Embodiment Construction

[0028] In some current systems a wireless sensor, such as a temperature sensor, is used as a single point monitoring probe within the product container bottle. These sensors may be induction-based sensing systems that are excited wirelessly to determine the resonant frequency as a function of temperature. Other layouts use thermocouples in communication with the data acquisition module. Due to the sensing technology and physical size of these sensors, it is generally feasible to use only a single sensor per sensing probe. Furthermore, inductance-based sensors operate based on the excitation of crystals within an electromagnetic field, and inductance-based sensors placed in close proximity tend to interfere with each other, hindering the use of multiple sensors per bottle.

[0029] Currently, wireless capacitive humidity sensors are used as single-point monitoring devices, typically in applications at or near room temperature, such as museums, printers, and greenhouses.

Abstract

An arrangement for monitoring aseptic manufacturing processes, including product status sensors capable of intensive measurements of product status such as temperature or humidity. This measurement is performed using dense sensors arranged in a linear array on a single probe, which can be used to measure at multiple levels within the product. Data from the sensors is communicated to the data collection point via short-range wireless digital communication. Sensors can be used to measure temperature and humidity at a single point. For example, when the sensor is used for freeze drying in pharmaceuticals, the position of the sublimation interface can be calculated for each bottle and this data can be used to control the freeze drying process.
