Parallel or Serial Resonance Frequency
I'm just writing some theory about QCM in my thesis. Now I wonder if the openQCM is actually driven at the parallel or at the serial resonance frequency.
Hi schurli111 ,
openQCM use a quartz driver (SN74LVC1GX04) that can nominally operate between few KHz up to 28 MHZ. With external component it is a true pierce scheme circuit that "link" to the parallel resonance of every quartz in the described frequency range.
