• What is the Use of a Coating Thickness Gauge?

• Thickness gauges are very widely and
  regularly used in manufacturing industries. They
  are used in determining the gauge or thickness of
  a material. Many types of gauges are there and
  each of them has a different function. It is
  mainly based on the intended application of the
  gauge. They are

• Material thickness gauges

• Wire and sheet metal thickness gauges

• Coating thickness gauges

• The first is used for gauging the material
  thickness by mechanical means. You need to close
  a calibrated instrument around the sample until
  contact is made with both sides of the material.
  In Steel Manufacturing and Iron
  Manufacturing industries, these gauges are widely
  used..

• The second type of gauge is a simple
  mechanical device. It can be used for measuring
  the thickness of wire and sheet metal. In a wire
  or sheet metal manufacturing industry, or in
  the Metal Products Manufacturing industry, this
  gauge is useful.

• The third category is what we are going to
  talk about in this blog. It is designed to
  measure the thickness of coatings applied to a
  surface. That is the reason, it is called
  a coating thickness gauge.

• What are the Applications of Coating Thickness
  Gauges

• In some applications, there is a need to
  measure the thickness of a coating. For example,
  paint applied on paint or insulation applied on a
  cable. Here, other gauges like material thickness
  gauges are not useful. Only coating thickness
  gauges (sometimes referred to as paint meters)
  can be useful in this case. It assures that the
  coating complies with the required standards.

• Among them, two types of coating thickness
  gauges are popular. The simpler of them is a
  process where the gauge pierces through the dry
  coating down to the substance and establishes the
  coating thickness directly. The wet gauges
  measure the thickness before the coating dries.

• The second type of coating thickness gauge is
  the non-destructive type. They use many methods
  to achieve that, but the most widely used is the
  use of ultrasonic waves. It uses an ultrasonic
  transducer, which emits a pulse of sound wave
  energy into the coating. When it hits the
  material boundary, a reflection occurs and sends
  a return pulse back to the transducer. The time
  difference is measured, and the thickness of the
  coating is established.

• A magnetic thickness gauge determines the
  thickness by using a magnetic field.  It uses an
  estimate of the force required to pull a magnet
  away from the coated substrate to measure the
  thickness.

• MEXTECH is one of the best companies for
  providing a wide range of test and measurement
  instruments in India. For over years they have
  been a leading manufacturing company specializing
  in digital multimeters, clamp meters,
  thermometers, Thermo hygrometers various other
  instruments.
