Description

Loop detectors in recent years have become a popular tool having innumerable applications in policing, right

from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the

loop detector.

The digital technology of the loop detector enables the equipment to sense a change in the inductance of the

loop as soon as it detects the metal object in its path. The inductive loop which detects the object is made of

insulated electrical wire (32/020; 32 Strand, 2mm diameter) and is arranged either as a square or rectangle shape.

The loop consists of several loops of wire and consideration should be giving to the loop sensitivity when

installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum

detection (8 levels via a dip switch settings). Channel 1, is set by the 10 way dip switch and channel 2 is set by 7

way dip switch. When detection occurs, the detector energises 2 relays for the output (each can be configured

individually). This energising of the relay can be configured into different modes, by selecting the respective dip

switch.
