Self-contained digital electronic force gage with interchangeable force sensor modules

摘要

An apparatus for measuring compressive and tensile forces over extended incremental ranges of force loads utilizing freely interchangeable pre-calibrated force sensors (load cells) of various capacities each mounted integrally and permanently in a force cell module or housing which readily attaches and detaches to a force display module. The force display module employs an electronic microprocessor circuit to process the signal from the force sensor and to display the signal in units of force on an electronic display (liquid crystal display). The two modules comprise the complete self-contained digital electronic force gage (dynamometer) with all components mounted internally. The gage can be utilized as a hand-held unit or on a test stand or test fixture.
