Optris Expands CTi Pyrometer Series with Reliable Infrared Sensors

Berlin, Germany – Optris GmbH & Co. KG announces the expansion of its successful CTi pyrometer portfolio with the introduction of the new CTi 1M and CTi 2M models. Designed for demanding industrial environments, both infrared sensors provide highly accurate non-contact temperature measurement for metals and high-temperature applications while maintaining the compact and modular CTi platform design.

The CTi 1M operates at a short wavelength of 1.0 µm and covers temperature ranges from 350 °C up to 2200 °C, making it particularly suitable for steel, tungsten, iron, and semiconductor processes. Its fast exposure time of 110 µs and response time of only 320 µs enable reliable monitoring of rapid thermal processes, while an optical resolution of up to 75:1 ensures precise measurements even at longer distances.

Complementing this model, the CTi 2M features a 1.6 µm spectral range optimized for lower metal temperatures between 150 °C and 2000 °C. The short-wavelength design minimizes measurement deviations caused by emissivity changes and reflections, providing stable readings in real production environments. With its miniature sensing head and robust stainless-steel construction, the sensor integrates easily into confined machinery installations. Both CTi M innovations feature an even lower starting temperature than the previous CT series.

CTi LTfast: High Speed Measurement for Dynamic Processes

With the CTi LTfast, Optris introduces a solution tailored for extremely fast control and monitoring applications. Covering a wide temperature range from –50 °C to 1050 °C, the sensor delivers response times down to 6 ms, enabling precise monitoring of rapidly changing thermal processes. Operating in the 8–14 µm spectral range, the LTfast model is ideal for high-emissivity targets and lower temperature applications such as plastics processing, automation systems, and fast production lines. Its rugged sensing head withstands ambient tem- peratures up to 125 °C without cooling, while flexible analog and digital interfaces allow seamless integration into modern automation environments.

Flexible Platform with Industrial Connectivity
All new CTi models follow Optris’ proven two-piece design with separated electronics, integrated display, and easily accessible programming keys. Extensive interface options including analog outputs, A built-in USB interface, which was not available in the previous CT series, RS485, Ethernet-based protocols, and industrial fieldbus systems ensure straightforward system integration and long-term scalability.  

“With the new CTi 1M, CTi 2M and CTi LTfast models, we are significantly expanding the flexibility of our CTi platform,” says Torsten Czech, Head of Marketing at Optris. “Customers benefit from optimized wavelength selection, extremely fast response times, and a compact, robust design that enables reliable temperature measurement across a wide range of industrial applications.”
