full-scale calibration.
Description
Omega's new LC103B S-Beam load cells are compact
and provide superior performance for tension or
compression loading. This design provides excellent
linearity and temperature performance, meeting OIML R60
C3 accuracy class for legal metrology applications.
Rugged stainless steel construction and precision sealing
provide anti-corrosion and IP67 ingress protection suitable
for all kinds of environments.
S-Type load cells that receive tension or compression
forces. Applications include tank weighing, hoppers,
suspended loads and truck scales. S-Type load cells
provide superior performance in a compact, versatile
package.
