Ratio pyrometers with fiber optic cable

A 2-color low temperature fiber optic pyrometer ideal for industrial applications. Has various temperature ranges from 300°C to 2300°C. All parameters are adjustable via push-buttons displayed directly on the device. Multiple wavelengths available through 2 channels.



The digital ratio pyrometers PSC-GRF11N series are specifically designed for industrial temperature measurement starting from 300°C. The 2-color model has a wide temperature range of measurement, independent of emissivity.

The cast aluminum housing with fiber optics cable allows usage in harsh environmental conditions. The bright temperature display is visible over a long distance. With a fast response time of 5 ms (t95) these pyrometers are suitable for quick measurement processes. The variable focus fiber optical lens provides spot sizes from 0.7 mm in diameter. The integrated laser provides precision aiming to the measured object. The linear temperature output signal of 0/4 to 20 mA makes it easy to incorporate the pyrometer in existing measurement and control systems. The optical lens and fiber optic cable have a high ambient temperature rating of 250°C (482°F).

The device is equipped with a galvanically isolated RS-485 interface, which allows parameterizing & software evaluation even in bus systems. All parameters are adjustable via push-buttons and displayed directly on the electronics box. By using the convenient parameterizing & evaluation software PSCSpot, settings can easily be adjusted from a PC.
