A load cell is a force sensing module - a carefully designed metal
structure, with small elements called strain gauges mounted in precise
locations on the structure. Load cells are designed to measure a specific
force, and ignore other forces being applied. The electrical signal
output by the load cell is very small and requires specialized amplification.
Fortunately, the 1046 PhidgetBridge will perform all the amplification
and measurement of the electrical output.
Load cells are designed to measure force in one direction. They will
often measure force in other directions, but the sensor sensitivity
will be different, since parts of the load cell operating under compression
are now in tension, and vice versa.
This Single Point Load Cell is used in small jewelry scales and kitchen
scales. It¡¦s mounted by bolting down the end of the load cell where
the wires are attached, and applying force on the other end in the
direction of the arrow. Where the force is applied is not critical,
as this load cell measures a shearing effect on the beam, not the
bending of the beam. If you mount a small platform on the load cell,
as would be done in a small scale, this load cell provides accurate
readings regardless of the position of the load on the platform.
