A look inside the HC-i counting scale

One of the interesting features of A&D’s HC-i counting scale is its modular construction. The indicator can be separated from the base:

The following image lets you have a look inside the base of the scale. You can click on the tabs to highlight different elements and read a short description:

HC-i load cellThe load cell is attached to the bottom plate on one end and to the top plate on the other. It will slightly bend when a load is applied.
Strain gagesThe deformation of the load cell is measured by tiny sensors called strain gauges. If you look closely (or click on the image to see it in full size), you can see two of them on top of the load cell while two more are located on the bottom side.
Overload stopsThe overload stops prevent the load cell form deforming too far when a load beyond its capacity is applied. The two screws on the top are used to slightly tilt the top plate in order to adjust the overload gap between the plate and the 4 corner stops.
