Inventor(s) include Beek, Johan Van; and Kumar, Ramanan.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "A sensor for detecting a pressure difference of a fluid is disclosed, including: a housing having a first cavity, wherein the longitudinal axis of the first cavity defines a first end and a second end of the housing, and the first cavity communicates with the outside of the housing at the first end via a first fluid through hole and communicates with the outside of the housing at a position spaced apart from the first end via a second fluid through hole, and the housing is provided with an end element at the first end; a piston held inside the first cavity and can move between a first position and a second position along the longitudinal axis, wherein a flange is arranged on the circumferential outer side of the piston, and the flange is closer to the first end than the second fluid through hole; a spring positioned in the first cavity and can apply a force to the piston along the longitudinal axis, the sensor also has a piston position sensing assembly for sensing the relative position between the piston and the housing, and a circumferential gap through which fluid can flow is formed between the circumferential outer surface of the flange and the inner wall of the first cavity. The sensor has high sensitivity to fluid pressure difference. The invention also relates to a filter dryer."
