The FAI SPI-ULTRA501 (Passive) is a fully ATEX and IECEx certified, non-intrusive scraper pig detector which quickly and accurately detects, signals, and logs the passage of scraper at critical points along a pipeline both on land and offshore.
Key benefits of non-intrusive pig detector
- Use of the SPI-ULTRA501 can result in time and therefore cost savings during pigging operations.
- Removes any uncertainty over confirmation of scraper 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 scraper types – no transmitter 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 SPI-ULTRA501 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 identify the signature of a passing scraper.
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 SPI-ULTRA501 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 or steel banding. The main housing contains all electronics, display and the control button and can be mounted onto the pipeline using a mounting plate and straps in a similar fashion to the sensor or mounted on a wall or post.
