Abstract
A position sensor assembly for the hydraulic cylinder having a piston and piston rod is provided. The position sensor assembly includes a pressure to electric energy convertor, a transmitter and a receiver. The pressure to electric energy convertor is disposed inside the piston. The pressure to electric energy convertor is configured to determine pressures on both the sides of the piston and convert the determined pressure difference into electric current. The electric current is consumed by the transmitter and hence, the transmitter generates a signal. The signal is wirelessly transmitted to the receiver through the hydraulic cylinder. The receiver disposed on the hydraulic cylinder receives the signal through various components of the hydraulic cylinder. The signal is used to determine the position of the piston.
