LOAD LIMITER

Limitation of the detected load through alarm and pre-alarm levels.

Overload control with double-security system by connecting two units.

Limitation of load (single and sum) for weighing systems up to 4 points, by connecting more units.

Load cell fail alarm and Set-up and calibration via keyboard and display board removable.

Load cell mounting

General guidelines for installing and mounting load cells:

Respect the direction in which forces are applied to the load cells
Do not exceed the temperature limits shown on the rating plate
Do not remove the labels from the cells
Protect cables properly with sheaths or cable ducts
Connect each cell to earth with a suitable cable, bridging the plates of the mounting accessories if necessary
Do not weld on the mechanical structure once the cells are in place
Avoid or minimise mechanical constraints between the fixed structure and the weighed structure, to prevent weighing errors and zero return problems
When vibrations or dynamic loads are present, protect the cells with anti-vibration mounts
Protect the cells from dust build-up with suitable covers
