Miniature Load Cells

Model 31 Series

Miniature load cells. Rugged double diaphragm capacity: ≤100 lb: single diaphragm: >100 lb. Male thread attachments

Configure Product

Honeywell miniature load cells are designed to fit into systems with limited space or tight clearances. The Model 31 series are Honeywell's highest accuracy, rugged, miniature load cells designed to measure both tension and compression load forces from 50 g to up to 10,000 lb or 0.5 N up to 50,000 N, with high accuracies of 0.15 % to 0.25 % full scale.

The all-welded, stainless steel construction is designed to eliminate or reduce to a minimum the effect of off-axis loads. Can be completely welded for underwater applications. If you need special modifications or a complete custom design to meet your unique requirements, please contact us.
