These are used for the maximum and minimum level in silos
and mill hopper which contain powder or grain material
which can be cereals, plastic material, sand etc. In the SE-A
series the paddle turns at low speed which when in contact
with material stops turning causing a contact to switch.
In the SM 85 the functioning is caused by material pressing
on a rubber membrane which causes a micro switch positioned
internally to operate.
