Quartz-type gas pressure gauge

摘要

The present invention deals with a quartz-type gas pressure gauge which utilizes resonance of a quartz vibrator that changes depending upon the pressure, wherein the quartz vibrator is of the type of tuning fork obtained from a Z-plate of quartz crystal that is cut at an angle of greater than 1 DEG 50' with respect to the Y-axis, in order to prevent the occurrence of erroneous measurement that will be caused by the change of ambient temperature particularly in low pressure regions.
