Connecting barrier gate control board with loop detector.
When people buy our barrier and loop detector, they will worried how to connection? OK,If you see diagram and video,It is very easy to know how to connection.

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...

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...

Loop detectors are used to detect the presence of vehicles

Loop detectors are used to detect the presence of vehicles. Typically the loop is connected to a loop detector. Some gate operators have built in sockets to accept loop detectors and some models require the detector to be wired in. Loop Detector Exit loops are used to open gates to allow a vehicle's exit. Safety loops are used to prevent a gate from closing on a vehicle. Two loops can be wired to one detector. This is frequently the case in safety loops. Loops are placed in front and behind the gate. Shadow Loops are typically used in commercial locations. A Shadow Loop keeps the gate open while a vehicle is above it, just like a safety loop, but only functions when the gate is in the full open position. Preformed Loops are placed below the surface prior to laying asphalt or pouring concrete. They are available in several sizes depending on driveway width. Car Loop Detectors  are used to detect the presence of a vehicle to open a gate, or as a safety device to prevent the gate...
