Continous Monitoring

HotSense™ ultrasonic sensors for in-service wall thickness monitoring Minimise operational risk and maximise productivity with enhanced asset intelligence. Ultrasonic transducers and system solutions ideal for thickness, corrosion and erosion monitoring for use in applications across refining, oil & gas, energy, nuclear, aerospace and process sectors.


  • Thickness Monitoring
  • Crack Detection
  • Range Sensing
  • Level Sensing

Measurement Made Easy

  • Monitor wall thickness in-service across a wide temperature range -55 to +380 °C
  • Detect wall loss to 0.010 mm (0.001”) Complement inspection and improve repeatability & accuracy with fixed transducers installed directly on to assets
  • Support asset integrity and corrosion management programs (including RBI, FFS & FEA)
  • Reduce costs with replacement of intrusive methods and reduced scaffolding/insulation removal
  • Increased safety with reduced exposure and man-hours at asset
