Previous Manuals & Datasheets. humidity, temperature) • Very easy to control small (sub-micron) displacements with applied voltages. Piezoelectric force sensors are low impedance voltage force sensors designed for generating analog voltage signals when a force is applied on the piezoelectric crystal and are widely used in machines for measuring force. C1 is equal to the parallel plate capacitance found on the sensor's datasheet and will vary from sensor to sensor. Typical sensors of this type are a knocking sensor of an automobile engine and a shock sensor. Reaction torque sensors (piezoelectric) A torque acting on the sensor produces tangential shear stresses in the quartz disks. The Piezoelectric sensor is a sensor used to measure the change in the pressure, force, temperature and acceleration. We’ve discussed the piezoelectric phenomenon in the context of electronic sensor devices, and we saw that a piezoelectric device can be represented by a current source in parallel with a capacitor or by a current source in parallel with a capacitor and a resistor. The general benefits of the piezoelectric accelerometer are it has a wide frequency range, the output noise is very low, there is no external power supply is required & it has self-power generating. 5 de Outubro, n. 70 – 8.
