CT LT

The Optris CT LT series pyrometers are equipped with one of the world’s smallest infrared sensing heads, boasting a high optical resolution of up to 22:1. Utilizing a thermopile as a detector and operating within a spectral bandwidth of 8-14µm, these pyrometers excel in infrared measurement of high-emissivity targets, even at low object temperatures, in fixed installed situations.

Featuring a separate control box offering high variability with selectable analog outputs and several digital interfaces, the CT LT sensors present unique advantages for installation in applications with high surrounding temperatures. Their robust and ambitious design allows the sensing heads to withstand temperatures up to 180 °C without additional cooling, making these pyrometers ideal for high-temperature environments.

The Optris CT LT series sets the industrial standard for non-contact temperature measurement, prioritizing precision and speed. With a two-piece design incorporating one of the smallest infrared sensors globally, a commendable optical resolution of up to 22:1, and a rapid exposure time of down to 150 ms, these pyrometers are optimized for efficient monitoring of fast-paced manufacturing processes across industries. Their wide temperature range from -50 °C to 975 °C suits non-reflecting objects.

Exceptional temperature resistance characterizes the pyrometers‘ capabilities, enabling seamless operation in ambient temperatures up to 180 °C without supplementary cooling. Their distinctive thermal shock-resistant design ensures repeatability with ambient temperature changes, meeting high-quality standards engineered and manufactured in Germany.

Designed for fixed installation, the Optris CT LT series provides a permanent and reliable solution for continuous temperature monitoring. Its precise non-contact temperature measurement facilitated by separate electronics, with easily accessible programming keys and an LCD interface, ensures stability and accuracy over extended periods in varied industrial settings.

The adaptability of the Optris CT LT series is further emphasized by the range of analog and digital outputs provided by the electronics box, including 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, thermocouple (type K or J), USB, RS485, RS232 interfaces, relay outputs (2 x optically isolated), Profibus DP, ProfiNet, and Ethernet, Ethernet/IP. This adaptability facilitates seamless integration into machinery, enhancing utility across various applications.

Optional accessories tailored to diverse industrial needs further enhance the functionality of the infrared sensor. The mounting fork ensures secure and stable installation, while the sighting tube improves targeting and accuracy. The close-focus lens enables detailed temperature measurements on small or distant objects, and the air purge accessory safeguards the temperature sensor from contaminants in harsh environments. Cooling jackets optimize performance in elevated temperature conditions, ensuring consistent and accurate readings.

In summary, the Optris CT LT series pyrometers combine precision, adaptability, and durability to facilitate non-contact temperature measurements across diverse industrial applications, offering reliability and efficiency in challenging conditions.
