7505-type eddy current flaw detector quickly and easily detect conductivity intuitive 0.5-60 s / m tiny cracks on the surface of metal or folding, and is not affected by the oxide layer of the metal surface, paint, oil and other films. Within a certain range, direct readout crack values. (Also used for the classification of the alloy metal grades conductivity difference).
Plane or rules sample, the equipment can be very effective detection, equipped with a special probe or other fixture can be detected the recess edge crack as well as the inner bore, the inner wall of the conical crack.
7505 is a portable instrument, compact structure, small size, light weight. In addition, the instrument using state-of-the-art devices and reasonable layout, higher sensitivity and stability. Therefore, it is suitable for the production and research of mechanical metallurgy and other industrial sectors, such as aircraft and engine maintenance in the aviation industry and simulation experiments, railway locomotive valve (the valve core) detection.
1. Detection range:
(1) the conductivity in the 3-60 ms / m, non-ferrous (non-magnetic) metal
(2) The conductivity of 0.5-4.0 MS / m of iron (magnetic) metals and austenitic (stainless steel)
2. Detection sensitivity:
On the smooth surface (roughness of less than 10um) can be detected 50um longitudinal cracks, crack width is more narrow, the higher the sensitivity.
Probe edge effects: Distance ≥ 6mm
Battery life: Continuous use about 100 hours (do not lift the "trigger" button)
Intermittent use about 200 hours
Working conditions: 0-40º C
