To locate a pig equipped with a SPY® Transmitter, the SPY® PTR (Pig Tracker Receiver and Wand) registers the changing magnetic field produced by the SPY® Transmitter. When the Transmitter is located, the PTR produces both an audio and visual output. With two standard 9-volt alkaline batteries, the PTR can be powered continuously for approximately 50 hours. Special wands are available for sub-sea applications, with depths of up to 10,000 feet [3000 meters].
With TRAXALL 620 can track each of up to three transmitter frequencies are represented as scrolling rows of LEDs. This intuitive user interface means that the TRAXALL 620 receiver requires very little training and support, lowering the total cost of ownership of the system.
TRAXALL is CDI's major advance in state-of-the-art pipeline pig location and tracking. Building upon 20 years of tracking know-how and our sophisticated new Digital Signal Processing (DSP) technology, the 770 tracks as many as 7 different transmitter frequencies simultaneously with a unique color assignment for each on the bright, wide temperature display.
