INTRODUCTION
INTRODUCTION
The CD52 Bandit is a computerized electronic device for non-intrusive
detection of pipeline pigs equipped with either a permanent magnet or
22 Hz electromagnetic transmitter.
The Bandit accomplishes this by a proprietary and patented magnetic field
antenna array located in its base and attached to (or near) the pipeline.
This antenna array signals an on-board computer if and when a pig
passage has occurred.
When a pig passage is detected, the time and date of passage are recorded
into the on-board memory of the Bandit and displayed on an LCD screen.
In addition to the most recent pig passage time and date, the Bandit
remembers the dates and times of the previous nine pig passages as well.
An operator may quickly and easily retrieve the dates and times of the 10
most recent pig passages via the Bandit's user interface.
