Flaw Detector PCE-FD 20

PCE-FD 20 is a portable ultrasonic flaw detector with a large LCD screen that displays A-scan maps of ultrasonic signals as well as B-scan cross sections. Ideal for use in mechanical engineering, aerospace and metallurgical applications, this high-frequency ultrasound-based defectoscope uses a contact transducer (two different probes included; 45° and 90°) to measure material thickness and identify flaws and defects such as discontinuity in welds. - Operating frequency range: 1 ... 10 MHz - Measured time interval range: 6 ... 1000 microseconds (µs) - Sound velocity: 1000 ... 9999 m/s - Implements shadow, echo and mirror-shadow testing methods - Features a USB interface for downloading data to PC for detailed analysis - Lightweight - Battery or electric power - 1.5 m long probe cable Technical specifications Operating frequency range 1 ... 10 MHz Measure time interval range (scan duration) 6 ... 1000 microseconds (µs) Sound velocity range 1000 ... 9999 m/s Deviation of measurement of time intervals Not exceed ± 0.025 µs Max. deviation of amplitude of signals at receiver input in 0 ... 110 dB range Not exceed ± 0.5 dB Testing gain region 125 dB Averaging over the quantity of starts 1 ... 16 Range of time-variable gain (TVG) / Number of control points TVG 40 dB / 15 Duration of excitation pulse to load 0 ... 0.5 µs Amplitude of excitation pulse to 50 Ohm load, not less 100, 200, 300 Operating frequency range of receiver at -3 dB 1 ... 10 MHz Deviation of amplitudes of input signals in 10 ... 100% range of screen height Not more than 1 dB Scanning 1 ... 1000 µs Scanning delay 0 ... 2000 µs Measurement range of time intervals 0 ... 1000 µs Prism of probe delay 0 ... 15 µs Automatic signaling of defects (AFS) Dual-gate Setting range of AFS gates 0 ... 2000 µs Adjusting thresholds of AFS gates 0 ... 100% Detection of signals (receiver) Positive half-wave, radio mode Dimensions of device (approx.) 80 x 162 x 35 mm / 3.14 x 6.37 x 1.37" Dimensions display (approx.) 48 x 74 mm / 1.88 x 2.91" Power supply 100 ... 250 V AC or 3 x 1.5 V AA batteries Weight (approx.) 250 g / 0.55 lb (without batteries) Delivery Scope 1 x PCE-FD 20 flaw detector 1 x probe cable (1.5 m long) 1 x contact transducer probe (90 °) 1 x contact transducer probe (45 °) 3 x 1.5 V batteries (AA) 1 x battery charger / electric power supply 1 x USB cable 1 x user manual
