[Case Study] Verification of Stirring Operation for Pharmaceutical Mixing Machine

Installed a magnetic proximity switch and achieved zero troubles! Here’s a case study demonstrating reliable monitoring!

We have been using a stirrer for drug formulation, and until now, we managed the mixing process by timing it with the stirrer's button. Although we adjust the stirring time based on seasonal conditions, managing it by time means that any malfunction could lead to insufficient mixing and result in product defects. There have been requests such as "I want to monitor whether the stirrer is definitely running" and "I want to manage the stirrer's rotation speed and shorten the changeover time." We installed the magnetic proximity switch "DW-100" manufactured by Makome Research Institute on the stirrer, placing the "DW-100" next to the stirrer shaft, and affixing the magnetic bodies "SMG-100N" and "SMG-100S" around the shaft. As a result of this improvement, by installing the "DW-100," we can now manage the count of the stirrer, making the changeover process smoother. *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Overview of the Case (Partial)】 ■Trouble Case (Requests) - I want to monitor whether the stirrer is definitely running. - I want to manage the stirrer's rotation speed and reduce the changeover time. - The photoelectric tube cannot be used due to the influence of chemicals and dust. - I do not want the aging of motors, etc., to affect the stirring process. ■Trouble Situation and Loss - In the past, there was a stirrer trouble that required lot-out and full inspection. - Loss amount: 6,589,000 yen. ■Points of Improvement and Expected Customer Benefits - The DW-100 detects without contact and can sense up to a detection distance of 40mm. - Like the DW-350, the DW-100 can detect N and S poles and provide independent output, reliably counting the rotation speed. - The case is designed with a protective structure of "IP67" through sealing molding, allowing use in environments with chemicals (depending on the components) and dust. ■Effects and Benefits of Improvement - By installing the DW-100, management of the stirrer's count can be achieved, and changeovers have become smoother. *For more details, please refer to the PDF document or feel free to contact us.
