Description
Load cells QS-2NJ 20t
Basic device of the up-to-date weight measuring systems is load cells, construction of which is based on resilient mechanical member which is subject to deformation with overlaid on it strain-gauge bridge consisting of resistive-strain sensors connected in different electric networks.
With effect of external load to sensor as a result of deformation symmetry of measuring bridge is upset and electrical signal proportional to applied effect to sensor is appeared at measuring terminals.
Load cell QS-2NJ is one of the most popular models of load cells submitting by manufacturer USCells . It applies for railway and silo scales.
The present model of load cells possesses advantages such as explosion safety, impact resistance and high accuracy.
Brands/Trade Mark: USCells.
Application in rail weight scales, Silo scales.
Type of QS-2NJ is Double-Ended Shear-Beam Load Cells.
