Process monitoring and control using battery-free multipoint wireless product condition (state) sensing

摘要

Equipment for monitoring aseptic manufacturing processes includes product condition (condition) sensors that are capable of making close proximity measurements of product conditions (conditions) such as temperature or humidity. Measurements are made using proximity spaced sensors arranged in a linear array on a single probe that can be used to take measurements at multiple levels within the product. Data from the sensor is transmitted to the data collection point via short-range wireless digital communication. Using sensors, they can be used to measure temperature and humidity at a single point. For example, if the sensor is used for pharmaceutical lyophilization, the position of the foremost sublimation may be calculated for each vial and the lyophilization process may be controlled using the data.
