CCL & GR Perforating Casing Collar Locator - Perforating (CCL)
As the tool passes a collar, or change in metal volume, lines of magnetic flux between two opposing permanent magnets are disturbed. This causes a low frequency voltage or Electro Magnetic Field (EMF) to be induced in a coil, mounted between the permanent magnets. Finally the signal is converted by a voltage-controlled oscillator for recording in the section of the tool.
