To localize and track inspection or cleaning tools during their run, they are usually either equipped with an ITX Transmitter or with strong magnets. The signals of the ITX Transmitter or the magnetic fields can be received by an instrument outside the pipeline.
PETROTECH has developed a new generation of ATEX certified instruments – the Pig Detector.


  • Pig Detector available
  • Monochrome, non-reflcting graphics display
  • Keypad-operated hand-held unit
  • Able to detect extreme low frequency and magnet signals
  • Built-in GPS module (time/location)
  • Bluetooth interface
Pig Detector


PETROTECH’s EPD III device comes with a new ergonomic design, improved graphic display and extended detection capabilities. The electronic tool detector device is used in combination with a transmitter (ITX series), or magnetic signals from in-line inspection (ILI) tools or cleaning tools equipped with tracking magnets.


The EPD includes a hand-held unit, the antenna, an antenna cable for the connection, and the carrier for easy handling of the EPD.
It is part of our tool tracking and locating system. In addition to determining the precise location of a stationary tool, the device can be used for monitoring the passage of a tool.
A tool locating system is basically recommended for use with the following tool types/sorts:

  • Cleaning tools
  • Batch separation using tools
  • Smart tools
  • Leak-seeking tools.
