  • Patent number: 7152477
    Abstract: A pressure sensor having a measuring cell (1) and sensor electronics (13) connected with the measuring cell (1), wherein the sensor electronics (13) and its electrical connections are protected from external influences, wherein on front side of the measuring cell (1) a pressure sensitive element is arranged, on which a pressure (p) acts during operation, and wherein the sensor electronics is arranged on a rear side of the measuring cell (1). The sensor has connected with the measuring cell (1) a cap (19, 27), which encloses the sensor electronics (13), and at least one bushing (25), through which the connection lines (17) connected to the sensor electronics (13) pass.

  • Patent number: 5535629
    Abstract: A transducer assembly for measuring pressure or differential pressure includes an oxide ceramic pressure measurement cell removably retained inside a connection housing by an annular set ring on a first side and by a cup packing located on a second side. The pressure measurement cell is held at a fixed distance inside a connection housing from a connector element. The connection housing removably connects to a main housing, allowing for release and replacement of any of the elements within the assembly, thus enabling adaptation of the device to different applications without recalibration.
