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.
