CINCINNATI, Ohio -- Process Pigging Systems has unveiled new pig detectors for the cleaning of pipeline systems. Featuring a non-intrusive magnetic sensor and with no mechanical parts, these detectors use a magnetic field to locate the pig in the pipeline.
The detectors are powered by 12 – 24 Vdc providing a 'pig detected' output via volt-free contacts which can be utilized in a number of ways depending upon the application. Designed for use with industrial PLC systems, they include a configurable stretched output pulse to compensate for the PLC scan time lag.
The detectors can be supplied separately or as part of a pigging system which allows the injection of the pig into an encapsulated sanitary system to recover product or remove cleaning fluids from the pipeline between batches. Pigs are propelled through the pipeline by compressed air, nitrogen, carbon dioxide, water, or the next material to be used in production. This form of pigging commonly provides product recovery of 99%, allows faster product changeovers, reduces water consumption by up to 50%, and allows companies to reduce their CIP chemical consumption by up to 30%, the company says.
