Different Types of Load Cell Seals
Load cell seals are important aspects of protecting sensitive components. When selecting load cells, it’s essential to match the seal type to your environment, ensuring sufficient protection against moisture and particles.

Load Cell Seals
Hermetic, environmental and welded seals are designed for specific application types to inhibit dust, debris and moisture from entering the load cell. The method and material used to seal a load cell depend on your application needs. Unfortunately, if the correct method isn’t chosen, premature load cell failure may occur.
Welded Seal Load Cells
Welded seal load cells are protected against debris and some moisture, but aren’t airtight or suitable for heavy washdown. As the name suggests, these feature a welded seal around the internal components. Unlike hermetically sealed load cells, the cable entry doesn’t have a seal, which is why it’s not an optimal solution for heavy washdown environments.
Environmentally Sealed Load Cells
Environmentally sealed load cells protect electronics from dust, debris and moderate moisture. Although these can withstand splashes, they’re not ideal for heavy washdown applications. Environmental seals entail potting the cavity around the strain gauge before covering and using washers or O-rings around the cable’s entry point.
Hermetically Sealed Load Cells
Best suited for heavy washdown or corrosive environments, hermetically sealed load cells are air- and watertight. These load cells are constructed of stainless steel to prevent corrosion and have a seal around the electronics and cable entry, creating a protected system.
