Conquest 4-Principles of Operation
The amplitude of the PCD responses depends on the amount of current, cable depth, wire
separation distance and degree of twist. The PCD response can vary over a wide range,
typically from double digits to 10,000 or more (Figure 4-19).
Figure 4-19:The strength of the magnetic field generated depends on the nature of the wire: single wire,
pair or twisted pair and the spacing. It also depends on the depth of the wire and amount of current flowing
in the wire. PCD values can vary over a wide range depending on these factors.
