CT G5

The Optris CT G5 pyrometer is expertly designed for precise temperature measurement in glass-related applications. The pyrometers two-piece sensor design, which includes a separate electronic box with programming keys and a display, ensures user-friendly operation and accurate temperature readings across a range of 100 °C to 1650 °C. Ideal for vehicle and flat glass manufacturing processes, the CT G5 delivers reliable and accurate temperature measurements to meet diverse industrial needs.

In non-contact stationary infrared temperature measurement, ensuring accuracy requires careful consideration of emissivity, which depends on material properties, surface characteristics, wavelength, measuring angle, and the measuring setup. For example, uncoated glass typically exhibits an emissivity of 0.85 in the longwave range (8 μm – 14 μm). However, in high-temperature processes such as glass production, using wavelengths of 5.0 μm or 7.9 μm is preferred due to their higher emissivity values (≥0.95) in those spectral ranges. Wavelength selection is crucial for effectively measuring the glass surface and deeper layers, with 1.0 μm, 2.2 μm, or 3.9 μm suitable for deeper layers, and 5.0 μm recommended for surface measurements. For lower temperatures, wavelengths between 8 μm and 14 μm and an emissivity of 0.85 help mitigate reflection effects.

The Optris CT G5, with its specialized spectral range of 5.0 µm, is a versatile tool for measuring glass temperatures in various industrial processes. The infrared thermometer is suitable for container glass production, vehicle glass manufacturing, and solar cell production, delivering reliable temperature data. The compact stainless steel measuring head allows for versatile installations, including multi-spot configurations such as line scanning, even in limited spaces. The measuring head operates in ambient temperatures of up to 85 °C without additional cooling, making it robust and adaptable.

A key attribute of the Optris CT G5 is its precise non-contact temperature measurement facilitated by separate electronics. The electronic box offers a wide array of analog and digital outputs, including 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, thermocouple (type K or J), USB, RS485, and RS232 interfaces, as well as relay outputs (2 x optically isolated), Profibus DP, ProfiNet, and Ethernet, Ethernet/IP.

To further enhance the functionality of the infrared sensor, various optional accessories are available, catering to diverse industrial needs. The mounting fork ensures secure and stable installation for continuous temperature monitoring. The sighting tube enhances targeting precision and accuracy in specific applications. The close-focus lens allows detailed temperature measurements on small or distant objects, and the air purge accessory protects the temperature sensor from contaminants to maintain the optical path in harsh environments. Additionally, the cooling jackets optimize performance in elevated temperature conditions, ensuring consistent and accurate readings.

These optional accessories significantly enhance the versatility of the Optris CT G5 series, providing tailored solutions for various industrial scenarios.

In summary, the Optris CT G5 series pyrometer combines precision, adaptability, and durability to facilitate non-contact temperature measurements in glass-related applications. Whether capturing rapid manufacturing processes or operating in challenging conditions, the IR pyrometer is a reliable and efficient solution for diverse industrial needs.
