Inspection Tool Transmitter Family
For over a decade CDI has been designing and manufacturing a family of custom, high-quality location and tracking transmitters for use in inline inspection (ILI) vehicles such as ultrasonic, magnetic flux leakage (MFL) and caliper tools.  These transmitters do not normally have a pressure housing, but instead are designed to mount inside of the tool and draw their power from the tool's batteries.

For maximum design flexibility these transmitters can either be "all-in-one" cylinders with flying leads or they can have their driver electronics packaged separately from the coil for maximum use of available space.

The ILI tool's computer can have as much or as little control over ON/OFF fuctions and emitted pulse pattern as it likes using simple I/O control signals, therefore, it is possible to use a transmiter for SOS signalling only and have it draw mere microamps during a run.  Existing transmitter designs accept 9-36VDC and have RMS current ranges from 36-638mA.

ILI tool transmitters with integrated driver PCBs:

• CD42-T0 MPS
  ILI tool transmitter with integrated driver electronics for use in 12" and smaller diameter pipelines.
  
• CD42-T1 MPS
  ILI tool transmitter with integrated driver electronics for use in 12" to 28" diameter pipelines.
  
• CD42-T2 MPS
  ILI tool transmitter with integrated driver electronics for use in 28" and larger diameter pipelines.

ILI tool transmitters with remote driver PCBs:

• CD49-SC
  ILI tool transmitter coil with separate driver electronics for use in 24" and smaller diameter pipelines.
  
• CD49-LC
  ILI tool transmitter coil with separate driver electronics for use in 24" and larger diameter pipelines.
  
• CD49-PCB
  ILI tool transmitter driver electronics for use in all tools and pipeline diameters.
