loop detector

The LD-200 Enhanced single channel detectors can be used in a variety of applications in the parking and door / gate environments:
1. To arm card readers and ticket dispensers.
2. As a barrier/gate/door closing detector.
3. As a barrier/gate/door opening detector (Free exit).
4. To generate pulses for counting vehicles. 

Direction Detection:

If vehicle moves from CH1 to CH2, and left CH1, then CH1 relay pulse output; if vehicle moves from CH2 to CH1, and left CH2, then CH2 relay pulse output

Description:

The loop consists of several loops of wire and consideration

should be giving to the loop sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum detection (16 levels via a trimpot). When detection occurs, the detector energises 2 relays for the output (each can be configured individually). This energising of the relay can be configured into different modes, by selecting the respective dip switch.

Sensitivity Selection
       Sensitivity of the loop can be adjusted by the trimpot labeled “Sensitivity”. User can select 16 different setting by turning the trimpot with 0 being the least sensitive and “F” being the most sensitive.

Loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control. Automation of gates and doors has become a popular usage of the loop detector.

The NBT-ILD™ vehicle loop detector is compatible with most gate operators. The ULT-MVP may be used in Center, Safety and Exit loop positions.Fifteen sensitivity settings allow for fine adjustment of the detection level.
