Piezoelectric Disc Of Diameter 27.4 mm For Fishing Finder
Transducer
1. Product description
Piezoelectricity is a type of electricity that occurs when
materials possessing piezoelectric properties are exposed to
pressure or stress. Examples of these materials are ceramics, also
called piezoceramics , and crystals.
Piezoelectric Ceramics (piezoceramics), such as Piezoelectric
Ceramic Ring, Piezoelectric Ceramic Disc, Piezoelectric Ceramic
Tube, Piezoelectric Ceramic Ball/Hemisphere, Piezoelectric Ceramic
Cylinder and Piezoelectric Ceramic Square/Rectangular.
