Metal Selection Guide

Which pyrometer is suitable for which metal?

When performing noncontact temperature measurements on metals, the pyrometer used must be suitable for the specific temperature range and the surface of the material. The following overview shows typical melting points of various metals and serves as a quick guide for selecting a suitable industrial pyrometer.

Overview of the preliminary selection of industrial pyrometers based on the melting temperatures of various metals. For the final device selection, other factors—including emissivity, wavelength, measurement spot, surface, and installation conditions—are also relevant.
Low to Medium Temperatures Depending on the metal, surface, and measurement task, suitable pyrometers are available for low- and medium-temperature ranges.
Medium to high temperatures For processes such as forging, casting, hardening, or heating, pyrometers with a correspondingly extended measurement range can be used.
High-Temperature Applications For very high metal temperatures, specially designed industrial pyrometers with the appropriate spectral range are required.

Pyrometer Manufacturers for Industrial Temperature Measurement

Maurer develops industrial pyrometers for noncontact temperature measurement in manufacturing, mechanical engineering, and the process industry. Depending on the application, universal pyrometers, compact pyrometers, two-color pyrometers, and high-speed pyrometers are available for various materials and temperature ranges.

Industrial Pyrometers for Precise Temperature Measurement

We develop and supply industrial pyrometers for noncontact temperature measurement in manufacturing, mechanical engineering, and the process industry—precise, fast, and suitable for a wide variety of materials and temperature ranges.

What is an industrial pyrometer?

A pyrometer measures the temperature of an object without contact, based on its thermal radiation. This makes it possible to monitor even very hot, moving, or hard-to-reach objects directly during the production process.

✓ Noncontact temperature measurement
✓ Fast response and measurement times
✓ For low and very high temperatures
✓ Integration into machines and production facilities

Applications of Industrial Pyrometers

Industrial pyrometers are used wherever temperatures need to be measured quickly, precisely, and without direct contact with the object being measured.

Notes

  • The melting points can vary depending on the purity and alloy composition
  • Steel is an alloy of iron and carbon, therefore not a pure metal
  • Tungsten has the highest melting point of all pure metals
  • Aluminum melts at a relatively low temperature, which makes it easy to process
