Zener diodes can also be used to clamp voltages down to safe. 01uF capacitor and the 33 K resistor needs to be connected to ground, which is mistakenly not indicated in the diagram. These sensors rely on a piezoelectric material — often a quartz crystal or polycrystalline ceramic material — to sense changes in force. Too great of pulse will fracture the crystal and it will be ruined. This requires an AC driving voltage applied vertically across the plate, which uses the electro-mechanical. The piezoelectric effect is nowadays used in many everyday products such as lighters, loudspeakers and signal transducers. A few people were asking about them, so I've put. I was thinking of building a similar project but with a standard Piezo Disk. See the DNA-AI-211 as an example of a four-channel ICP/IEPE interface. Hobby Circuit designed by David Johnson P. It is a white to off-white solid.
