Flight Testing Calibration Transfer Standards Metrology Windtunnel/Turbine Test Oceanography Series 960 QuartzonixTM Pressure Standards are designed for use as a precision pressure transducer where the highest levels of traceable accuracy and stability are required. QuartzonixTM pressure standards use a patented monolithic quartz resonator to achieve unparalleled accuracy and stability. Pressure is measured via a change in the resonant frequency of an oscillating quartz beam by pressureinduced stress. QuartzonixTM pressure standards produce an output frequency between 30 and 45 kHz and can achieve a pressure resolution of 0.0001% FS. The units provide conformance to a calibration curve of better than 0.01% FS and have long-term stability of 0.01% FS over a six month period. Precise thermal compensation is provided via an integrated quartz temperature sensor used to measure the operating temperature of the transducer. The low mass design of the sensing elements allows the transducer to be employed in applications which experience high acceleration, shock and vibrational loads.
