Triaxial piezoelectric accelerometer with integrated electronics DJB INSTRUMENTS
Lightweight triaxial vibration transducer comprising three KONIC all welded inserts, each with hybrid QVC, bonded orthogonally into a hard anodised aluminium housing. The inserts are electrically insulated, individually
and from the housing, thus eliminating ground loop interference. Low impedance O/P provides a high degree of noise immunity (80dB
improvement vs. equiv. charge source device @ 50Hz) and allows use with low cost coaxialcable.
The additional mechanical isolation implicit in the construction provides also near elimination of strain induced error. All the 3x10/32 Microdot connectors are exiting in the same direction.
The spatial response of a structure to dynamic forcing, may lead to erroneous single axis vibration or shock measurement due to the
inherent directional property of the transducer.
