Function
Wöhler VIS Ø 40 mm and Ø 26 mm camera heads are equipped with a transmitter coil
that transmits signals at a frequency of 8.9 kHz or 9.2 kHz (depending on the region).
Three coils inside of each handgrip of the Locator measure magnetic fields. When the
user holding the Locator approaches the camera head the measured magnetic field gets
stronger.
By calculating the difference in intensity of the signals received from the different coils,
the Locator is able to indicate in which direction the camera head is located as seen from
the Locator.
A cursor in the display and an acoustic signal enable the user to locate the exact position
of the camera head in the pipe.
