silo
