The Mark V STAM - A Microcomputer for Acquiring Field Data

The Statistical Analog Monitor (STAM) was developed by the Fluid Power Research Center to gather information about the operational severity of hydraulic systems operating in the field. A new device, the Mark V STAM, has been designed using a single-chip microcomputer. This device promises to provide more accurate data and new flexibilities in configuring tests.

This paper discusses the STAM concept and the theory of operation of the Mark V STAM hardware. The application of the STAM is illustrated with actual results from a vehicle operated in three different conditions.
