Patent number: 9863436Abstract: A pump housing has a spiral housing and includes a suction channel (14) which runs out in a space (15). The space (15) is for arranging an impeller (6), rotatable about a rotation axis (5), and includes a spirally peripheral channel (16) open to the space (15) and running out into a pressure channel. A receiver (20) for a differential pressure sensor is provided within the pump housing. A first sensor channel (22) is provided, which connects the receiver (20) to a pressure-side interior of the pump housing. A second sensor channel (23) connects the receiver (20) to the pressure-side interior of the pump housing. The receiver (20) for the differential pressure sensor is arranged between the spirally peripheral channel (16) and the suction channel (14), so that the channels can be formed by way of simple bores.Type: GrantFiled: January 17, 2013Date of Patent: January 9, 2018Assignee: GRUNDFOS HOLDING A/SInventors: Casper Pedersen, Nicholas Pedersen

Patent number: 7823456Abstract: A pressure sensor is provided with a carrier (2), which in an inner region includes a membrane (4) on which at least one first measurement element (R1?) for detecting a pressure impingement of the membrane (4) is arranged. Additionally, at least one second measurement element (R3?) for detecting a pressure impingement of the membrane (4) is arranged on the membrane. The first measurement element (R1?) and the second measurement element (R3?) are arranged distanced differently far from the edge of the membrane. The output signals of the first and the second measurement element (R1?, R3?) are evaluated together in a manner such that the two measurement elements (R1?, R3?) detect a differential pressure acting on the membrane (4), and thereby compensate the influence of the system pressure acting on both sides of the membrane (4).Type: GrantFiled: March 17, 2009Date of Patent: November 2, 2010Assignee: Grundfos a/sInventors: Jens Peter Krog, Casper Pedersen, Carsten Christensen

Patent number: 7010984Abstract: The differential pressure sensor is formed of a semiconductor substrate (1) which is thinned out in an inner region into a membrane (2) which may be impinged by pressure on both sides. Measurement resistances (3a to 3d) for detecting the differential pressure (P1 minus P2) are formed within the membrane (2), and compensation resistances (4) are formed on the carrier, which are connected to measurement resistances (3). The measurement resistances (3) are connected into a first measurement bridge (6) and the compensation resistances (4a to 4d) into a second measurement bridge (7).Type: GrantFiled: July 2, 2004Date of Patent: March 14, 2006Assignee: Grundfos a/sInventors: Jens Peter Krog, Casper Pedersen, Carsten Christensen
