LD100 Loop Detector


The LD100 is a single channel inductive loop detector designed for parking and access control applications.
The detector is connected to an inductive loop mounted in the road surface. When vehicles pass over the loop the detector switches on an output.
The use of microprocessor and surface mount technology enables a large number of functions to be incorporated into a small package. The LD100 is compatible with most single channel detectors on the market and is easy to set-up and install. 

Reset Switch. Pressing the reset switch enables the detector to be manually reset during commissioning and testing. This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection.
Switch selectable Sensitivity. The detect sensitivity is the minimum change in inductance required to produce a detect output. (%∆L/L). Eight sensitivity settings are available on the switches to allow flexibility in configuration.
Sensitivity Boost. This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles.
Filter Option. This option is used to provide a delay of 2 Seconds between detection of the vehicle and switching of the output relay. This delay is normally used to prevent false detection of small or fast moving objects.
Extend Option. When switched on this feature extends the presence output relay for 2 Seconds after the vehicle has left the loop.
Permanent Presence. This feature ensures detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods.
Pulse Relay Selection. The Pulse relay may be configured to energise on detection of a vehicle or to energise when the vehicle leaves the loop.
Selectable Pulse Time. This feature sets the length of time that the pulse relay will be energised. 1 Second or 0.2 Second.
