EMTX30 Series (Inc Ex Rated)

Precision In Every Pipeline

Customise your tracking, extend operational efficiency and ensure project success. 

Tailored Tracking

Our transmitters can be customised as required - for example the transmitter power level can be adjusted to achieve the optimum balance between signal strength and battery life.  Additionally, different pulse rates allow for differentiation within a pig train. 

Extended Battery Life with Power-On Options

With our Power-On endcap options, transmitters can be activated when launched rather than when loaded.  This means that pigs can be loaded in advance of the pig run without depleting battery life. 

Config App - Control in Your Hands

No more standard transmitter.  With our intuitive Config Apps, you can adjust signal strength, pulse rate and other parameters without returning to Online Electronics, providing additional flexibility. 

Precise Detection

An inherent electromagnetic null spot is detectable using an electromagnetic antenna meaning that the operator can confirm the location of the transmitter to within a few centimetres.  This greatly reduces vessel and operational downtime by facilitating the process of locating a stuck pig or confirming if a pig has left the launcher or been successfully received. 


  • Designed for pipe sizes of 8"-12"
  • ATEX and IECEX rated allowing it to be used in pipelines with hazardous area classifications
  • The transmitter can be adapted to become the pig body by fitting pig discs. This effectively increases the received signal as it no longer needs to propagate through the pig body in addition to the pipeline wall
  • Bluetooth connection allows the transmitter parameters such as pulse rate, pulse width and power output to be modified by the user
  • Battery life can be conserved with the addition of a Pressure Switch, Water or Magnetic Activation Endcap all of which are easily changeable
  • Can be interfaced with an external piece of equipment such as an Online Smart Gauge Plate to confirm the integrity of any pipeline
  • Can be manufactured with titanium housing for high pressure applications
