Type PASSIVE NON-INTRUSIVE ULTRASONIC SIGNALLER The Ultrasonic Passive N-I Pig sig is a fully ATEX and IECEx certified, non-intrusive pig signaller which quickly and accurately detects, signals, and logs the passage of pigs at critical points along a pipeline both on land and offshore. Key benefits: • • • • • Use of the Pig Sig can result in time and therefore cost savings during pigging operations. Removes any uncertainty over confirmation of pig passage. Quick and easy installation using ratchet straps or steel banding. Minimal set up required ensuring time is not lost setting up multiple parameters. Suitable for all pig types - no transmitters or magnets are required to confirm passage or location in the receiver. • Suitable for gas and liquid pipelines. • Main housing can be mounted remotely for use on buried pipelines or where access if limited. The Ultrasonic Passive N-I Pig sig monitors the acoustic emissions created by the vibrational and acoustic noise generated as a pig moves through a pipeline. The unit then processes the emissions to identi-fy the signature of a p

Events are signalled as they occur via a graphical display and high brightness LED. The unit logs the time and date of up to 99 events. Logged events can be viewed locally on the display or transmitted remotely over several optional interfaces. The user can turn the unit ON and OFF as well as modify several settings using the single control button and intuitive menu system. The Ultrasonic Passive N-I Pig sig has two basic parts, main housing and sensor. The sensor is permanently connected to the main housing via a cable and can be quickly and easily attached to the pipeline using ratchet straps...
