Magnetic Pig Sensors
Pigging system operation requires periodic confirmation that pigs have reached their target destination.  Magnetic Pig Sensors are mounted externally on the transfer pipeline and detect the presence of a magnet imbedded in the pig.  Pig detection triggers an LED that visually confirms for the operator a pig is present.  Outputs from the Magnetic Pig Sensor can signal an automated control system and be used to trigger auxiliary devices such as strobe lights and horns.  In addition to stationary pig detection, the Magnetic Pig Sensor can also uniquely provide detection of a moving pig and confirmation of pigging progress at key points in a long transfer line.  The Magnetic Pig Sensor has adjustable sensitivity levels and is designed to work in conjunction with the specially selected magnets imbedded in the Production Pigs to provide reliable detection through both carbon and stainless steel.
