A presentable voltage sensor includes an electrode faced by an electric field probe and connected to a voltage source; a screening conductive shell wrapping the probe and connected to a reference potential; a dielectric material housed within the shell and interposed between the probe and the electrode; a conditioning circuit connected to an exit of the sensor and having a resistor of resistance Rinterposed between the probe and a second reference potential; and an integrator circuit formed from an RC network and having a resistor of resistance R, a capacitor of capacitance C, and a loss factor which, at a frequency of interest, is of an order of 10.

Presettable transducer for electrical quantities

A capacitive sensor for detecting an electrical field generated by a live conductor comprises a source electrode (), a screen element () and an electrical field sensor (). Said source electrode () has a proximal portion () connected to the conductor (A) and a distal portion () placed inside the screen element (). The electrical field sensor () is placed inside said screen element (), and faces and is spaced apart from the distal portion () of said source electrode (), in order to detect the electrical field emitted by said source electrode ().

Capacitive sensor to sense an electric field generated by a conductor

An apparatus for sensing impact of a body on a strip located on a support, characterized by comprising: a strip () of material presenting piezoelectric characteristics, applicable to a support in the region to be monitored; at least one continuous tape () made of conductive material and associated with said strip () in a manner parallel to it; a device () connected to said tape to condition the electric signal generated by the impact of said body on said strip (); a device () for sensing said signal; a device () for indicating the sensed signal.
