Precision sensor manufacturer Micro-Epsilon’s thermoMETER CTP-3 enables the non-contact measurement of thin PP, PE and PS film. The infrared temperature sensor operates at a wavelength of 3.43-microns, which is claimed to be particularly suitable for these types of film.
Plastics films with a thickness of less than 1mm are normally transparent to standard infrared sensors; however this machine measures in a narrow spectral range, where the IR transmission is blocked for these materials.
The temperature range extends from 50 to 400 deg C and the pyrometer is said to provide stable measurements in ambient temperatures up to 75 deg C. It is available with either analogue or digital outputs.
