Measurements |
Dual element transducer measurement mode | Time interval from a precision delay after the excitation pulse to the first echo |
Echo-to-Echo (optional) | Time interval between two successive back-wall echoes to eliminate paint or coating thickness |
THRU-COAT® measurement (optional) | Measurement of true metal and coating thicknesses with a single back-wall echo (with D7906-SM, D7906-RM, and D7908 transducers) |
Single element transducer measurement modes (optional) | Mode 1: Time interval between the excitation pulse and the first back-wall echo Mode 2: Time interval between the delay line echo and the first back-wall echo (with delay or immersion transducers) Mode 3: Time interval between successive back-wall echoes following the first interface echo after the excitation pulse (with delay line or immersion transducers) |
Thickness range | 0.080 mm to 635 mm (0.003 in. to 25.0 in.) depending on material, transducer, surface conditions temperature, and selected configuration (Full range requires single element option) |
Material velocity range | 0.508 mm/μs to18.699 mm/μs (0.020 in./μs to 0.7362 in./μs) |
Resolution (selectable) | Low: 0.1 mm (0.01 in.) Standard: 0.01 mm (0.001 in.) Single Element option: 0.001 mm (0.0001 in.) |
Transducer frequency range | Standard: 2.25 MHz to 30 MHz (-3 dB) High Penetration (Single Element option): 0.50 MHz to 30 MHz (-3 dB) |
