What Is a 200EP Inductive Amplifier?

By Matt McGew

Manufactured by specialist tool company Tempo, the 200EP inductive amplifier is used primarily by electricians, construction workers and telecommunications engineers to detect hidden wires. The unique quality of this amplifier, and other amplifiers within the same category, is that the 200EP does not require actual physical contact with an electrical object, such as a wire under voltage.

Using the 200EP

One of the primary uses for the 200EP inductive amplifier is to locate wires hidden underground and any breaks or disruptions in these wires. Wires are often buried beneath concrete and other fixed materials, making easy detection without direct contact a necessity. The 200EP inductive amplifier can also work in tandem with tone generators to locate cables such as telephone cross connections.

Wire Types

The 200EP inductive amplifier can detect AC wires, alternating current wires that have electric currents running through them. The current in AC wires changes direction occasionally and spontaneously. The opposite of an AC wire is a DC wire; the current in DC wires flows in only one direction. AC wires are more widely used than DC wires and provide electricity for both residential and commercial premises. The 200EP inductive amplifier detects both AC and DC wires.

Product Features

The 200EP inductive amplifier supports accurate readings with tight groupings of multiple cables and maintains the ability to correctly identify cables. The 200EP also allows you to change the volume of the identifier. This is a useful feature in cases where the tone may interfere with the correct identification of a wire.

Extra Features

The 200EP comes with an extra LED that makes it easier to read the indicator for signal strength. The tool itself is battery-operated, but the batteries are not included with the purchase. The 200EP inductive amplifier does, however, come with a two-inch speaker, a metal tip and an extra duckbill.
