Technical buyers will find that Raytek fixed-mount sensors in the CM series offer a 13:1 distance-to-spot ratio, adjustable emissivity from 0.10 to 1.10, and 24 V DC input with 5 V DC maximum output. Enclosure ratings include IP65 and NEMA 4, making them suitable for washdown and dusty environments. The sensors feature a 3/4"-16 UNF thread for mounting, and cable lengths vary by model, with options such as 3.2 ft and 10 ft. Accessories such as air purge collars (XXXCIAP, XXXCMACAP) direct compressed air across the lens to prevent dust, smoke, and debris buildup, maintaining measurement accuracy in dirty conditions. Protective silicon windows (XXXCMACPW) shield sensor optics from dust, debris, and thermal exposure while maintaining infrared transmission. Mounting nuts (XXXCMACMN) secure sensor components during installation. These accessories are designed for compatibility with specific series, ensuring proper fit and function. 3G Electric supports the Raytek line by providing datasheets, technical specifications, and logistics coordination for global delivery. The company serves plant engineers, maintenance managers, and procurement specialists who require reliable temperature measurement solutions. With a focus on industrial applications, 3G Electric ensures that customers can access the right Raytek products for their specific needs, from individual sensors to complete accessory kits. The product range includes models such as RAYCMLTV3, RAYCMLTV, RAYCMLTK, and RAYCMLTK3, each with specific features and cable lengths. These sensors are designed for fixed installation and continuous operation, with CE and ISO 9001 standards referenced in some product documentation. By offering these products, 3G Electric enables effective non-contact temperature monitoring across a variety of industrial processes.

Frequently asked questions

Common questions about RAYTEK from 3G Electric.

What is the distance-to-spot ratio of Raytek CM series fixed-mount infrared temperature sensors?

Raytek CM series fixed-mount infrared temperature sensors, such as the RAYCMLTV3 and RAYCMLTK models, feature a 13:1 distance-to-spot ratio. This means that at a distance of 13 units from the target, the sensor measures a spot size of 1 unit. This ratio is suitable for many industrial applications where the target is relatively small or at a moderate distance. The adjustable emissivity range of 0.10 to 1.10 allows users to calibrate the sensor for different materials, ensuring accurate readings. The sensors operate on 24 V DC input and provide a 5 V DC maximum output, compatible with common control systems.

What is the purpose of the Raytek air purge collar for CI and CM series sensors?

The Raytek air purge collar, available for CI series (XXXCIAP) and CM series (XXXCMACAP), directs compressed air across the sensor lens to prevent dust, debris, and moisture buildup. This is critical in environments where contaminants can accumulate on the optics and degrade measurement accuracy. By maintaining a clean lens, the air purge collar helps ensure consistent infrared temperature readings. It is particularly useful in applications such as cement kilns, glass furnaces, and foundries, where airborne particles are common. The collar is designed for easy installation and compatibility with the respective sensor series.

What are the enclosure ratings for Raytek fixed-mount infrared temperature sensors?

Raytek fixed-mount infrared temperature sensors in the CM series are rated IP65 and NEMA 4. IP65 indicates protection against dust ingress and water jets from any direction, while NEMA 4 ratings cover similar environmental protection for indoor and outdoor use. These ratings make the sensors suitable for washdown areas, dusty industrial settings, and outdoor installations where exposure to moisture or particulates is a concern. The sensors also feature a 3/4"-16 UNF thread for secure mounting. Cable lengths vary by model, with options such as 3.2 ft and 10 ft to accommodate different installation distances.

What accessories are available for Raytek CM series infrared temperature sensors?

Accessories for Raytek CM series infrared temperature sensors include mounting nuts (XXXCMACMN), air purge collars (XXXCMACAP), and protective silicon windows (XXXCMACPW). The mounting nut secures the sensor during installation. The air purge collar keeps the lens clean by directing compressed air across it. The protective silicon window shields the sensor optics from dust, debris, and thermal exposure while maintaining infrared transmission. These accessories are designed specifically for the CM series to ensure proper fit and function. They help extend sensor life and maintain measurement accuracy in challenging industrial environments.

What is the emissivity range of Raytek fixed-mount infrared temperature sensors?

Raytek fixed-mount infrared temperature sensors, such as the RAYCMLTV3 and RAYCMLTK models, have an adjustable emissivity range from 0.10 to 1.10. Emissivity is a measure of a material's ability to emit infrared energy, and different materials have different emissivity values. The adjustable range allows users to set the sensor for accurate readings on a variety of target materials, from highly reflective metals to dark, non-reflective surfaces. This flexibility is essential for applications where the target material may change or where precise temperature measurement is required. The sensors also offer a repeatability specification, ensuring consistent performance over time.

What are the input and output specifications for Raytek CM series sensors?

Raytek CM series fixed-mount infrared temperature sensors operate on a 24 V DC input and provide a 5 V DC maximum output. This output can be connected to PLCs, controllers, or data loggers for process monitoring and control. The sensors are designed for continuous operation and feature a 3/4"-16 UNF thread for mounting. Cable lengths include 3.2 ft and 10 ft options. The sensors meet CE and ISO 9001 standards as indicated in product documentation. These specifications make them suitable for integration into existing industrial control systems.
