Acoustic flaw detector TQ-92

phased arrayfor NDThand-held

The TQ-92 is a handheld instrument tailored for detecting delaminations and other material defects through manual scanning of the inspection area. The instrument is indispensable for non-destructive testing of bonded or laminated components using Mechanical Impedance Analysis (MIA). - Application: Testing of multilayered laminates, fiber-laminate materials, laminate-honeycomb bonding, laminate-metal bonding, metal-metal bonding, metal soldering, metal-feltmetal brazing, hard and soft foams, and 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 Technical specifications: - Measurement principle: Mechanical Impedance Analysis (MIA) - Inspection range by two MIA transducers: 0.15 mm to 13 mm / 0.006 to 0.5 inches (depending on material properties) - Flaw detection capability: For laminated components: > dia 8 mm/0.3 inch, For metal alloy bondings: > dia 0.5 mm/0.02 inch with the sizing accuracy 8 mm, metal alloy bondings >0.5 mm, sizing accuracy <25% - Transmitter type: Pulse excitation - Electronic unit dimensions: 159 x 77 x 35 mm - Weight: 0.3 kg - Display: 2.4-inch color TFT, 240x320 - Battery: 3 x NiMH, ≥2,700 mAh, up to 20 hours operation - PC interface: USB - Environmental: 10–50°C, up to 98% humidity at 20°C
