PZTs can be found that will work perfectly well at liquid nitrogen temperatures. Indeed, I've personally used bimorph discs as sonar elements at 95K without a hitch and have dunked them in LN2 with no ill-effects. However the bonding method used to attach the...

I've been using cryogenic thermometers of one sort or another for 20 years and for the life of me cannot see how these three acronyms tell me anything specific about a device.

You may still, depending on payload, struggle to dissipate...
