Modern manufacturing processes require minimal human intervention and a high degree of automation to meet industry demands. Due to variability in industrial process conditions, custom systems are often sought for these applications. These systems must be compact, economical, and capable of operating under different environmental conditions. This work presents the development, fabrication, testing, and validation of a low cost small scale temperature data-logger used as a monitoring system for automated applications. The proposed system is battery powered and packaged in a manner able to operate in temperatures up to 100oC, with exposure to chemicals such as Isopropyl Alcohol, Propylene Glycol, and De-Ionized water for a period of 2 hours with accuracy of ±0.5oC. The hydration process used for contact lens manufacturing is proposed as a target application for the developed system.

The developed system was bench top tested and validated using a convection oven and the three chemicals Propylene Glycol, Isopropyl Alcohol, and De-ionized Water. In addition, the system was tested “in-situ” in the hydration lines of a contact lens manufacturing process. The development process illustrated in this work including the system design, fabrication, and testing can be used as a base to develop the “best fit” monitoring system for multiple other applications.
