The USM 23 EX intrinsically safe flaw detector - portable and battery powered.
The USM 23 EX is contained in a plastic housing and is designed for operation in explosion endangered areas, according to EN 50020, aimed classes: Eex ib I (gas mine areas) and Eex ib IIA T4 (explosion endangered areas). Only the permitted probes and batteries are to be used when using the instrument in an explosion endangered area.
• Only the permitted probes and batteries are to be used when using the instrument in an explosion endangered area.
According to EN 50020, aimed classes: Eex ib I (gas mines) and Eex ib IIA T4 (explosion endangered areas)Calibration Ranges Minimum 0 to 2.5 mm (0 to 0.1) + 10% (steel long)
Maximum 0 to 9999 mm (0 to 390) + 10% steel long, in the frequency range from 0.1 to 4 MHz)
Maximum 0 to 1420 mm (0 to 56 + 10% steel long, in the frequency range from 2 to 10 MHz) Sound Velocity Range 1000 to 15000 M/S (40 to 600"/ms) variable in steps of 1 m/s (0.1"/ms) and fixed programmed values Pulse Shift -10 mm to 1024 mm Probe Delay 0 to 99 �s Damping 50 ohm, 500 ohm Pulse Power 1 nF, 2 nF Frequency Range (03dB) 0.1 to MHz, 0.5 to 4 MHz, 0.8 to 8 MHz, 2 to 15 MHz Pulse Repetition Frequency 4 - 1000 Hz; adjustable in 10 steps Gain 110 dB, adjustable in steps: 0 (locked) / 0.5/1/2/6/12 dB Fine Gain 4 dB, continually in 40 steps Rectification Full wave, negative and positive halfwave Suppression Linear, 0 to 80% of the display height, adjustable in steps of 1% Monitor Gate Individual gates in bar presentation, start and width are adjustable over the complete calibration range, threshold is adjustable from 10 to 90% of the display height in steps of 1% (coincidence and anticoincidence), alarm signal via LED or switchable, internal horn. Adjustable double gate for measurement of the sound path difference between two echoes, threshold and start point of the two gates. Sound Path Measurement Digital indication of the sound path (projection distance, depth) between initial pulse and the first echo in the gate, or between the echoes in the double gate; measurement at the cross point with the echo flank or echo peak. MeasurementResolution 0.01 mm to 99.99 mm sound path
0.1 mm from 100 to 999.9 mm sound path
1 mm over 1000 mm sound path
0.001" for sound path up to 390" (full range)
