Piezo Quartz exhibits the best long term stability of any piezoelectric sensing material. Quartz exhibits no pyro-electric output and has a small stable thermal coefficient. The low capacitance of quartz gives it a high voltage output (V=Q/C).
BonTek Optoelectronics has enormous experience in Crystal Quartz Ring fabrication. We make 10 thounds of quartz rings and LiNbO3 rings each year. They are mostly used as the key element in pressure or force sensors. We can customize the outter dia., inner dia., surface finish, and cut angle for you.
