Aerospace Applications
Ultrasonic Thickness Measurement


  • Measure wall thickness of aluminum sheet after chem milling
  • Check thickness of components after CNC machining
  • Incoming thickness inspection of steel or aluminum coils
  • Thickness of plastic windows and cowlings
  • Requires access to only one side (typically outside) of component

Recommended Gauges
  • TM1 CD
  • TM1 CDL with datalogger for permanent documentation of thickness readings
  • T-Mike E (for plastic windows and cowlings)
Ultrasonic Flaw Detection


  • Locate disbonding in composite materials
  • Locate and size discontinuities in structural components
  • Also addressess thickness measurement applications

Recommended Instrument

Ultrasonic Bolt Stress Measurement


  • Controlling the tightening of bolted joints in the engines of the space shuttle
  • Verify the tension on bolts clamping aircraft wheel assemblies
