Piezoelectric Ceramic Sensors (PIEZOTITEr)
Electric Potential Sensors
Every object has its own surface electrical charges or
charges given to it from other objects. These
electrical charges cause the object to have a certain
electric potential with respect to other objects. The
electric potential sensor is designed to measure this
surface potential.
There are two major surface potential detection
methods : The field-mill method and the vibrating
capacitance method.
The former method synchronously shuts off the
electrical flux from the object surface and modulates
the electric field incident to the sensing electrode
to induce an AC current on the electrode, proportional
to the surface potential (DC). The latter method forms
a capacitance across the surface of the object and the
sensing electrode, and vibrates the sensing electrode
vertically the surface of object to induce electrical
charges which are proportional to the capacitance and
surface potential, thereby obtaining an AC current
proportional to the surface potential (DC).
Murata's potential sensors, use a high-precision,
piezoelectric tuning fork ("MICROFORK") with a proven
production record, to achieve field shut-off vibration
and electrode vibration. Integrating all of the signal
processing circuit, Murata's electric potential sensor
assures high operating stability and reliability.
