Abstract

The invention concerns a sensor system for monitoring a condition of a piston rod includes an interrogator system having a first coil winding coupled to a housing and radially spaced from the piston rod such that a gap is defined between the first coil winding and the piston rod. A second coil winding is coupled to the piston rod and is inductively coupled to the first coil winding. The second coil winding is configured to communicate with the first coil winding through a range of linear movement of the piston rod relative to the housing. A sensor is coupled to the second coil winding. The sensor is configured to measure a characteristic associated with the piston rod and generate a current in the second coil winding to transmit, via the inductive coupling with the first coil winding, an electrical output signal associated with the characteristic to the interrogator system.
