Induction Loop Installation

Manual for the installation of induction loops

Inductive impulse transmitters are the most frequently used devices for the detection of vehicles of all sorts. The induction loop as sensor of these inexpensive devices is characterized by its robust and weather-independent structure.

The advices for the laying of loops relate to the following areas of use:

Gates:

Automatic opening and closing of gates, shutters, barriers, etc.

Parking lots:

Motitoring of single parking spaces
Control of barriers
Counting in parking garages

Rail-bound vehicles:

Opening and closing of hall gates
General detection for other control purposes

The following features apply for the induction impulse transmitters:

  • Microprocessor controlled
  • Static hold time
  • High sensitivity of max. 0.02% Df/fo
  • Multi-channel version, max. 4 channels
  • Wide operation range 10 µH - 2000 µH
  • Temperature compensation
  • Automatic alignment

These characteristics are typical values, the characteristics indicated in the data sheet of each device must be observed.

For most applications, the induction loop is laid in a square or rectangular form. Depending on the loop’s circumference, a different number of turns must be laid into the loop slot.

For detailed information about induction loops and the laying of induction loops see the manual in the download area at the right margin.
