Abstract

A machine monitoring system (100) is provided. The system includes a housing (102) mounted to a surface (108) of a machine (106), a plurality of sensors (110) configured to monitor a parameter of the machine and generate respective output signals (202), the parameter indicative of a condition of the machine, a voting module (116) positioned within the housing and configured to receive the respective output signals and generate a corrected output (206) based on the respective output signals, a memory device (118) positioned within the housing and including a store location configured to store manual input functions (210) relating to a construction of the machine, a life calculator (120) positioned within the housing and communicatively coupled to the voting module and the memory device, the life calculator configured to determine a life remaining in the machine using the corrected output and the manual input functions, and a display (122) positioned within the housing and configured to display (214) the life remaining in the machine.

Description

technical field [0001] The field of the invention relates generally to machine condition monitoring, and more particularly to methods and systems for monitoring the remaining life of a machine in near real time using the monitored condition of the machine. Background technique [0002] In at least some known industries (such as, but not limited to, the oil, gas, and electric industries), critical equipment must operate at its maximum capacity during periods of peak demand in order to benefit from specified market conditions, e.g. The price of electricity and the price of electricity per kilowatt-hour are higher. [0003] Based on available data, one of the top causes of equipment unavailability is downtime due to scheduled maintenance. Often, such maintenance is not required by the condition of the equipment, but is dictated by timing requirements. By enabling condition-based maintenance, non-value-added inspections and maintenance can be reduced, if not completely elimina...
