Tedea Huntleigh / Model 355 Welded, Hermetically Sealed Load Cell

Tedea Huntleigh / Model 355 Welded, Hermetically Sealed Load Cell

The stainless steel load cell model 355 is a welded bending beam. Hermetically sealed against moisture, the 355’s construction and polyurethane shielded cable, enables the load cell to function in harsh environments while maintaining its operating specifications. The high accuracy, low profile and sealing makes the 355 suitable for applications such as weighing and packing machines, feeders, hoppers, platforms, and variety of other applications. The load cell is available in an EEx ia IIC T6 level approved version.
