The controllability of stirring processes - Part 2: How to control?

In Part 1 of „The controllability of stirring processes“, we looked at the question of why stirring processes need to be controlled at all. Not read it yet? You can find the first part here.

In Part 2, we would like to show you which control options are available and when which option can be used. Particular attention should be paid to their use in ATEX zones. You can get an overview of the ATEX zones in advance at here provide.

Speed display

This speed display is the simplest, most uncomplicated and certainly the cheapest way of keeping an eye on the mixing process and controlling it accordingly.

While you can read the exact actual speed on the speed display, you can regulate the speed via the needle valve on the motor until you have reached your optimum speed. If conditions in the tank change that affect the set speed (e.g. higher Viscosities or higher fill levels), you can easily readjust. That's it!

Please note that this speed indicator is not suitable for use in ATEX zones.

Speed display ATEX Zone 2

This stand-alone speed indicator is suitable for applications in ATEX zones. It can be used in ATEX zone 2. This is made possible by placing the stand-alone device slightly further away from the stirring application. The stand-alone device can be easily attached to suitable surfaces using the base.

The associated power box is located outside the ATEX area.

Speed control non-ATEX and ATEX Zone 1

This device allows you to set the speed to a specific value in advance. If the conditions in the container change, e.g. due to a change in viscosity or fill level, the control system automatically adjusts the speed to the preset value. This saves you manual adjustments and guarantees the same stirring quality at all times.

This speed control is available in two versions: non-ATEX and certified for ATEX Zone 1.

Here we have presented the three options for simple process control for different ATEX zones.

Your application becomes really smart with comprehensive intelligent control. Control and regulate your speed conveniently via touchscreen. With up to 100 presettable recipes, you can define the speed and mixing time for different applications in advance. Then activate your programs easily by touch. This allows you to specify entire mixing cycles with varying speeds and mixing times. No more manual settings, no more waiting.

In our Part 3 of „The controllability of stirring processes“, we will soon be presenting this smart type of control in detail. Don't feel like waiting? Then simply contact our experts for a non-binding consultation.
