Mechanical Scale
Conversions
There are two ways to convert older mechanical lever scales (see Figure 2-4) for
electronic weighing. The first method is a lever conversion. It involves adding an S-Cell
tension weigh module, while retaining the levers and weighing platform from the existing
mechanical scale. The second method is a lever replacement. It involves removing the
levers and adding compression weigh modules beneath the existing weighing platform.

Lever Conversion
A lever conversion retains the mechanical scale’s dial head, so that the scale can be
used for electronic or mechanical weighing. An S-Cell tension weigh module is inserted
into the existing steelyard rod located in the column of the dial head. The dial head is
locked out to allow the S-Cell to sense the tension load applied by the transverse lever
that extends from the scale pit. In case of a power or load cell failure, the dial head can
be unlocked for fully mechanical operation. Figure 2-5 shows a lever conversion.
