1. Vibra*Metrics, Inc.'s proposed innovation is to eliminate the two major temperature-related shortcomings of accelerometers by designing a vibration sensor with internal conditioning that operates to 350øC (well above the current 200øC). Processes defined in this effort are applicable to many types of sensors. 2. The objectives are: a) to obtain and attach the SiC impedance converter (FET) inside the vibration sensor, b) to design the sensor components for 350øC, c) to characterize the performance of the electronics and crystal separately and potentially as a finished assembly. 3. The effort proposed is to use the Advanced Tactical Fighter accelerometer design engineer (Pl) to obtain the SiC electronics from one of the two domestic sources. He will design the sensor components to withstand temperatures up to 350øC. The Pl will attempt to assemble and characterize at least one prototype unit. This will require the definition of unique assembly procedures. 4. Based on VMI's experience in high temperature accelerometers, VMI expects to fully accomplish their objectives. 5. NASA applications include the ability to monitor dynamic conditions in vehicle propulsion systems, engine compartments, skin structure during re-entry, and furnace experiments. This relates directly to safety critical and mission critical controls, and to system reliability. Commercial applications in markets VMI currently service include nuclear power plants, stationary engines, the processing and petro-chemical industries, downhole drilling, and others accelerometers, low impedance accelerometers, high temperature electronics, and silicon carbide.
