Easy to install and easy to read – the Remote indication System lets you see passage LEDs up to 100 meters away. The Uni-Sig Non-Intrusive Pig Signaller is completely nonintrusive and easily bands to the outside of pipelines from 2” to 60”. Since the Uni- Sig Non-Intrusive Pig Signaller is non-intrusive corrosion problems are avoided and installation can take place without hot-tapping or interrupting the flow of the system. Once installed the Uni-Sig Non-Intrusive Pig Signaller immediately begins scanning for both transmitter and permanent magnet equipped pig passages, and displays times and dates along with a “Recent Passage” message. A simple scroll through the Uni-Sig Non-Intrusive Pig Signaller memory reveals the last ten passages’ times and dates. The Uni-Sig Non-Intrusive Pig Signaller operates for a full year on just two standard D-cell alkaline batteries or can be connected to an existing 24VDC power. With the Uni-Sig Non-Intrusive Pig Signaller you can: ? Install it quickly and easily by simply banding it to pipelines from 6” to 60” with wall thicknesses of up to 1.5”. ? Detect both transmitter and permanent magnet equipped pipeline pigs. ? Install anywhere on a system without paying extra for explosion rated location due to the unit’s fully certified explosion-proof housing (with tempered glass window). ? Install either above or below ground. ? Retrieve the unit’s ten most recent pig passage times and dates ? Install just two D-cell alkaline batteries for a full year’s operation ? Utilize the suspend option which allows the system to be moved to different locations on your pipeline The Uni-Sig Non-Intrusive Pig Signaller detects pig passages with both permanent magnets and transmitters. Each method has distinctive advantages: Magnets: ? Small, powerful and inexpensive ? No batteries required

Testing on a continuous cyclic hot-cold has clocked up in excess of 3000 continuous hours until the release of this data sheet and will continue to be tested until failure occurs we could have a long wait!
