Compression Load Cell (CSPM)
Product Information
The Model CSP is a multi-column, low proile, stainless steel compression load cell. The unique four column design offers excellent insensitivity to eccentric loads while maintaining accuracy.
This product is suitable for use in road and rail weighbridges and process weighing applications.
The fully leak-tested welded construction, advanced cable entry, and built-in surge protection tubes ensure that this product can be used successfully in demanding environments.
This product meets the stringent Weights and Measures requirements throughout Europe.

FSO—Full Scale Output
SC-version: The rated output and the output resistance are balanced in such a way, that the output current is calibrated to within 0.05% of a reference value. This allows easy parallel connection of the load cells.
