Note on Piezoelectricity: Piezoceramic materials may lose piezoelectric properties due to depolarization when exposed to high temperature or high voltage.
Note on Soldering: Transducer is not designed for reflow soldering. Do not use reflow ovens.
Note on Electric Connection: Do not connect transducer to DC voltage.
Note on Installation: Protect transducer with buffer material at installation to prevent noise induction from vibration.
Note on Water-proof: Not a water-proof device. Avoid exposure to water, organic solvents, and corrosive gases. Keep surface clean; do not touch with skin or clean with organic solvents.
