Definitions
- the pressure sensor is a differential pressure measuring cell
- the housing has two side flanges, between which the pressure sensor is clamped, and surfaces of the side flanges which come into contact with the medium at the measuring location are provided with a coating of enamel or of a glass-like material.
- FIG 3 shows a section through a pressure measuring unit according to the invention with a differential pressure sensor enclosed between two side flanges.
- the housing 1 is e.g. made of a very inexpensive steel or stainless steel compared to special materials.
- the ceramic pressure sensor 1 is in the illustrated embodiment an absolute pressure measuring cell consisting of a base body 3 and one on the Base body 3 arranged pressure-sensitive membrane 5.
- the base body 3 is made of ceramic, such as aluminum oxide (Al 2 O 3 ).
- the membrane 5 can also consist of ceramic or be made of glass or sapphire, for example.
- the membrane 5 and the base body 3 are connected at their edge to form a measuring chamber 7 by means of a joint 9 in a pressure-tight and gas-tight manner.
- the membrane 5 is sensitive to pressure, ie a pressure p acting on it causes the membrane 5 to deflect from its rest position.
