Abstract
The change of frequency with temperature of a quartz crystal plate 1.8×1.8×0.11 cm, vibrating in a direction normal to its faces with a frequency of 2700 KC, was determined at various temperatures. A second oscillating plate was used as a fixed frequency, while the heterodyne note was heard with a receiving set. This second plate was maintained at, or near, room temperature, and was reground to an appropriate frequency for each determination. The temperature coefficient of frequency was found to decrease linearly from 22.7 parts per million per degree at 65°C to 1.6 parts per million per degree at -189°C.Keywords
