Charge output accelerometer

Main charge output piezoelectric acceleration sensor acceleration sensor zirconate titanate ceramics, has a wide operating temperature range, wide dynamic range, wide frequency range ( usable frequency > 10kHz). Charge output of the piezoelectric type acceleration sensor is encapsulated in an airtight ceramic metal housing . Due to the ability to resist harsh environments , which has a very good durability. Because of its high impedance, Camshaft Sensor requires a charge amplifier and low noise with shielded cable is used , preferably a coaxial cable. Low noise cable is a finger which has a low friction electrical noise, which is generated by the movement of the noise from the cable itself . Many sensor manufacturers also offer this low-noise cable. Charge amplifier and charge output type acceleration sensor connection, which can eliminate the cable capacitance and the impact of Position Sensor capacitor in parallel . With advanced charge amplifier , charge output type acceleration sensor is easy to achieve wide dynamic response (> 120dB). Since the piezoelectric ceramic is very wide temperature range , some sensors may be used to -200 ° C to +400 ° C, or even wider temperature environment. They are particularly suitable for vibration testing under extreme temperatures , such as turbine engine monitoring .
