induksjonsløkkesensor

An induksjonsløkkesensor, also known as an induction loop detector or just a loop detector, is an electromagnetic sensor used to detect vehicles. It works by creating a loop of wire buried in the pavement, which generates a magnetic field when an electric current flows through it. When a metal object, such as a vehicle, passes over the loop, it disrupts the magnetic field, causing a change in inductance. This change is then detected by a control unit, which can trigger an action, such as activating a traffic signal or opening a gate.

These sensors are commonly found at traffic intersections, railway crossings, and automated gates. They are particularly useful for traffic management systems as they can provide real-time data on vehicle presence and flow. The sensitivity of the loop can be adjusted to detect different types of vehicles. The size and shape of the loop are also important factors in its performance. Larger loops are generally more sensitive and can detect a wider range of vehicles, while smaller loops are better suited for detecting smaller objects or for use in specific applications. The installation of induction loops requires careful planning and execution to ensure proper functionality and longevity.
