Non-Intrusive Pig Signallers

Pigtek Non-Intrusive Pig Signallers offer high reliability for accurate detection of virtually any type of pig. Other advantages over mechanical penetrating signallers include no leak risk, they can be tested in their fitted position, they cannot seize and they can be fitted on the 'live' side of ESD valves.

Pigtek Non-Intrusive Pig Signallers can be supplied as temporary or permanent installations and have a number of fitment options depending upon application. Equipment can be certified (Ex I, Ex d, Ex m) or non-certified, and can be used for onshore, offshore or subsea applications.

Our signallers work on the principal of detecting a change in magnetic field as the pig passes beneath the sensor. Therefore, the pigs must be fitted with a magnetic activation package. Pigtek can supply suitable magnetic activation packages for simple installation to an existing pig. We can supply complete signalling systems that would include Pig Signallers together with purpose built pigs that would be fitted with magnetic activation packages.
