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...

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...

Safety Photocells Infrared Photocell for Automatic Gates / Barrier Gate

Safety Photocells for Automatic Gates / Barrier Gate Photocells or Photo Electric Beams are basically a point to point beam of invisible infra red light that passes from a transmitting unit to a receiving unit and if an object blocks the light you know something's there. These are used with automatic gates on either side of a driveway as a safety device to prevent a gate closing on a vehicle. Normally used when a gate is set to close by itself after a time delay automatically (auto-close). Infrared Photocell Sensor Alignment The most important thing when installing Photocells is to make sure they are facing each other.   The beam of light coming from the transmitter is quite narrow so if not aimed at the receiver properly it may not work or worse still only just works and then as soon as there is some rain will stop working leaving the gate open. Height of the Photocell photocells at different height to cover all vehiclesThe height of the Photocell is impor...
