fr, Zm, Kp => Radial mode by impedance analyzer.
Cs => LCR meter at 1KHz 1Vrms
Applications: Bolt-clamped ultrasonic transducer, Ultrasonic Sensor, Vibration Sensor, Pressure, sensor, Vibration generation, Biodiesel mixing transducer, Piezo expansion sensor, compression sensor, Piezo Welding, Tonpilz and others.
Notes: Keff = ≥35%. Keff is calculated by the formula, ((fa2-fr2)/fa2), and fa is the anti-resonant frequency of the hoop mode.
