Abstract: A system and method allow a sensor device that is used in a process stream to be efficiently calibrated and monitored as to its operating condition. The sensor device is a measuring probe with a sensor portion, a memory device and an electrical input/output port, arranged so the memory device is in communication with both the sensor portion and the input/output port. The sensor device may be connected through an electrical connector to either a first external source, such as a personal computer having an input/output port, remote from the process stream, or a second external source, such as a transmitter, proximate to the process stream. Operating software is accessible to at least the first external source for monitoring and calibrating. Database software is accessible to each of the external sources, for storing data on every measuring probe used in the system.

Abstract: A sensor unit for attachment to a container such as a bag or other vessel used to retain material includes a clamping mechanism for attaching the sensor unit to the container. The clamping mechanism may be configured to break or provide an indication that the connection between the sensor and container has broken that is visually detectable before a leak of material occurs or is detectable by a person visually monitoring the container or sensor. Such an indication can also indicate that the sensor was previously used and should not be used again for single use applications. Such a visual indicator is separate and different from seeing an actual leak and permits an event that may desterilize material within the container or lead to other problems to be corrected prior to use of a single use reaction system.
