Paired with a <a href=\"https:\/\/sunfre.com\/product-category\/high-speed-barrier-gate\/\">barrier gate<\/a>, it automates arrival detection and prevents the boom from closing on a vehicle.<\/p>\n<h2>How a loop detector works<\/h2>\n<p>The loop is cut into the pavement and tuned to the detector card. When a vehicle enters, inductance drops and the detector sends a relay signal to the barrier controller. Two common configurations are a <a href=\"https:\/\/sunfre.com\/product-category\/single-loop-detector\/\">single loop<\/a> (presence only) and a <a href=\"https:\/\/sunfre.com\/product-category\/double-loop-detector\/\">double loop<\/a> (presence plus direction).<\/p>\n<h2>Why integrate loops with barriers<\/h2>\n<ul>\n<li><strong>Safety:<\/strong> the boom will not lower while a car occupies the exit loop.<\/li>\n<li><strong>Automation:<\/strong> the gate opens on arrival without a manual button.<\/li>\n<li><strong>Counting:<\/strong> double loops can count entries and exits for occupancy data.<\/li>\n<\/ul>\n<h2>Installation notes<\/h2>\n<p>Loops are placed just before and just after the boom. Saw-cut loops must be sealed properly and kept clear of rebar where possible. For sites where cutting pavement is impossible, wireless or radar presence sensors are an alternative.<\/p>\n<p>For a full selection framework, see our <a href=\"https:\/\/sunfre.com\/barrier-gates-guide\/\">barrier gate guide<\/a> and the <a href=\"https:\/\/sunfre.com\/access-control-applications\/\">applications overview<\/a>.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>What does a vehicle loop detector do?<\/h3>\n<p>It senses a vehicle by a change in inductance as metal passes over a buried wire loop, then signals the barrier controller.<\/p>\n<h3>Why use a double loop instead of a single loop?<\/h3>\n<p>A double loop adds direction sensing and vehicle counting, while a single loop only confirms presence in one spot.<\/p>\n<h3>Can I install a loop where I cannot cut the road?<\/h3>\n<p>Yes. Where saw-cutting is impossible, wireless or radar presence sensors can replace inductive loops.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A vehicle loop detector is a buried wire loop that senses a car by the change in inductance as metal passes over it.
