Low emissivity/High transparency? Not a problem: Choose the optimal devices for transparent foil
Understanding emissivity, transparency and influence of spectral sensitivity is the key to create a high-quality product in the plastic industry, especially when working with transparent foil. Since this product has different infrared properties, selecting the appropriate measurement device is critical to ensure temperature readings aren’t affected by external influences.
Within our proven product series, we have devices/models designed for the measurement of highly transparent films. In the case of transparent foil monitoring, we can recommend our MP Line Scanner and Thermalert 4.0, which are able to deal with the unique challenges caused by lower emissivity and higher transparency.
These solutions support various applications, including:
- Blown Film Extrusion
- Sheet Extrusion
- Laminating and Embossing
- Thermoforming
- Extrusion coating
Our Thermalert 4.0 Series stands out with its integrated intelligent system, remotely addressable 2-wire sensors, with wide temperature ranges from -40 °C to 2300 °C, delivering precise and reproducible temperature readings on hot/cold, moving, and heavy surfaces. Complementing this, the MP300 Line Scanner offers convenient monitoring product widths, providing up to 256 temperature points per scan at 48 lines per second, with a wide 90-degree scanning angle.
For example, in blown film extrusion, Our Thermalert 4.0 Series accurately monitors temperatures at critical points such as the nozzle and folding frame, while the MP300 Line Scanner covers the entire length of the blown film. Similarly, in sheet extrusion, you can benefit from continuous temperature monitoring with the MP300 Line Scanner positioned before the draw rollers, enabling real-time detection of anomalies like hot spots or irregularities in the sheet. This capability allows for immediate adjustments to heating and cooling settings, enhancing product consistency and plant performance.
