loop detector,our loop detectors are the bestsellers over the world and we have over 10 years experience in this field.

loop detector VD108B

Installation guide:      

The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation location must choose to stay away from the heat source; it around other devices must maintain a distance of at least 10mm (must not installation close with boxes wall)A correct loop configuration and detector installation will ensure a successful inductive loop detection system. Loop of several important parameters include: loop figure, size, turns, install methods (details as detector installation guide)
