Abstract
A relative-pressure sensor is provided which is protected against contaminants and/or moisture and manages without an oil filling, having a gas-filled measuring chamber ( ), which is sealed with a pressure-sensitive measuring diaphragm ( ), on the outside of which a pressure (P) to be measured acts during operation, a gas-filled compressible resilient bellows ( ), on which a reference pressure (R) acts from outside during operation, whose internal volume depends on the reference pressure (R), and which is connected to the measuring chamber ( ) in order to adapt an internal pressure prevailing in the measuring chamber ( ) to the reference pressure (R), and a transducer for converting a pressure-dependent deflection of the measuring diaphragm, ( ) into an electric measured variable.
