ABSTRACT:
A pressure transducer, having a measuring element contained in a housing, is acted upon by the pressure to be measured and, due to its elastic properties, also acts as the measuring spring. A measuring transducer presenting no problems as to overload protection, having only small error, and useful with almost any pickup, includes a pressure sensing element consisting of two disc-shaped parts which are tightly joined together, facing each other, so as to form an inside cavity. One of the disc-shaped parts has a central cutout and is connected at the cutout to the housing. An opening in the housing in the vicinity of the central opening leads into the inside cavity. A transmission element is attached centrally to the other disc-shaped parts. The invention can be used in pressure and pressure difference transducers.
