The IR sensor offers various focal points for versatility and guarantees outstanding accuracy and repeatability for non-contact temperature measurements.
The Optris CTlaser LT series is renowned for its high standard in non-contact temperature measurement, delivering precise accuracy and a wide temperature range. Characterized by a two-piece design, these pyrometers integrate an infrared sensor with a high optical resolution of 75:1. Their non-contact capability makes them ideal for monitoring industrial processes where physical contact with the object is impractical. These pyrometers are typically used in fixed installations, ensuring consistent and precise temperature measurements.
The CTlaser LT series offers a temperature range from -50 °C to 975 °C, optimized for non-reflective surfaces, showcasing remarkable versatility in temperature measurement applications with a response time of up to 120 ms. These pyrometers are primarily utilized in industrial settings, research, and development, where small measurement spots are critical for precise temperature assessment. They provide various focus versions to accommodate diverse applications, including CF1: 0.9 mm at 70 mm, CF2: 1.9 mm at 150 mm, and CF3: 2.75 mm at 200mm.
The series ensures exceptional temperature measurement accuracy, with a system accuracy of ±1.0% or ±1.0 °C, guaranteeing reliable and consistent readings. The infrared sensors repeatability stands at ±0.5% or ±0.5 °C, further reinforcing the reliability of the measurements.
A standout feature of the CTlaser LT series is its double laser aiming marks, which pinpoint the exact location of the measured spot and offer valuable insights into the spot size. This visual aid enhances accuracy in temperature monitoring, facilitates precise alignment, and minimizes measurement errors. The series employs an innovative double laser sighting system, unlike conventional IR thermometers with single lasers that only mark the center of the spot. The two laser beams follow the infrared optical path to indicate the spot’s position at any distance.
Each CTlaser LT pyrometer features a two-piece design, comprising a separate electronics box that delivers advanced signal processing capabilities. The online pyrometer offers a wide array of analog and digital outputs, including 0/4–20 mA, 0–5 V, 0–10 V, USB, Ethernet, RS485, RS232 interface, relay outputs (2 x optically isolated), Profibus DP, Modbus TCP, ProfiNet, and Ethernet/IP. This versatility facilitates seamless integration into many industrial processes and monitoring systems.
Enhanced with Optris accessories such as air purging and mounting flanges, the CTlaser LT pyrometer is designed for integration into various manufacturing and process applications. Manufactured and calibrated in Germany, these pyrometers adhere to government standards such as PTB or NIST. Customization options, such as different cable sizes, are available to meet specific requirements. Optris provides comprehensive support, including consultation on industrial applications and post-sales assistance, ensuring optimal performance and user satisfaction.
