Measurement device for acquisition of vibration signals, especially pressure pulses in a fluid

摘要

Measurement device for measurement of vibrations, especially pressure pulsations in a liquid, comprises a housing (1) with a membrane type wall surface (4) and a sealed-off, gas-filled, inner space (5) inside the housing for containment of a signal transducer. The signal transducer is a microphone capsule (6) suitable for detection of sounds in the human voice range.
