Broken tool detection control unit

for agitators

This monitoring system to detect failure of static-dynamic mixing systems leads to greater production security. The system consists of: • a special mixer element • a hall sensor • monitoring software in the metering computer and corresponding software on the external monitoring unit Any failure of the mixing system will automatically be instantly detected, allowing the system to be shut down immediately, automatically or manually. Optionally, every static-dynamic mixing system can be assembled with mixer element monitoring. The situation Metering and mixing systems are often fitted with a static-dynamic mixer when processing materials that have certain exceptional features, such as: • extreme metering ratios • large differences in viscosity between the components • Greater than normal mixing energy requirements Until now, it has not been possible to reliably monitor the rotation of the mixer element inorder to confirm that it is rotating at the correct speed, or even to establish if it has failed completely, which might be the case should the mixed material remain in the mixer beyond its pot life due to an extended interruption to production. Should production continue after the mixer has ceased to function, the resulting components would become expensive rejects.
