Description

Model F1821 Compression force transducer

Standard version to 100 kN

The model F1821 compression force transducer is suitable for harsh environmental conditions and available in measuring ranges to 100 kN. Its compactness enables a universal and reliable use in industry and laboratories.

This force transducer is easy to handle and its small dimensions predestine it particularly for use in narrow structures with limited space in which compression forces must be measured.
