Weight measuring transducers are constructed from 3 distinct components. Tool Steel, Aluminum, or Stainless Steel.
Tool steel elements are quite possibly the most preferred load cells used nowadays. The cost-to-performance proportion is superior, in comparison to other materials used in load cell structure. Typically the most popular alloy used is 4330. Tool steel load cells are relatively inexpensive, have a big capacity selection and are best utilized in dry purposes.
Aluminum is largely found in single point, small capacity uses. Aluminum is the cheapest of the three materials useful to produce load cells. Aluminum transducers are limited by their low capacity array and ought not come in contact with wet or chemical conditions.
The third material employed for load cell manufacturing is stainless-steel. This alloy has the best overall performance of any of the stainless derivatives. Stainless steel load cells are more expensive than tool steel or aluminum, but their amount of resistance to corrosion ensures they are a great alternative in moist or harsh purposes.
Another important item to take into consideration when designing a weighing system is just how the load cell's internal elements are guarded from the environment.
Environmentally sealed is employed to spellout various techniques, but in the end is achieved by one or more of the following: rubber boots, glued on covers or potting the gauge cavity of the load cell. This sort of sealing will safeguard the load cell from harm attributable to debris and dust and mild humidity caused by splashing of water. In no way will the load cell be protected from immersion under water or being exposed to high pressure cleaning. One more sealing technique used on load cells is hermetically sealed. This incorporates a welded cover or sleeve that encapsulates the gauge pocket. The load cell cable entry area also implements a welded barrier to prevent moisture from wicking in to the load cell, and shorting it out. This technique is mostly utilized on stainless steel load cells as a stainless, hermetically sealed load cell should only be used in heavy wash down or chemical applications. This tends to make for a more costly load cell but if extended life in a hostile environment is sought after, this is the most cost effective answer ultimately.
A welded seal loadcell is similar to a hermetically sealed cell, with the exception of where the load cell cable comes out. A welded seal cell usually has the same load cell cable connection as the environmentally sealed cell. In some instances, the welded sealed cell may have a conduit adapter for the load cell cable, affording some degree of protection. While the gauge area itself is guarded by the welded seal, the cable entry is not. Welded sealed load cells are to be used where the cell may get wet on occasion, but are not meant for heavy wash down purposes.
