Canister cell popularity is waning as their cost is 2 or 3 times
that of a bending beam cell. There are two types of canister
construct ion, single column and multiple column.
Single-column canisters cannot normally withstand a side
load of over 15%. Multiple column canister cells withstand
more side load than the single-column variety. The canister
cell ranges in size from 100lbs up to 500,000lbs. The normal
safe overload is 150% of full scale (F.S.) but some models are
able to withstand a 300% F.S. overload. There is no means
through visual inspection or labeling to identify which cells are
singular or multiple column. Refer to original manufacturer’s
specifications or Rice Lake Weighing Systems’ Load Cell
Guide to determine your cell’s specifications.
Canister cells are made of high alloy tool steel with an epoxy
finish, or stainless steel. Their rated excitation ranges from
10VDC to 20VAC/DC. Common bridge resistances are 350Ω
