Radiation Pyrometers / Hot Metal Detectors

Radiation pyrometers or 1-channel pyrometers measure as opposed to 2-color pyrometers (ratio pyrometers) only on one channel (one wavelength range). With such devices, most measuring object temperatures can be well determined. Radiation pyrometers are available in many different designs, the selection is based on measuring temperature / measuring material, spectral range, response time / exposure time, environmental conditions, features, housing design.

Radiation pyrometers or hot metal detectors are available in the following housing designs / series:

Short-Wave Measurements

metals, ceramics, glass, composites, semiconductor, wafers, molten glass…

Spectral range graph for metals

The material to be measured largely determines which spectral range of the pyrometer should be selected. For metal measurements, the shortest possible spectral range for a precise measurement is advantageous. Due to technical reasons the beginning of a temperature range may be limited, to a higher starting temperature therefore a model must be selected with a slightly higher spectral range, e.g. longer wavelength.

Spectral range graph for non-metals

Other materials are usually measured in specially rated pyrometer wavelengths found by material analysis as suited for this purpose. The field of application is explained by the respective pyrometer models, but also we are pleased to advise you or support you in the emissivity determination.
The presented application mapping is not complete, many of the available spectral ranges can be used in various fields. We recommend a pre-advice before you decide on a device.
