The Optris CT P7 pyrometer is specifically designed for non-contact temperature measurement of thin plastic materials, offering a wide range from 0 °C to 710 °C. The infrared sensor specialized spectral region of 7.9 µm ensures precise temperature measurements of thin plastic materials. This innovative pyrometer provides accurate readings within its temperature range and features a measuring head that can withstand temperatures up to 85 °C without additional cooling.
With a measuring wavelength of 7.9 µm, the Optris CT P7 is particularly well-suited for temperature control during the production of thin plastic foils. The pyrometers machine sensing time of 150 ms ensures rapid response, enhancing efficiency in various industrial processes.
Emissivity, a crucial factor in temperature measurement accuracy, is carefully considered in the design of the Optris CT P7. Plastics thicker than 0.4 mm and pigmented films can be easily measured in the long-wave IR spectral range (8-14 µm) with high emissivity of ≥ 0.9. However, very thin plastic films are transparent in this spectral range. To address this, the CT P7 utilizes material-specific absorption bands in the IR spectrum, employing narrowband sensitive IR sensors for precise temperature measurement. For example, materials like Fluoroplastic (FEP), Polyimide (PI), Acrylic (PMMA), Polycarbonate (PC), Polyester (PET), and Polyvinyl chloride (PVC or Vinyl) exhibit IR opaqueness at 7.9 µm and are therefore easy to measure with the Optris CT P7.
The Optris CT P7 offers a range of features to meet industrial needs. The infrared thermometers separate electronics box includes easily accessible programming buttons and an illuminated LCD, ensuring user-friendly operation.
The Optris CT P7 series infrared sensor prioritizes adaptability, featuring an electronics box with 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, RS232 interfaces, relay outputs (2 x optically isolated), Profibus DP, ProfiNet, and Ethernet, Ethernet/IP.
