TQ-92 – Acoustic flaw detector

Acoustic flaw detectors

The handheld instrument tailored for detecting delaminations and other material defects through manual scanning of the inspection area.

Application

The instrument is indispensable for non-destructive testing of bonded or laminated components using Mechanical Impedance Analysis (MIA). It finds utility in testing:

  • Multilayered laminates
  • Fiber-laminate materials
  • Laminate-honeycomb bonding
  • Laminate-metal bonding
  • Metal-metal bonding
  • Metal soldering
  • Metal-feltmetal brazing
  • Hard and soft foams
  • Wood laminates

Operational advantages

  • High detection capability and spatial resolution within an inspection range from 0.15 mm to 13 mm
  • Extra-light and compact electronic unit for comfortable fieldwork
  • Dry coupling of the sensor eliminates the need for coupling liquid
  • Stable and reliable indications ensured by the constant pressure of the spring-loaded sensor
  • Simple instrument operation and clear interpretation of inspection results

Construction advantages

  • Rapid start: minimal training required for new operators.
  • Easy calibration: automatic sensor calibration on the inspection object.
  • Stable and reliable operation on rough/uneven surfaces due to the spring-loaded sensor design
  • Customized sensor design available for specific material combinations

Possible sources of material defects

  • Impact damages by foreign objects
  • Hail and lightning strikes
  • Loss of strength caused by heat
  • Thickness variations
  • Osmosis damages of fiberglass boats
