Height compensation of the support points

With this method, the output signals of all of the load cells are attuned to each other under a

load. To ensure that all of the load cells receive approximately the same load, spacer plates

are used to compensate the heights.

The output signals of the individual load cells correspond to the load distribution.

Proceed as follows to measure the output signals:

1. Disconnect the load cell wires SIG+ and SIG-.

2. Supply the load cells with power from the power supply.

3. Measure the output voltage between SIG+ and SIG- of each individual load cell.

4. Place spacing plates under the load cell bracket with the lowest value until the output

Overload protection

CAUTION

Irreparable faults and damage to the load cells

When using load cells with small rated loads, always provide overload protection in order to

protect the cells from becoming damaged. This applies both to the measuring direction and

the transverse direction.

If load cells are used beyond the maximum working load or the maximum transverse load,

this can cause irreparable faults and even fracturing of the load cell or the installation unit.

Overload protection in the measuring direction

Load cells can be protected against vertical overload by limiting the measuring path with

stops.

For load cells with high rated loads, the risk of an unintentional overload is not as great.

Possible additional loads can already be taken into consideration during the dimensioning of

the load cells.

Another method for protecting load cells from an overload is to over-dimension the load cells.
