Piezo Ceramic Microphones
- Ceramic vibration designs
- High vibration sensitivity
- High resistance to mechanical shock
The piezo ceramic microphone series is rugged, stable, and versatile. Design variables include standard, thin, or a one-half inch cylindrical shell with a cable assembly. Both communication and broadband frequency responses are available. The series features high vibration sensitivity and may be used as accelerometers.
