Hall Effect Wall Thickness Measurement with Presto's Magnamike 8600

Magnamike – 8600 is the best wall thickness gauge which works on Hall Effect principle of thickness measurement. It is a very light in weight and portable device which is designed to solve the purpose of accurate and repetitive measurement of non- ferrous elements such as glass, plastics & composites, titanium, and aluminum. The very first and commercial, widely used testing device was introduced in the year 1980 and nowadays used in most of the companies. Non-destructive type of testing is performed to assess the thickness of wall just by placing a small target ball inside the test sample and magnetic probe on the other side. Magnamike 8600 quickly ascertain the difference between the wall and magnetic probe and displays the result on the digital display.

What Products can be measured with Hall’s Effect?

Hall Effect gauge is widely used to measure the non-magnetic material whose geometrical principle helps to place a ball inside the sample and probe tip on the other hand that measures the thickness of approximate 1 inch to 25mm. The materials that can be measured with Magnamike 8600 includes aluminum, plastics, composites, and other non-ferrous materials such as glass, wood, metals, paper products and also some non-magnetic S.S. alloys. The testing device measures the wall thickness with the best rate of accuracy i.e. +/- 1%.

Applications of Wall Thickness Gauge

  • Airbag tear seams
  • Plastic bottles & packaging products
  • Molded parts of plastic containers and tanks
  • Small diameter plastic and nonmagnetic metal tubing
  • Scientific glassware & Glass containers
  • Paper and foam food containers
  • Aluminum beverage Cans
  • Aerospace parts inclusive of turbine blades
  • Machined metal parts
  • Particle board and plywood

How does a Wall thickness gauge work?

Magnamike – 8600 is a specialized automatic semiconductor device which instantly responds when a little change in the magnetic field is observed with a varying voltage when a current passes through the surface of the probe. When a Hall Effect based thickness measurement gauge is used, it is clearly meant that a small probe along with a magnetic ball is creating a magnetic field around the sensor. As the thickness of the sample wall and distance between the magnet and probe changes which depicts the inaccuracy in the wall thickness also changes the voltage across the Hall Effect sensor in an anticipated manner.
