DIFFERENTIAL PRESSURE SENSOR ASSEMBLY
First Claim
Patent Images
1. A method of assembling a differential pressure sensor including a first pressure inlet and a second pressure inlet, the method comprising:
- providing a housing of the differential pressure sensor and a cover;
mounting the cover to the housing so as to form a pressure chamber, the differential pressure sensor being configured such that in operation, a pressure to be measured is transmitted into the pressure chamber;
heating a sleeve;
placing the heated sleeve around the cover and the housing; and
reducing an inner perimeter of the heated sleeve by allowing the sleeve to cool, wherein the sleeve is sized such that after cooling, the sleeve is configured to apply a force to the cover to press the cover against the housing of the differential pressure sensor.

Abstract
A method of manufacturing a differential pressure sensor is provided. The method includes providing a housing of a differential pressure sensor and a cover. The cover is mounted to the housing so as to form a pressure chamber. The differential pressure sensor is configured such that in operation, a pressure to be measured is transmitted into the pressure chamber. The method further includes heating a sleeve, placing the heated sleeve around the cover and the housing and allowing the sleeve to cool.

9. A differential pressure sensor assembly for measuring differential pressure between a first pressure inlet and a second pressure inlet, comprising:
-
a housing of a differential pressure sensor, a cover mounted to the housing, a pressure chamber being formed by the cover and the housing, the pressure chamber being adapted to receive, in operation, pressure to be measured; a sleeve, disposed around the cover and the housing, wherein the sleeve is sized apply a force to the cover which presses the cover against the housing of the differential pressure sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 22, 23, 24)
