A standout feature of the CTlaser 3M is it’s incredibly short response time of just 1 millisecond, enabling the detection of fast-paced processes with exceptional accuracy. Additionally, the pyrometers capability to measure reliably and precisely on the smallest measuring fields, as tiny as 0.7 mm, underscores its high performance in capturing accurate temperature data even in challenging conditions. This precision is particularly vital in industries where slight temperature deviations can significantly impact product quality and process efficiency.
The CTlaser 3M’s short-wavelength spectral sensitivity minimizes measurement deviations resulting from changing emissivity, ensuring consistency and reliability in temperature readings, especially with materials prone to emissivity fluctuations. Equipped with an extended InGaAs detector operating at a wavelength of 2.3 μm, this advanced detector guarantees accurate temperature measurements across various materials, including metals, secondary metal processing, metal oxides, and ceramic materials.
The CTlaser 3M series offers different models with varying temperature ranges to cater to diverse industrial needs. The 3ML model covers temperatures from 50 °C to 800 °C, suitable for lower temperature measurements, while the 3MH model spans temperatures from 385 °C to 1600 °C, optimized for higher temperature requirements. The 3MH1 model extends the range from 490 °C to 1800 °C, providing engineers with flexibility to select the instrument that best suits their specific temperature measurement requirements.
Another notable feature of the CTlaser 3M series is its double laser aiming marks, providing precise aiming support and enhancing accuracy in temperature monitoring. Unlike conventional IR thermometers equipped with single lasers, the CTlaser 3M series utilizes an innovative double laser sighting system, ensuring unparalleled accuracy and confidence in temperature measurements.
The CTlaser 3M offers greater flexibility in installation and usage, with a wide range of analog and digital outputs, , including 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, USB, RS485, RS232 interface, relay outputs (2 x optically isolated), Profibus DP, Modbus RTU, Modbus TCP, Profinet, and EtherNet/IP. This extensive range of output options ensures seamless integration into various industrial processes and monitoring systems, even in demanding environments with ambient temperatures up to 85 °C.
Enhanced with Optris accessories like air purging and mounting flanges, the CTlaser 3M pyrometer can be adapted to various manufacturing and process applications, expanding the infrared thermometers capabilities and ensuring compatibility with different environments and operating conditions. Calibration in Germany to meet regulation standards such as PTB or NIST, along with customization options like different cable sizes, further enhance the instrument’s accuracy, reliability, and flexibility to meet specific user requirements.
Optris provides comprehensive support for the CTlaser 3M series, including consultation on industrial applications and after-sales assistance, ensuring users can maximize the performance and utility of their pyrometers. With its precision, versatility, and reliability, the CTlaser 3M series sets a new standard for excellence in infrared thermometry, offering valuable temperature measurement solutions for diverse industrial environments.
