Abstract

A sensor system for determining a condition associated with a piston rod of a reciprocating system includes an interrogator system having a first antenna. The sensor system further includes a second antenna separated from the first antenna by an air gap distance. The second antenna is configured to be coupled to the piston rod of the reciprocating system. The second antenna is a patch antenna and is configured to communicate with the first antenna through a range of translational movement relative to the first antenna. The sensor system further includes a radio frequency sensor coupled to the second antenna. The radio frequency sensor is configured to be coupled to the piston rod of the reciprocating system, measure a characteristic associated with the piston rod of the reciprocating system, and transmit data associated with the characteristic to the first antenna of the interrogator system through the second antenna.
