As you may have guessed, this kind of detector works by detecting an inductance change in a wire loop (aka coil) buried in the road. Having a car pass several inches on top of it produces such an ...

and an extensive amount of documentation is available on this if you want to try to roll out your own inductive loop vehicle detector. Of course, this isn’t the only way to detect a vehicle’s ...

Delta Scientific Vehicle Loop Detectors are recommended with all delta and most other vehicle access control systems because they are programmed to prevent a closing signal when power resumes. The NP ...

The PD130 inductive loop detector is the most critical component of the whole vehicle access control system. Single channel loop detectors are used to identify the presence of vehicles by means of an ...
