Loop detectors (Dmgdeh)

Sensors capable of detecting vehicle passage and presence. They consist of four parts: one or more turns of wire embedded in the pavement; a lead-in wire running from the wire loop in the pavement to the pull box; a lead-in cable spliced to the lead-in wire at the pull box, which connects to the controller; and an electronics unit housed in the controller.
