LD-200 is a 2 channel 16 bit Digital Signal Processor (DSP) based 
Inductive vehicle Detector.

The primary function of the Detector is to detect vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface.
The switches allow for different loop frequency settings, sensitivity settings, direction logic settings, pulse logic setting and presence logic settings.

Characteristics

• Switches on front panel for selecting various modes.
• Self calibration after switch change.
• Leds on front panel indicating the detectors current operating status and condition.
• To minimize crosstalk between channels, the detector scans the channels sequentially.
• Output signal as "Pulse" or "Presence" for each channel. Output signal is active on detect, leave or delayed.
• Option for direction recognition by using two channels.

Usages

• Traffic detector.
• Commercial, industrial doors and gates.
• Car parks – counting and occupancy.
• Parking bollards.

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...

Barrier Gate Working With Jutai Products Gate barriers are typically found at level crossings, parking facilities, checkpoints and entrances to restricted areas. They are also the usual method for controlling passage through toll booths, and can also be found on some freeway. entrance ramps which are automatically controlled to drop to restrict traffic in the event of accident cleanup or road closures without the need to dispatch road workers or law enforcement to use a vehicle to block the way. Some barrier gates are automatic and powered, others are manually operated. In some places, boom gates are installed across suburban streets as a traffic calming measure, preventing through traffic, while allowing to take advantage of the shorter and more direct route authorized vehicles such as emergency services and buses. barrier gate installed in Taiwan Automatic boom barrier gate can be operated through Jutai Products 1.
