DESCRIPTION:
Model 355 is a welded bending load cell manufactured in stainless steel. Hermetically sealed against moisture
the Model 355 construction and polyurethane shielded cable enables the load cell to function
in harsh environments while maintaining its operating specifications.
The low profile, high accuracy and sealing makes this load cell highly suitable for applications
such as low profile platforms, weighing and packing machines, conversion of mechanical scales
and variety of other applications where sealed cells are required.
For hazardous environments this load cell is available with EEx ia IIC T6 level of approval as an option.
The two additional sense wires feed back the voltage reaching the load cell. Complete compensation of change in
the lead resistance due to temperature change and/or cable extension, is achieved by feeding this voltage into the appropriate electronics.
