Dynamische piezoelektrische Druckaufnehmer

Piezoelectric Pressure Sensors, sometimes referred to as pressure microphones are primarily designed for measuring pressure transients, dynamic pressure pulsations in liquids or gases, dynamic blasts and rapid pressure variation & surges.This type of pressure sensor allow for high accuracy, highly stable measurements in harsh environments, and can also be used to indirectly measure other variables such as fluid/gas flow, speed and water level.

Dynamic pressure transducers based upon piezoceramics allow deflection of acoustic type phenomena including turbulence and cavitation associated with fluid flow and are produced in two basic packages.
For applications involving significant background vibration, accelerometer compensation may be included.
The high sensitivity and linearity of these devices allow detection of accoustic levels as low as 70dBA superimposed upon pressure fields up to 500bar.
DJB’s range of dynamic pressure transducers offer solutions for high temperature applications as well as vibration compensated options, full signal conditioning equipment is also available.
