AT/04 Piezoelectric triaxial accelerometer-1

AT/04 Tri-axial Piezo Electric Accelerometer Sens 3/6 pC/g A lightweight triaxial vibration transducer comprising of three charge output piezo-electric accelerometers mounted orthogonally within a titanium block and welded construction. The AT/04 is based upon the A/24 single axis voltage accelerometer and maybe considered as an alternative to the A/31 or A/34. However, the latter by virtue of being a grouping of single axis devices, are repairable and in addition the physical separation of the cable leads to visible signal axis traceability. Sensitivity Deviation (%). With a 4 pin connector available with standard or ruggedized single cables with three BNC labelled breakout leads the AT/04 is well suited to Automotive/Aerospace applications.
