Acceleration sensitivity as a function of temperature

Abstract

Acceleration sensitivity measurements on quartz resonators have been made as a function of temperature from -50 degrees C to +100 degrees C. 100 MHz and 10 MHz resonators were measured. Several cuts were tested including AT, SC, and IT. Acceleration sensitivity is characterized by the vector Gamma . The variation in Gamma with temperature is important in applications where Gamma is specified over a wide temperature range or when the vectorial properties of Gamma are being utilized to minimize the acceleration sensitivity in a particular direction. Results indicate that the direction and magnitude of the acceleration sensitivity vector Gamma can vary dramatically with temperature. The variations are greater at high frequencies than at low frequencies. Likewise, the variations are greater in resonators with small Gamma than in those with larger Gamma .<>
