general instructions
HOW IT WORKS
The load cell is a transducer that converts the force applied by the roller on the bearing, in a proportional electric signal
that will be processed by the control system, generally composed by a PLC or a dedicated panel and which adjust the
controlled parameters of the unit (brake, clutch, engine, …).
The cell body is an elastic system which bends under load. The elastic part of the cell has the shape of a lamella properly
dimensioned in function of the load, to which the strain gauges are glued, made up of small grids of constantan
filaments, Wheatstone-bridge connected for a precise calibration.
When, under load, the lamella flexes and stretches, the extensometers accordingly
vary their electrical resistance.
When feeding the load cell, the change in the electrical output signal will be
proportional to the deformation of the strain gauges, so to the load applied to the cell
itself.
The output signal is normally of a few mV: hence, if the load cell is farther than 5 m
from the control unit, it may be necessary to amplify the signal through an external
amplifier or an ampli-PCD housed in the cell.
