Working principle of Loop detector
inductive loop detector monitors the change in the inductance of the conductor cycle, which is laid on the ground. When metal mass cycle arrives on the detector sends the relay signal to the door control panel as the vehicle presence.
The system does not produce images and is not designed to detect pedestrian. This feature can reduce unnecessary pedestrian triggers in the desired factory and warehouse doors, opening with only vehicle passage.
Loop cable and floor layout
The size of the cycle is determined according to the geometry of the approach with the number of tours and the type of vehicle to the door. The cable channel should be properly cut, avoid sharp corners and the filler material should be suitable for the working condition of the floor.
The reinforcement can affect the signal of movable metal caps, heating lines and neighboring loops. Before assembly, the floor structure should be examined; the cable student should be protected against the continuous mechanical load of the vehicle wheel.
Sensitivity and waiting adjustment
The sensitivity can not be detected if very low, small tools can be detected; if very high, environmental metal changes can be miscompressive. Frequency and sensitivity adjustment should be tried with different tools on site.
Asset time adjustment is important in the loading scenarios where the vehicle can stand under the door. Is the door being opened only when approaching, it is defined in the control logic, which should remain open until the vehicle space leaves.
inductive loop detector Is radar?
inductive loop detector metal tool is strong in choosing and does not be affected by the viewing line but requires floor cutting. The radar is mounted without interfering to the ground and can detect the direction of approach, but it can be affected by pedestrian or neighboring movements.
Two systems are used together in some projects: radar early opening, loops are corrected to the presence of vehicles. The most convenient solution is determined according to the requirement of traffic type, ground condition, speed and access control.
Failure diagnosis and maintenance
If the detector is constantly full when the vehicle is destroyed, the leakage on loop cable can be found, the connection problem, frequency conflict or close metal movement. If the vehicle is not detected, the kopuk operating cycle, low precision or incorrect settlement is controlled.
Electrical measurement and channel repair should be performed by competent personnel. After commissioning, the detection limit with different vehicles, the door opening time and safety behaviour are confirmed together.
Inserting vehicle detection zone into field
The loop area can be detected quickly if the door is very close to the door; if the door vehicle is far away, the road can be turned on unnecessary. The distance is determined according to the safe time calculated from the actual approach speed of the vehicle with the opening time of the door.
The development and asset loops in two-way corridors can be undertaken separately. The control system prevents the second area from closing until the vehicle has been completed while opening the door with the first signal. So it does not stay connected to a single timer.
Ground movement can affect the life of the joints, equipment and water inlet cable. The channel geometry and filler material is based on vehicle load; the connection cable should be separated in accordance with power lines and interference sources.
In the circuit, the metal masses used really on the field like motorcycle, forklift, transpalet and truck should be tried separately. The untargeted vehicle requires re-extinguish frequency adjustment with hassasiyet or small vehicle’s missed precision.

Final assessment and technical quotation
The right decision for inductive loop detector is based on evaluating measurable site data together, rather than focusing on a single catalogue value. Options can be compared technically when the clear opening, peak-hour traffic, environmental conditions, safety functions and automation requirements are recorded in the same project brief.
This guide provides a preliminary assessment. The final product, capacity and accessory selection should be confirmed after a site survey and risk assessment. A quotation that clearly defines the door assembly, drive, sensors, safety equipment, supporting structure, installation, commissioning and maintenance scope enables a more reliable comparison of total cost of ownership.
Frequently Asked Questions
inductive loop detector What does it work?
Embedded in the floor operating cycle detects metal vehicle presence and gives automatic door trigger signal.
inductive loop detector Do they perceive the pedestrian?
No; the basic working principle is inductive of metal mass operating cycle is the effect on it.
inductive loop detector Will the floor be cut in the installation?
The controlled channel for cable loop in most applications opens; surface type solutions available according to project condition can also be evaluated.
