Temperature measurement for high speed applications

Fast measurement. Small measuring spot. Favorable price.


Customer requests

The seals of crown caps are glued in place in a high-speed process up to 5,000 caps can pass through the corresponding system per minute. Induction heating activates the adhesive coating and the sealing compound can then be pressed on.

Uniform heating of the crown corks is essential to ensure that the seal is applied to the entire surface of the crown cork and a correct sealing of the bottles is possible later in the filling lines.

For this purpose, a high speed temperature measurement is necessary, which correctly determines the temperature on a small measuring spot.

Solution: High speed pyrometer from Optris

To measure the temperature correctly – and most importantly, quickly – Optris has developed the high speed pyrometer CTlaser 4M for ultra-fast manufacturing processes.

It can measure the temperature within just 90 μs.

In this application, the temperature of the crown corks is measured at the rim – so the uniform heating can be controlled.

• Acquisition time: 90 μs (90 %)
• System accuracy: ± (0,3 % TMess + 2 °C)
• Optical resolution (90 % energy): 30:1
• Protection class: IP 65 (NEMA-4)

Further advantages / Summary

The ultrafast CTlaser 4M is ideal for fast, high-volume production and packaging processes (e. g. PET preform temperature monitoring) and high-speed applications in the field of traffic safety (e. g.overheating detection on railroads).

It is the ideal pyrometer for high speed, low temperature measurements on non metallic and also metallic surfaces.
