A load cell is an electronic device (transducer) that is used to convert a force into an electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals.
A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer.
The LC500 is a 500 or 1,000 kilogram (1100 or 2200 pounds respectively) force single point shear beam load cell. Mount one end of the load cell in a fixture of your choice and apply force to the other end. As the load cell bends under force the signal through the bridge changes in a way that can be sensed by electronics.
