Nortech PD132 Enhanced Vehicle Loop Detector

Nortech PD132 Enhanced Vehicle Loop Detector UAE

Nortech PD132 Enhanced Vehicle Loop Detector is a professional single-channel inductive vehicle detector designed for automatic parking barriers, boom gates, sliding gates, industrial doors and vehicle access control systems. The detector identifies the presence of a vehicle by monitoring changes in the inductance of a loop installed beneath the road surface.

The Nortech PD132 provides advanced vehicle detection functions including Automatic Sensitivity Boost (ASB), selectable permanent presence, loop isolation protection, loop frequency indication, detect filtering and diagnostic capability when used with the compatible DU100 diagnostic unit. These features make it suitable for professional parking and gate automation installations where dependable vehicle detection is required.

Single Channel Vehicle Loop Detector

The Nortech PD132 is a single-channel detector designed to operate with one inductive loop installed in the roadway. When a vehicle enters the loop area, the metal mass of the vehicle changes the electrical characteristics of the loop. The PD132 detects this change and activates its output for connection to the parking barrier, gate controller or access control system.

This allows the detector to be used for vehicle presence, safety and automatic gate or barrier control depending on the installation configuration.

Automatic Sensitivity Boost – ASB

The Automatic Sensitivity Boost (ASB) function improves reliable detection of vehicles with a higher chassis, including trucks and truck-trailer combinations.

After a vehicle is detected, the detector can automatically increase sensitivity to help maintain reliable vehicle presence detection while the vehicle remains over the inductive loop.

Selectable Permanent Presence

The Nortech PD132 includes a selectable permanent presence function. When configured for permanent presence, the presence relay can remain active while a vehicle continues to occupy the loop.

This feature is particularly useful for parking barrier and automatic gate safety because it can help prevent the barrier arm or gate from closing prematurely while a vehicle remains in the detection area.

Loop Isolation Protection

The PD132 incorporates loop isolation protection. The isolation transformer provides additional protection against electrical transients and allows operation with suitable single-point-to-ground sensor-loop installations.

This feature is useful for professional outdoor parking and gate installations where loop wiring can be exposed to electrical disturbances.

Loop Frequency Selection

When two or more inductive loops are installed close together, interference or cross-talk can occur between detectors. The Nortech PD132 provides loop frequency indication and frequency adjustment to assist installers in identifying and reducing interference between adjacent loops.

Correct frequency selection is especially important in entrance and exit lanes where several vehicle loops may be installed close to each other.

Detect Filter Function

The Detect Filter provides a controlled detection delay that can help filter unwanted or short-duration inputs. This can be useful where the system should ignore certain small or rapidly moving objects while maintaining dependable vehicle detection.

DU100 Diagnostic Capability

The Nortech PD132 provides advanced diagnostic capability when used with the compatible Nortech DU100 handheld diagnostic unit.

This allows professional installers and technicians to obtain useful diagnostic information when commissioning or troubleshooting the vehicle detection system.

PD132 for Automatic Parking Barriers

The Nortech PD132 vehicle detector is widely suited to automatic parking barrier installations. Depending on the barrier controller and wiring configuration, the detector output can be used for vehicle presence, safety or automatic operation.

A common application is installing the inductive loop beneath the barrier lane so that the control system can determine when a vehicle is positioned within the protected area.

Prevent Premature Barrier Closing

One of the most important applications of an inductive loop detector is helping prevent an automatic barrier from closing while a vehicle remains beneath or close to the boom arm.

When the system is correctly designed and programmed, the PD132's permanent-presence capability can maintain the appropriate detector output while the vehicle remains over the loop.

PD132 for Automatic Sliding Gates

The Nortech PD132 can also be integrated with compatible automatic sliding gate motors. Depending on the gate controller, the relay output may be connected to an opening, safety or vehicle-detection input.

This makes the PD132 suitable for villas, residential communities, warehouses, factories, commercial properties and other controlled vehicle entrances.

Vehicle Access Control Integration

The PD132 can operate as part of a larger vehicle access control system. It can be combined with parking barriers, RFID systems, UHF long-range readers, card readers, remote controls and other compatible access-control equipment.

For example, an RFID or UHF system can authorize the vehicle while the inductive loop detector provides vehicle-presence information to the gate or barrier controller.

• Vehicle presence detection

How the Nortech PD132 Works

An insulated electrical cable is installed as an inductive loop beneath the road surface. The loop is connected to the PD132 detector through a twisted feeder cable.

When a vehicle enters the detection area, its metal body changes the inductance of the loop. The PD132 detects this change and switches its relay output. The connected parking barrier, automatic gate or access-control system can then respond according to its programmed logic.

Vehicle Loop Installation

Correct installation of the inductive loop is essential for reliable operation. The loop dimensions, number of turns, feeder cable, road construction, distance from surrounding metal and detector sensitivity should be selected according to the site conditions.

Where multiple loops are installed close together, frequency settings should be configured carefully to minimize cross-talk between detectors.

PD132 for Cars, Vans & Heavy Vehicles

The Automatic Sensitivity Boost function makes the Nortech PD132 particularly useful where different vehicle types use the same entrance. The detector can be used for passenger cars, vans and suitable heavy-vehicle applications when the loop is correctly designed and installed.

For truck and high-bed vehicle applications, correct loop geometry and sensitivity configuration are important for maintaining reliable detection.
