industries, an inductive amplifier is a type of test instrument that does not require
DC electrical contact to detect an
AC wire under voltage.
The conventional use of the inductive amplifier is the location of breaks in hidden wires, even buried in concrete. The typical wire detection range in a concrete wall is 10–20 cm.
Inductive amplifiers can also be used to find an individual cable pair in a telephone cross connect or cable head when used in conjunction with a
tone generator
A signal generator is one of a class of Electronics, electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typ ...
