Vidim da je čika HP odavno skontao ovu metodu merenja temperature preko kristala i frekvencije, skontali su da menjanjem ugla pod kojim se reže kristal da se utiče na temperaturni koeficijent, tako postoje "LC cut" (LC rez, Linear Coeficient) kristali koji imaju linearnu zavistnost promenu fekvencije naspram temperature u relativno širokom opsegu temperatura, na primer tako postižu merenja temperature u opsegu -50*C do +250*C sa neverovatnom tačnošću 0.0001*C
