TEMPERATURE MEASUREMENT

Temperature Controllers Embrace the Era of AI Information provided by Omron

• Bringing sensors closer to the sealing surface – thanks to spe- cial temperature sensor models for faster detection • Adopting special algorithms (automatic filter adjustment func- tion) built-in E5_D, specifically developed to suppress temper- ature variations. The result is a better sealing quality of the packages Temperature variations in moulding machines minimised by a new algorithm On a water-cooled extrusion moulding machine, increasing the speed often leads to temperature variations due to various fac- tors such as the material compound and cooling water. For the human operator this means repeatedly making valve adjustments

Omron has introduced their E5_D series − the next generation of controllers built on the successful E5_C platform. It is designed to achieve optimal and automatic temperature control without hu- man intervention. Omron’s E5_C series substantially raised the bar for temperature control in the past five years thanks to its user-friendliness, high precision and highly reliable control. Now, the E5_D series − the next generation of controllers built on the successful E5_C plat- form − is designed to achieve optimal and automatic temperature control without human intervention. In fact, from now on all typical adjustments made in the field by experts are automated using Arti- ficial Intelligence (A.I.). The E5_D is based on the E5_C platform so the basic features are the same (50 msec control period, universal inputs measurements Thermocouples/Pt100/linear, and more) but with a draw-out structure to make maintenance even easier. Adaptive control algorithm With standard temperature controllers, not only do you need a long time to define initial start-up PID settings, but it is also really challenging to make the optimal adjustments without having many years of experience in this area. That is why Omron developed the E5_D Series with ‘adaptive control technology’. This automatically detects changes in the process under control and adapts the PID accordingly. The result? Perfectly fine-tuned PID algorithm and ul- tra-stable temperature control.

to stabilise the quality. However, it is really diffi- cult to achieve high speed production while also maintaining the quality. Not any more with the E5 D. The water-cooling output adjustment function suppresses the temperature variations to a minimum and raises the production capac- ity while maintaining quality.

Causes of temperature variations on production lines.

Perfect sealing temperature control for packaging machines On a conventional sealing machine temperature sensors can of- ten be located too far away from the sealing surface of the heat- ing bar. This causes a difference between the temperature of the sealing surface and the temperature that was actually being con- trolled. This temperature difference and resulting sealing failures, increase as the packaging speed increases and also in correlation with thinner packaging materials. Thanks to the E5_D series, this issue is solved with the following approach:
