Application

2.1.1

Base plate and elastomer bearing

The self-centering elastomer bearing for SIWAREX WL230 BB-S SA load cells is particularly
suitable for installation in roller table, platform and vessel weighing machines. The elastomer
bearing is firmly connected to the load cell and the load carrier. This provides a lift-off protection
to a limited extent.
The elastomer bearing is responsible for the direct transmission of force in the load cells.
The base plate fixes the load cell to the foundation.
The base plate and elastomer bearing have the following features:
● Easy installation of the load cell
● Self-centering effect on the load bearing implement
2.1.2

Use of the grounding cable

The grounding cable is used to protect the load cells from undesired currents. The causes of
such currents are, for example:
● Equalizing currents with missing or faulty equipotential bonding conductors
● A lightning strike nearby
● Welding work
● Static charge

Design

2.2.1

Design of base plate and elastomer bearing

The base plate and the elastomer bearing consist of the following components:
● Elastomer bearing
● Locking screw
● Base plate
Together with the load cell, the elastomer bearing represents a self-centering bearing unit.
