2.1 Overview
2.2 Description
The single point load cell is intended for the measurement of static compression forces
in weighing applications. The single point load cell consists of a measuring spring on
which strain gauges (SGs) are applied.The measuring body is made of aluminium
and is elastically deformed by a force introduced in the force direction.The resulting
mechanical tensions are measured by the strain gauges and output as an electrical
output signal.
The strain gauges are arranged so that two of them are tensioned and the other two are
compressed when a force is applied to the single point load cell.
The single point load cell circuit includes correction and compensation resistors to elimi-
nate unwanted effects on the zero signal and characteristic value.
