Abstract

Amplifying apparatus sensitive to the conductivity of a medium usable in assemblies of electrical installations, characterized in that it comprises a rectifier, an amplifier circuit and a probe whose terminals, when they are connected through a medium endowed with still little conductivity, cause the activation of the amplifier circuit, allowing the power supply of a consumer device either directly or by means of a suitable relay. The elements that make up the circuit are enclosed inside a small housing and closed by a cover fixed by a flange which in turn is provided with means for fixing the device on a support, in combination with other installation devices electric (Machine-translation by Google Translate, not legally binding)
