INTRODUCTION
Detection Methods
The CD52 Bandit detects pig passages via two very distinct methods:
permanent magnets and electromagnetic transmitters. The advantages
to each method are discussed below.
Permanent Magnets
The Bandit will detect rare earth permanent magnets attached to a
pipeline pig. Magnets for this purpose are sold by CDI and are available
for pipelines from 2 in. to 60 in. [50.8 mm to 1524 mm].
