New infrared pyrometer measures temperature of thin plastic film

Normally plastic films with a thickness less than 1mm are transparent to standard IR temperature sensors. However, the thermoMETER CTP-3 pyrometer measures in a narrow spectral range of 3.43um where the IR transmission is blocked for these materials. This enables the temperature of polypropylene, polyethylene and polystyrene film to be measured reliably. The addition of the CTP-3 to the thermoMETER range of pyrometers means the company can offer products for non-contact temperature measurement on almost all materials.

The measurement range of the thermoMETER CTP-3 extends from 50degC to 400degC and stable measurement values are obtained in ambient temperatures up to 75degC. The pyrometer is available with either analogue or digital outputs.

The wavelength of 3.43um at which the thermoMETER CTP-3 operates is well suited to polypropylene, polyethylene and polystyrene film. With other film types such as polyethersulfone or polyurethane, the thermoMETER CTP-7 can be used, as its spectral range at 7.9um is adapted to suit these materials.

High accuracy and resolution are key characteristics of all thermoMETER sensors. Micro-Epsilon says that its infrared sensors are particularly useful for temperature-critical applications where reliable measurements are essential.
