Pyrometer CTratio 1M

The Optris CTratio 1M stands as a stalwart in the realm of temperature measurement, offering a robust and precise solution for non-contact temperature monitoring across a broad spectrum of high temperatures, ranging from 450 °C to 3000 °C. Engineered with meticulous attention to detail, this advanced fiber-optical ratio thermometer is available in three distinct models, namely 1ML, 1MH, and 1MH1, each tailored to address specific measurement requirements with unparalleled accuracy and reliability.

At the heart of the CTratio’s exceptional performance lies its innovative ratio-based measurement principle. Unlike conventional single-color pyrometers that rely solely on intensity measurements, the CTratio employs a dual-color approach, measuring infrared radiation at two closely spaced wavelengths. By evaluating the relationship between these two intensities, the CTratio ensures consistent and repeatable temperature measurements, even in challenging conditions where emissivity may be unknown or vary with temperature.

This ratio-based methodology offers several distinct advantages over single-color devices. For instance, this pyrometer remains resilient in adverse conditions, such as when the measuring spot is partially on the object or when obstacles like dust, smoke, or steam are present in the optical path. Moreover, the CTratio’s ability to accurately measure temperatures when the object is not fully within the pyrometers field of view or is in rapid motion underscores its versatility and reliability in demanding industrial environments.

Aligning the CTratio for optimal performance is a breeze, thanks to its integrated green laser, which provides real-time spot size indication at any distance. This feature simplifies sensor alignment, even on surfaces emitting intense red glow. Additionally, the CTratio boasts motorized focus capability, allowing for adjustable focusing from 150 mm to infinity. This flexibility enables users to effortlessly focus on targets at varying distances, catering to diverse measurement needs.

The optical resolution of the CTratio varies across its models, with the 1ML offering an optical resolution of 38:1 and the 1MH and 1MH1 models providing a higher resolution of 100:1. This variability ensures precise targeting and measurement of small objects or areas, enhancing the instrument’s utility across a wide range of industrial applications.

In terms of accuracy and reliability, the CTratio excels with a system accuracy of ±(0.5% of the reading + 2 °C), measured at an ambient temperature of 23 ± 5 °C. Additionally, the infrared sensors repeatability, measured under similar ambient conditions, is ±0.3% of the reading, guaranteeing consistent performance over repeated measurements.

Safety and durability are paramount considerations in industrial environments, and the CTratio addresses these concerns admirably. Featuring an electrically isolated sensing head, the instrument ensures enhanced safety and reliability, while the infrared thermometers rugged stainless steel housing withstands the rigors of industrial settings.

Designed and manufactured in Germany, the CTratio embodies precision engineering and uncompromising quality. Its adaptability, durability, and accuracy make it the go-to choice for critical temperature control in industries such as metal and semiconductor manufacturing. With comprehensive support for various analog and digital outputs, seamless integration into industrial processes is assured.

In conclusion, the Optris CTratio 1M epitomizes excellence in non-contact temperature sensing technology. Its superior performance, coupled with advanced features and unmatched reliability, makes this pyrometer an indispensable tool for precise thermal monitoring in the most demanding industrial environments.
