A sensor device including a mechanical oscillator, an excitation unit which is configured to excite the mechanical oscillator to perform a mechanical oscillation within a non-linear range at a varying excitation frequency, and an evaluation unit configured to detect a jump, arising as a result of anharmonicity, in a resonance oscillation of the mechanical oscillation of the mechanical oscillator.

Sensor device and method

An apparatus including a chamber having a chamber opening, a plunger which is movable within the chamber so as to change a chamber volume, which is defined by the plunger and a chamber wall and which adjoins the chamber opening, includes a measurer for measuring a pressure within the chamber or for measuring a force F, F being the force which acts upon the plunger so as to change the chamber volume.

Apparatus and method for controlling and monitoring the pressure in pressure line or pipes
