The DJB piezo-electric dynamic pressure
transducers
-
DJB piezo-electric dynamic pressure transducers allow
detection of acoustic type phenomena, turbulence, cavitations, associated with fluid flow,
air blast and combustion gas measurement. Signals may be superimposed upon high static
pressure backgrounds
-
For applications involving significant background vibration,
accelerometer compensation may be included.
-
Very high temperature transducers, up to 600 °C, are
available.
