FRU manufacturer price WH92 thickness gauge Automatic identify ferrous and non-ferrous substrate for small area
Principle:
The device uses magnetic thickness measurement method, which non-destructively measures thickness of non-magnetic coating (such as: aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloy and hard magnetic steel, etc.).
Magnetic Method (F-type probe)
When the probe contacts the cover layer, the probe and magnetic
substrate forms a closed magnetic circuit; Due to the presence of
non-magnetic coating, magnetic resistance changes. The thickness of
the cover layer can be derived by measuring the change.
Eddy Current Method (NF-type probe)
When the probe contacts the cover layer, the probe and non-magnetic
substrate forms Eddy Current and gives feedback to the coil inside
the probe.
The thickness of the cover layer can be derived by measuring the
feedback.
1) Thickness measurement using both Magnetic Method to measure the
non-magnetic coating on a magnetic metal substrate and Eddy Current
Method to measure the non-conductive coating on a non-magnetic
metal substrate.
2) Single-point or two-point method could be used to correct probe
system deviation, in order to ensure the accuracy of the device in
the process of measuring.
3) Automatic identify ferrous and non-ferrous substrate quickly.
4) Power voltage indicator.
5) Speaker beep while operating.
6) Power-off automatically when idle; manually power-off available.
7) Negative display function to ensure the accuracy of zero point
calibration.
