A system and method for monitoring heat exchanger tube health without requiring the heat exchanger system to be shut down and disassembled and without operator intervention. At least one wireless sensor ball (WSB) assembly is positioned in the heat exchanger system. The heat exchanger system includes an ultrasonic acoustic receiver array mounted therewithin. WSB assembly information is gathered regarding status, operating condition, health, efficiency of the piping system, and/or, piping system health trends.

A method for automatic and sterile-container-specific detection of sterilization cycles carried out by a sterile container, and a system for carrying out the method. A temperature acting on the sterile container is detected using a temperature measurement device associated with the sterile container. A temperature measurement device detects the temperature at fixed first time intervals. Detected temperature values are stored in a memory once a predetermined first limit temperature has been exceeded. Storage of detected temperature values is suspended once a predetermined second limit temperature has been undershot or after a predetermined duration has elapsed after the first limit temperature has been exceeded. The stored temperature values are compared with reference temperature values. A deviation between the temperature values and the reference temperature values is determined. A counter and/or a display device are/is actuated when a deviation is determined within a predetermined tolerance range.

Temperature measurements are critical in gas turbine engine design but difficult to obtain due to the extreme environment. Temperature indicating paints (thermal paints) have been used for decades to map maximum temperature fields on superalloy components but have numerous weaknesses. Disclosed herein are novel glass ceramic thermal paints that undergo viscous flow sintering to indicate temperatures up to 1000 C., with high resolution (5 C.), by an optical transition. Disclosed paint formulations are designed to adhere to Nickel-based superalloys or SiCSiC ceramic matrix composites (CMC) by closely matching coefficients of thermal expansion and may function for times above 60 hours. By utilizing automation and a UV:VIS spectrometer, quantitative temperature maps can be generated for easy comparison to theoretical models. A transient sintering energy model is disclosed to recover full thermal history information.

Methods and systems implement wireless, batteryless sensors which electronically store measurements to a data logger, the data logger being configurable to compute measurements based on the frequency measurements and electronically feed back to electronic controllers of systems and apparatuses which computationally monitor temperature. A data logger can be configured to write and transmit temperature measurements to any electronic controller having a data communication interface. The temperature sensors, in conjunction with the data logger, can provide any heating system, including chamber heating systems such as dry-heat and steam sterilizers, with article-localized temperature measurement feedback, to improve the accuracy of real-time temperature monitoring and/or control. Electronic controllers can be configured to output sufficient heat, then terminate a heat control cycle or a steam sterilization cycle, after having exposed to heat some number of articles to a desired extent as specified by a cumulative heating specification or a target temperature-over-time profile.
