Patent number: 11280636Abstract: A rotary position sensor is disclosed. The sensor comprises a first structure and a second structure. The first structure is rotatably coupled to the second structure by means of a bearing having a rotation axis. A dipole magnet is attached to the first structure with a direction of magnetic moment perpendicular to the rotation axis and a sensing unit is attached to the second structure and configured to measure the absolute position of the dipole magnet's rotation angle. The first structure comprises an alignment characteristic which is detectable on the outside of the rotary position sensor. The dipole magnet is attached to the first structure such that the alignment characteristic and direction of the magnetic moment of the dipole magnet have a defined angle of rotation relation on the first structure.Type: GrantFiled: July 9, 2018Date of Patent: March 22, 2022Assignee: Sensata Technologies, Inc.Inventors: Albert Ferdinand Zwijze, Paulus Thomas Johannes Gennissen, Sietse Abel Michiel Hendriks

Patent number: 10871413Abstract: A method of manufacturing a pressure sensor is shown, wherein the pressure sensor comprises a port element with a sealing structure and a membrane. Four strain gages will be attached to the membrane. The gages are used in a Wheatstone bridge to sense the fluid pressure. A first finite element action determines a first contour around the membrane central axis with equal compressive strain and a second contour around the membrane central axis with equal tensile strain wherein when fluid pressure is applied to the membrane strain on the first contour is opposite strain on the second contour. A second finite element action determines the four positions of the strain gages on the first and second contour such that the difference between the highest error signal and the lowest error signal at the output of the Wheatstone bridge is minimal under influence of parasitic forces.Type: GrantFiled: April 5, 2017Date of Patent: December 22, 2020Assignee: SENSATA TECHNOLOGIES, INC.Inventors: Albert Ferdinand Zwijze, Werner John Peter Kleissen, Frank Hendri Jacobs, Dedde Hedzer Wiersma

Patent number: 9134384Abstract: Position sensor (10) for determining a linear position in a sensing direction, e.g. for application in a vacuum actuator. The position sensor (10) has a first sensor part and a second sensor part moveable with respect to each other. The first sensor part comprises an annular magnet (2) and a magnetic field sensor (3) positioned at a first distance (11) from the annular magnet on the magnet axis (1a). The second sensor part comprises a flux shaper (1) moveable through the annular magnet (2) along the sensing direction between a first and a second position, in the first position the flux shaper being substantially at the first distance (11) from the magnetic field sensor (3). The flux shaper is arranged to influence the magnetic field in a space between the annular magnet (2) and the magnetic field sensor (3).Type: GrantFiled: April 18, 2013Date of Patent: September 15, 2015Assignee: Sensata Technologies, Inc.Inventors: Albert Ferdinand Zwijze, Paulus Thomas Johannes Gennissen, Michiel Boersma, Jeroen Martinus, Roger Appelo

Patent number: 8935961Abstract: A sensor assembly includes a rectangular-shaped pressure sensor element and an electronic circuitry coupled to receive a signal from the pressure sensor element. An open-ended fluid-tight passageway of the sensor assembly conveys fluid from a portal opening of the sensor assembly to a surface of the rectangular-shaped pressure sensor element. The sensor assembly further includes a closed-ended fluid-tight passageway, at least a portion of which is fabricated from metal. The closed-ended fluid tight passageway extends from at least from the portal opening of the sensor assembly to the electronic circuitry on at least a portion of a path adjacent to the rectangular-shaped ceramic pressure sensor element. The sensor assembly includes a temperature sensor element disposed in an end of the closed-ended fluid-tight passageway. Conductive links disposed in the closed-ended fluid tight passageway electrically couple the temperature sensor element to the electronic circuitry.Type: GrantFiled: August 10, 2012Date of Patent: January 20, 2015Assignee: Sensata Technologies, Inc.Inventors: Nicholas G. Papadeas, Jeffrey Peter Silveria, Omar Rashid Ghani, Jared E. Girroir, Albert Ferdinand Zwijze, Paulus Thomas Johannes Gennissen, Edward Norberg
