A somewhat related question. Can a quartz crystal be used as a pressure (actually
medium to high vacuum) sensor? Specifically, over the range of perhaps 1 Torr to
1e-6 Torr. IOW, over about the same range as a thermocouple gauge.
At first blush it would seem a natural application. Not knowing what the second
blush is.... :-)
