Claim 28:
29. A system for analyzing seal life, comprising:
at least one memory for storing computer-executable instructions; and
at least one processing unit for executing the instructions stored in the memory, wherein execution of the instructions programs the at least one processing unit to perform operations comprising:
engaging a valve assembly movable from an open position to a closed position, to place the valve assembly in operation, wherein the valve assembly comprises a seal having elastomeric properties, a door configured for covering an opening in a process chamber and a valve for operating the door from the open position to the closed position and the seal contacts the door, wherein the seal is seated within the valve and in contact with a surface of the valve assembly, and wherein pressure is applied to the valve assembly in operation and the seal is subject to degradation;
receiving from a circuit a signal from a change in voltage, wherein the circuit is in communication with at least one sensor for measuring micro strain on an exterior surface of the door of the valve assembly or within the valve assembly;
recording micro strain data and at least one other property related to a condition selected from an ambient condition of operation and a condition related to degradation of the seal after operation of the valve assembly is initiated; and
analyzing the recorded data against baseline data associated with 100% seal life to evaluate seal life at the time after the operation of the valve assembly is initiated as a percentage of seal life less than 100%.
