Optris CTi LT – Compact, precise, robust
The pyrometers of the Optris CTi LT series set new standards in non-contact temperature measurement – with one of the world’s smallest infrared measuring heads, a high optical resolution of up to 22:1, and a wide temperature range from -50°C to 1050°C. Their specially tuned spectral range of 8–14µm makes them ideal for measurements on non-reflective objects with high emissivity – even at low temperatures.
The robust design allows for use in environments with temperatures up to 180°C – without the need for additional cooling. Thanks to the thermal shock-resistant construction, measurement results remain consistent and reproducible even under fluctuating ambient conditions.
The separation of the measuring head and electronics unit ensures high installation flexibility – even in tight spaces. The electronics offer analog output signals (0/4–20 mA, 0–5 V, 0–10 V, Type K thermocouple) as well as digital interfaces such as USB, RS232, RS485, Profibus DP, Profinet, Ethernet TCP/IP, and Ethernet/IP. Two galvanically isolated relay outputs enable easy process integration.
With a response time of only 115 ms (90% energy), the CTi LT is ideal for monitoring dynamic manufacturing processes. Optional accessories – such as a mounting fork, target optics, close-focus lens, air purge, and cooling housing – further expand the application possibilities and ensure protection and precision in demanding environments.
Made in Germany, the CTi LT series stands for the highest quality, durability, and depth of integration. Whether in plastics processing, the food industry, electronics manufacturing, or high-temperature processes – this pyrometer is the reliable solution for precise and continuous temperature monitoring.
