Coating Thickness Gauges

Coating Thickness Gauges


Amruta Electronics offers Coating Thickness Gauge. These are used for measurement of non magnetic coating on magnetic surfaces. Principles of operation: it works on principle of electromagnetic induction AC current of constant voltage flows through the coil on core. The current varies in relation to inductance variation of the coil affected by bringing the coil close to or away from the magnetic material. Change in current depends upon distance between the coil and the magnetic material, which implies to the thickness of the coating on magnetic material.

For measurement of following nonmagnetic coatings on magnetic metals

  • plating - gold, copper, zinc, tin chromium, hot dip galvanising
  • Coating - paint, resinous, coating, metallic coating, powder coating;
  • Lining - resin, rubber, glass, etc
  • Film - any other films of non-magnetic material can be measured when placed on steel base metal.

  • Range - microns 0 to 1000
  • Resolution - ±1 micron
  • Accuracy - ±1 micron
  • Min area - 7 mm dia
  • Min radius - convex 3 mm
  • Concave 30 mm; min base thickness - 0.3 mm
  • Supply - dry battery 6f22/9 V
  • Check - battery to be replaced when display shows Lo-Batt
  • Work temperature - 0 to 50°C
  • Size (mm) instrument - 127 x 25 x 40
  • Probe - D14 x L48
  • Weight - 350 gm
