A pressure measuring device comprises a capacitive pressure measuring cell, a process connector including a retaining element, a housing mounted on the process connector, and a sealing element arranged between an inwardly projecting region of the retaining element and the pressure measuring cell. The retaining element is configured with a cap with a base area portion and an outer area portion bent over with respect thereto and fitted over an end face of the process connector. The retaining element is in a material-bonded and/or form-fit manner connected to the process connector exclusively in the bent-over outer area portion so that the base area portion assumes a resilient property.

Pressure measuring device

A process for detecting the operating state of a pump of a pump system, involves the steps of: detecting at least one pressure and/or flow profile P(t) in the pump system, computing of at least one characteristic value Kfrom the pressure and/or flow profile P(t), comparing the computed characteristic value Kwith at least one defined characteristic value Kor with a range bordered by the characteristic value K, the defined characteristic value Kor the characteristic value range corresponding to the operating state of the pump of interest, and outputting the operating state determined by the comparison. With the process, the operating states of pumps, pump systems and hydraulic systems is determined by the computed characteristic value Kcharacterizing the pulsation of the pressure and/or flow profile P(t) in a computation time interval &#x394;t, the pulsation quotient being computed as the computed characteristic value K.

Process, sensor and diagnosis device for pump diagnosis

A measurement apparatus for determining the position of an object relative to a reference surface, with a measurement nozzle, a reference nozzle, and a measurement device, the outlet opening of the measurement nozzle being located in the reference surface. A compressed air source provides air having a certain feed pressure so that the measurement device acquires one of three state variables: flow rate, pressure and speed of the air upstream of the measurement nozzle.
