High temperature feet

For measurements of hot surfaces you need to consider that metals change their magnetic and electrical properties at higher temperatures. When measuring on hot surfaces with our gauges from the Surfix® family with standard probes (0.2 and 1.5 mm measuring range), calibration is usually not necessary, owing to the non-sensitivity of the sensor to permeability and conductivity changes.

Phynix offers two high temperature feet for measurments on hot surfaces:

  • Hot coating measurement up to 150°C, e.g. freshly burnt-in powder coatings, can be measured with Surfix® E, Surfix® S oder Surfix® Pro S. In such cases you should use the fawn-coloured contact ring (Product No. 10098) made of heat-resistant plastic.

  • Hot surfaces up to 300°C can be reliably measured with the high temperature contact ring (Product No. 10844). The required modification of the measurement probe FN 1.5 or F 1.5 (measurement range 1.5 mm) can be carried out quite easily by attachment of the screw contact ring. This contact ring can measure thicknesses of up to 1,000 µm on hot surfaces.
