Products---single channel vehicle detector
Traffic vehicle detector
name:traffic control inductive loop detector presence signal pulse signal ce/fcc
Parking traffic vehicle sensor Features:The PD-155 loop detector is an intelligent, extremely flexible and very affordable product.
ThePD-155 is designed to accommodate numerous applications, can be adjusted intelligently to any environments and virtually eliminating false detection.
On the front panel, the four selectable loop frequencies (20~80 KHz) can completely eliminate any crosstalk.
If intermittence happen or failed loops get self-healed, the detector will resume to normal operation without manually reset the detector.

Ticket Dispensers Single Loop detector , Traffic Barrier Gate 10MS - 90MS
Application:
The PD-155 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.
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 . 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 4 different setting by turning the trimpot with 0 being the least sensitive and “4” 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 PD-155 vehicle loop detector is compatible with most gate operators. The PD-150 may be used in Center, Safety and Exit loop positions.Fifteen sensitivity settings allow for fine adjustment of the detection level.
