ProductsCompany
PCB Piezotronics was founded in 1967 as a manufacturer of piezoelectric quartz sensors, accelerometers,and associated electronics for the measurement of dynamic pressure, force, and vibration.The unique expertise of the company was the incorporation of microelectronic signal conditioning circuitry within these sensors to make them easier to use and more environmentally compatible.
