PD 130 Single Channel Detectors


The innovative PD130 series of single channel inductive loop vehicle detectors are used to detect the presence of vehicles by means of an inductive loop buried under the road and have all the features and benefits found on much larger modules. No longer is it necessary to make compromises when selecting a detector for parking control and motorised door or gate applications - these "one chip" microprocessor-based units are suitable for them all. Available in over 100 variations these detectors can cater to your every system requirement.

 APPLICATIONS

 

· Parking barrier control
· Vehicle counting
· Motorised gates and doors
· Industrial control systems
 

 FEATURES

 

 


· Compact Size:

 


This compact and well engineered housing combines all of the industry requirements regarding features and functionality and allows this detector to be incorporated into any new or existing vehicle detection system.

· Diagnostic Capabilities:

 

Comprehensive diagnostics capabilities allow for accurate diagnosis of loop and installation problems.
· Selectable Permanent   Presence:
The output of the presence relay can be selected to maintain an output for an indefinite period, eliminating premature barrier / gate / door closure.
· Loop Isolation Protection:
The loop is isolated and provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops. Added filtering reduces interference from external noise.
· Loop Frequency Indication:
Interference between adjacent loops / detectors can be determined by an integral indication, and eliminated by changing the frequency settings.
· Environmental Analyser:
Continuous monitoring of external parameters ensures reliable product performance and operations under all environmental and power supply conditions.
· Automatic Sensitivity Boost   (ASB)
Facilitates the reliable detection of all vehicle combinations and high-bed vehicles by boosting the sensitivity to maximum after detection of a vehicle.
· Detect Filter:

Provides a turn-on delay, thus allowing selective detection which is often useful for screening out unwanted inputs.
· Powerfail Memory (options)
In the event of a power failure, the PD130 detector will retain the presence of the vehicle when power is restored. This is most useful in applications where damage to vehicles could occur ( e.g. Rising Bollards)
