Optris CTratio – Precision under Extreme Conditions
The Optris CTratio series is the first choice for non-contact temperature measurements in demanding industrial environments, especially in metal processing. With its two-color ratio technology (also known as ratio pyrometry), it delivers reliable and precise measurements at temperatures up to 3,000°C, even under the most difficult conditions – where conventional single-wavelength pyrometers reach their limits.
Reliable Measurement in Dust, Vapor, and IR Attenuation
In industrial processes, factors such as dust, water vapor, smoke, or IR-attenuating viewing windows are often unavoidable. CTratio sensors intelligently compensate for these influences: Even with signal attenuation of up to 90%, they still measure precise temperatures – ideal for processes in closed chambers or in areas of the plant that are difficult to access.
Independent of emissivity and measurement geometry
The ratio technology of the CTratio series is particularly effective for materials with low or changing emissivity – e.g., metals, oxides, or highly reflective surfaces. Even if the measurement object is small, moving, or difficult to focus, the temperature measurement remains precise and stable.
Highest temperature resistance – without water cooling
Another unique selling point is the extreme heat resistance: Both the sensor and the fiber optic cable can withstand ambient temperatures of up to 200°C without external cooling. For applications under particularly harsh conditions, an optional high-temperature version is available for use up to 315°C – reliable and cost-effective.
The CTratio series from Optris combines intelligent ratio measurement technology with maximum durability. It is the perfect solution for industrial high-temperature environments where reliability, precision, and robustness are crucial.
