The Loop Replacement System (LRS) features advanced 3-axis, magnetoresistive sensing technology that responds to changes in the Earth’s magnetic field caused by ferrous objects. Three sensing elements provide measurements in the X, Y, and Z axes to improve detection sensitivity when used in either above or below ground installations.

The LRS is equipped with our new DETECT-ON-STOP™ or (DOS®) feature, which allows detection only when a vehicle has come to a complete stop. This EMX exclusive feature is a major advantage if you want to ignore cross traffic in tight spaces.

The small size of the LRS allows for easy installation in pavement (below grade) with a single saw cut. It provides cost savings on labor and materials when compared to the multiple cuts and corner reliefs required for the installation of inductive loops. The rugged sensor is also suitable for above-grade installations, making it ideal for use in confined areas or hidden in non-ferrous architectural components for security purposes.
