Abstract

An instrumentation system for measuring forces during tool and die forming operations including a load cell positioned in a well bored into a base plate. The plate includes a series of channels that carry wiring from the load cell to the periphery of the base plate. The load cell is preferably mounted flush with a supporting surface of the base plate to facilitate periodic cleaning. The load cell includes sensors generating a signal corresponding to the force or compression on the load cell. The load cell also includes apertures extending therethrough to allow existing tooling to be mounted on the load cell to the base plate via fasteners and pins extending through the load cell to the base plate. An universal load cell embodiment includes a pattern of apertures allowing two or more tools having unique hole patterns to be mounted on the load cell with fasteners and pins extending therethrough.
