Page 7: Loop Installation
Loop Installation An inductive loop consists of a single length of wire, usually 12 to 18 gauge, wound in a square or rectangle shape often sawcut into the pavement. Both ends of this wire are brought back to the detector and connected to the ‘loop’ positions as designated on the unit. With the loop properly connected to the detector and the detector unit powered up, a field will be generated around the loop. -
Page 8: Helpful Tips
Detection height is a major factor in reliably detecting vehicles of interest. A good rule of thumb is that the small side of the loop will determine field height and provide 1/2 to 2/3rds that distance in detection height. Ex: 6’x4’ loop (4 foot side determines height) will have a field height of 24” to 32”. Ex: 10’x6’...
