Vehicle Loop Detectors, Loops, and Loop Accessories for Gate Operators & Other Equipment Free Exit or Entrance for Automated Gates and Doors:  Loop detectors and loops may be used for a variety of applications. Vehicle loop detectors are frequently used to provide free entrance and/or free exit for traffic. Wire loop detector directly to  gate operator  or overhead door, connect to buried loop, and allow larger metal objects which drive over loop to trigger the gate or door to open, or close. Loops remain practically invisible, buried beneath gravel, asphalt, or concrete driveways. Vehicle loop detectors are a safe and reliable way of controlling an assortment of equipment. Safety Devices for Automated Gates and Doors:  Vehicle loops and loop detectors are also frequently used as safety devices. Loop detectors are wired or plugged directly to the gate operator or overhead door. Loops are buried directly under the automated gate or door. When a vehicle, or oth...

What is a LOOP? Loop Installation?

What is a LOOP? A loop sensor is a detector that senses a change in inductance caused by the passage of a vehicle near the sensor. It is used to manage traffic flow. Vehicles passing over or stopped within the detection area of an inductive-loop detector decrease the inductance of the loop. The electronics unit senses this event as a decrease in frequency and sends a pulse to the controller signifying the passage or presence of a vehicle. Loop Installation? Traffic Counting Loops are installed in the surface asphalt of secondary roads, highways, freeways & freeway ramps. The number of loops per location varies from 1 (on a single lane ramp) up to 8, 10 or more on a multi-lane freeway. The dimensions of a loop are dependant on the exact requirements from Ministry of Transportation, Ontario, Region or Municipality requesting the work. In order to install the loops Highway Technology requests permission to close the lane or lanes in which the work is to t...

Inductive Loop Detector works by detecting an inductance change in wire loop (coil) that is buried in road

 Inductive Loop Detector works by detecting an inductance change in wire loop (coil) that is buried in road. It does that by measuring the frequency of the internal oscillator which powers the mentioned coil. When a metallic object moves over the coil it changes its inductance and that in turn changes the oscillator frequency which is measured by the microcontroller. It is used for vehicle access control at door and barrier controls, for monitoring the occupancy and for vehicle counting in parking garages, for traffic light installations and traffic...
