Piezo-Electric Accelerometers - A/123/E - 1

^)DJB Instruments 123/E/ SI TE/ TS Piezo-tronic Voltage Accelerometer accelerometers includes a hybrid QVC, packaged to offer choice of side/top entry connector, integral stud or flat base (for adhesive mounting). Applications including modal analysis of lightweight structures and shock measurements are subject to individual phase/gain errors associated with the lower corner frequency of the QVC's. The radiometric nature of the modal analysis however reduces transfer function uncertainty to the associated lower corner frequency variations of individual QVC's. Thus a +1-5% corner frequency tolerance associated a +/- 1/2 degree phase tolerance at the nominal corner frequency. Peak shock of up to 600g with certain provisos relating to bandwidth response characterized by a single low frequency pole air, giving rise time. Droop will be 10% of peak pulses, for QVC corner frequency = 0.7Hz. Overshoot caused by ringing will be 10% for rise time 30u.Sec. and if excessive may lead to signal NOTE: Voltage sensitivities shown are standard.
