Abstract
A sensor apparatus and method are disclosed herein, including a sensor element located on a base and a cover located proximate to the base. The cover generally includes a sensor diaphragm and a dimple that can form a part of the cover. A flanged area or flanged portion can also be connected to the bottom portion of the cover. The flanged area provides a surface for contacting a fixture to which the sensor apparatus attaches and holding the sensor apparatus to the fixture in a manner which prevents the sensor diaphragm from contacting the fixture and inducing errors during sensor operations thereof. The cover also can include a flanged or brim-shaped portion which is connected to and surrounds the bottom portion of the cover. The flanged portion can be positioned parallel to the sensor diaphragm.
