Dresden, Germany —  DIAS Infrared expands its product range by new ratio pyrometers that allow non-contact temperature measurement already starting from 300 °C.

In particular, the pyrometers were developed for applications in determining metal temperatures and metallurgy.

The ratio pyrometers are suitable for harsh ambient conditions where the risk of contamination of the optics exists.

While ordinary 1-wavband  pyrometers show lower measured values when their optics are contaminated, the measured temperature of ratio pyrometers (two wavebands or colors) change only when there is significant contamination.

In contrast to 1-waveband pyrometers the temperature indicated stays widely stable if the measurement object is a little bit smaller than the measurement field of the ratio radiation pyrometer.

This is for example the case for: moving metal strips, bands, bars or wires.

The core of the new ratio pyrometers is a novel indium gallium arsenide 2-color detector that is based on longtime experience and scientific works in the field of sensor technology and pyrometer development by DIAS Infrared.

The ratio pyrometers of the DIAS PYROSPOT pyrometer series 10 are equipped with vario optics and LED/laser aiming light, through-lens sighting or color video camera (PYROSPOT DGR 10N and DGR 10NV).

A version with fiber optics is available within the PYROSPOT series 11 (PYROSPOT DGRF 11N).
