[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, the mixing conditions have been managed by timing with the stirrer's button. Although we change the stirring time based on seasonal conditions, managing it by time means that any malfunction can lead to insufficient stirring 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" made by Makome Research Institute on the stirrer, placing the "DW-100" next to the stirrer shaft, and attaching the magnetic bodies "SMG-100N" and "SMG-100S" half a turn each on the shaft. As a result of this improvement, by installing the "DW-100," we can manage the count of the stirrer, making the changeover 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 shorten 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 Losses - In the past, there was one stirrer trouble incident that required lot-out and full inspection. - Loss amount: 6,589,000 yen. ■Points of Improvement and Expected Customer Benefits - The DW-100 detects at a distance of up to 40mm without contact. - Similar to the DW-350, the DW-100 can detect N and S poles and provide independent output, reliably counting the rotation speed. - The case is protected with a sealing structure rated "IP67," 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.
