In this study, the local PZT-PVDF composite sensors are produced. The
PLC based hydraulic pressure system (250kgF) is as specially designed and
fabricated to produce these sensors. The composite sensors are threated under
pooling condition in silicon oil at 30 minutes, 120^oC.  Frequency-voltage charactrestics of the piezoelectric
sensor that integrated on vibration measurement system are defined, in addition
d₃₃ (piezoelectric coefficient), capacitance (C), and Q_m
(mechanical quality factor) values are determined. It is seen that, fabricated
these sensors have 2.5 to 3.7 V_pp (pick to pick) voltage at 10Hz
resonance frequency. d₃₃ and Q_m values of the mentioned
sensors are characterized as 10.5-8.6 , 3.7-2.5, respectively. In lower
frequency, these sensors which have maximum 3.7 V_pp voltage may use
as strain sensor, vibration sensor, atomic force microscope cantilever
piezoelectric sensor, etc. For the first time, the local piezoelectric sensors
are fabricated, and PLC based hydraulic pressure system is designed to produce
them in Turkey.
