CS LT Compact Single-piece Industrial Infrared Pyrometer

The infrared pyrometer optris CS LT is perfectly suited for temperature measurement in small and narrow environments. The robust measuring heads have been developed for non-contact measurement of temperature from -50 °C to 1,030 °C and can be employed in ambient temperatures of up to 80 °C without additional cooling. The inexpensive pyrometers are designed for serial integration into machinery equipment and industrial manufacturing environments.

The CS LT Pyrometer is an advanced yet budget-friendly infrared sensor, designed to offer dependable and cost-effective temperature measurements. The pyrometer delivers precise, non-contact temperature measurements for a wide range of industrial applications. Equipped with a thermopile detector, the CS LT Pyrometer operates within a spectral bandwidth of 8-14µm, making the infrared sensor an excellent choice for measuring high-emissivity targets, even at low temperatures.
The Optris CL LT Pyrometer is versatile and widely used across numerous applications, and is commonly employed in the thermoforming process of foil, plastic processing, machine condition monitoring, and overheating equipment alarms. Additionally, this infrared sensor serves as an invaluable tool for preventive electrical maintenance, helping to detect potential outages.

With a high distance-to-spot size ratio of 15:1, the CS LT Pyrometer ensures accurate measurements of small spot sizes from a distance, covering a temperature range from -50 °C to 1030 °C. These cost-effective pyrometers are ideal for machine builders and manufacturing environments, supporting analog voltage, digital alarms, serial communication over RS232, and thermocouple (type K) outputs, seamlessly integrating temperature data into control systems.
Due to its low pricing and ease of use, the CS LT Pyrometer has become a popular alternative to traditional contact-based temperature sensing applications.

The CS LT Pyrometer stands out due to its low pricing and ease of use, making the infrared sensor a popular alternative to traditional contact-based temperature sensors. The unique thermal shock-resistant design ensures reliable measurements even in challenging conditions, unlike other low-budget sensors. The robust stainless steel measuring head, with an M12x1 thread, is easy to install in tight hot spaces without extra cooling, up to 80 °C. The compact sensing head measures just 85 mm in length and 12 mm in diameter. Additionally, the LED lighting on the back of the sensor serves as a visual alarm or error indicator, enhancing its functionality and reliability.
Configuration, fine-tuning settings, and the setup of the sensor are supported through the optional USB kit and the Compact Connect software, available for free download. Additionally, the USB kit and software offer convenient recording of temperature measurements over time. For quick commissioning, temperature measurements and changes over time can also be displayed on the Optris IR mobile app, available for free on Google Play.
The CS LT pyrometer can also be equipped with Optris accessories, including air purging, a laser sighting tool, mounting flanges, and close-focus optics. These accessories enable temperature measurements of small spot-size targets from a close distance.

These pyrometers are designed and manufactured in Germany, carefully calibrated to government standards such as PTB or NIST. For large-quantity OEM customers, customization options, such as different cable sizes, are available. As with all Optris products, application engineers are on hand to discuss industrial applications and provide after-sales support.
