The performance of the weighing cell depends exclusively on the synergy between the technical design and the introduction of the load.

There are offers with compression weighing cells (not recommended) and capacity 20t / cell.
20t x 4 weighing cells mounted on a section of the platform = 80t
The weight of the 20t platform section + the maximum loaded truck 60t = 80t
It turns out that the weighing cells operate at the upper limit of the load, where the hysteresis curve is not linear.
The capacity of 30t / cell is the only one that places the operation in the middle of the range (50..60%) where this curve is perfectly linear! 30t x 4 = 120t > > 60..80t

All weighing cells use semiconductor strain gauges with column linearization, except those that use A / D converters. There are no particular advantages in favor of any solution.
Hysteresis performance and creep depend on:

• Choice of material
• Selecting Tensometric Marks
• Heat treatment

Best practice is to use stainless steel alloys, tensometric marks with negative hysteresis (to compensate for residual positive hysteresis after heat treatment) and a comprehensive heat treatment process.
Each ROCKER COLUMN cell is individually tested for creep.

Calibration values ​​mV / V / ohm and mV / V are a determining factor in the selection of weighing cells. The importance of these values ​​is twofold:

1. Cells can be replaced without the need to readjust corners or sections.
2. Cells can be replaced without the need to recalibrate the weighing system.

The way the load is inserted into the structure of the weighing cell is as important as its actual design. ROCKER COLUMN cells are constructed with convex-spherical load-bearing surfaces for the insertion of the load, appropriately spaced from the tensometric marks, to avoid the forces propagated from the areas of maximum effort.

A true ROCKER COLUMN weighing cell has two radial loading surfaces, one with a large radius in the center where the load is measured and another with a smaller radius at the ends where the rocking takes place ("rocker" = rocker). br This design provides the best introduction to the task invented in the world to date by the founders of FLINTAB Sweden, transformed into the international group FLINTEC.
FLINTAB Romania has taken over the entire know-how of the group.

As the ROCKER COLUMN weighing cell is balanced (as it is called), the forces generated by the expansions and contractions of the weighing platform are easily taken over by this balance. Similarly, errors caused by platform deflection (bending at a larger arrow) are minimized.
ROCKER COLUMN weighing cells are electrically compensated for accurate measurement when the cell has been rocked in a non-vertical position.
