What is beam load cell?
GALOCE brand - beam load cell is divided into parallel beam load cell, shear beam load cell, cantilever beam load cell, planar beam load cell and S beam load cell. The parallel beam load cell and shear beam load cell are widely used and have a lot of commonness and individuality.
The commonness of parallel beam load cell and shear beam load cell
When the beam type load cell is used, one end is fixed and the other end is stressed.
Such a measurement method has a high output sensitivity, high precision and other characteristics of measurement, so it has been widely used. However, there are two production processes in this method, parallel beam load cell with upper and lower parallel patch, and shear beam load cell with side wall V patch.
The individuality of parallel beam load cell and shear beam load cell
The difference between the two is that the upper and lower parallel patch of parallel beam load cell, measures the relative change of the upper and lower plane, thus allowing greater bias.
The shear beam load cell adopts the side V patch technology, which measures the deformation of the cross section.
The reference point for comparison is the upper part and the lower part of the cross section.
Thus, the output millivolt signal of the shear beam is slightly less than that of the parallel beam in the same shape variables.
However, due to the less damage of shear beam to elastomer material, this kind of sensor is superior to the parallel beam load cell in terms of transient impact and overload.
When using by the user, if the bias is large, the parallel beam load cell can be used.
For example, kitchen scale, simple small table scale, belt scale, the advantage is that a parallel beam load cell can form the platform scale.
The shear beam load cell is not, and its use must be in accordance with its specified stress point and stress direction.
Most of the small range shear beam load cell are made of aluminum alloy. If alloy steel materials can be made into the side and other forms.
