Frequently asked questions:

What is a non-contact voltage tester used for?
Voltage testers or detectors are used to check the flow of current through a circuit. They can be used to check safety, or to ensure equipment is functioning correctly. They can also test for the current strength, whether the circuit is grounded correctly or to ensure no current is flowing at all so that work can be begin on the circuit.

How do non-contact voltage testers work?
Also known as a voltage detector, voltage tester pens, sensors or test pens. They allow the user to test electrical conductors without touching them. Non-contact testers are the safest and easiest way to detect electric fields or voltage. Voltage testers utilise what is called capacitive coupling, the user holding the instrument provides a ground reference. The tester then detects changing electric field around the object or objects conducting an AC current. (Alternating current) Simply put, the user and the tester pen when near the electrical conductor will cause a small current to flow through the tester from the source, this is how it detects AC voltage.

How do magnetic field sensors and detectors work?

Magnetic field sensors are able to detect changes such as direction, strength or flux in a magnetic field. Magnetic field detectors are able to detect fields, such as unipolar, bipolar and electro-magnetic. There are many types of technology used for this and they all have different approaches. Some record the resistance, some have coils surrounding magnetic material, another measures fields against an internal magnet based response that runs through a fluxing set of parameters. Some devices contain switches, when the state of the switch is changed for example from open to closed, a magnetic field has been detected. The most commonly known technologies are Fluxgate, Hall Effect, Magnetoresistive, magnetoinductive and SQUID. (Superconducting quantum interference devices)
