Abstract
A system and for determining health of a fluid seal member including a fluid seal member; a transducer in force transmitting contact with the fluid seal member to generate an output signal based on an amount of force and/or pressure applied to the transducer; a radio frequency (RF) transponder operably coupled to the transducer to store the output signal of the transducer; a reader within an operable distance from the RF transponder to transmit electromagnetic energy to the RF transponder and receive the output signal of the transducer stored in the RF transponder through a radio frequency communication link; and a processor coupled to the reader, to determine health of the fluid seal member.
Claims22
A system for determining health of a fluid seal member, the system comprising:
- a fluid seal member;
- a transducer in force transmitting contact with the fluid seal member, wherein the transducer is operable generate an output signal based on an amount of force and/or pressure applied to the transducer;
- a radio frequency (RF) transponder operably coupled to the transducer, wherein the RF transponder is configured to store the output signal of the transducer;
- a reader within an operable distance from the RF transponder, wherein the reader is selectively controlled to transmit electromagnetic energy to the RF transponder and receive the output signal of the transducer stored in the RF transponder through a radio frequency communication link;
- and
- a processor coupled to the reader, wherein the processor is operable to determine health of the fluid seal member based on the received output signal of the transducer, wherein the processor correlates the received output signal to a compression set and determines health of the fluid seal member by the amount of compression set imparted in the fluid seal member.
A method for determining health of a fluid seal member, the method comprising:
- measuring force and/or pressure transmitted to the fluid seal member by a transducer in force transmitting contact with the fluid seal member and outputting an output signal corresponding to the measured force and/or pressure;
- storing a representation of the output signal in a radio frequency (RF) transponder coupled to the transducer;
- reading the representation of the output signal stored in the RF transponder by a reader, wherein the reader is selectively controlled to transmit electromagnetic energy to the RFID transponder and receive the output signal of the transducer through a radio frequency communication link;
- and
- processing the received output signal by a processor, wherein the processing includes determining health of the fluid seal member based on the received output signal of the transducer by correlating the received output signal to a compression set and determine health of the fluid seal member by the amount of compression set imparted in the fluid seal member.
