A one-package solution for the PLL control function necessary for resonance point tracking.
The Piezo Resonance Point Tracking Module PD-660-S1 is a control module specialized for tracking the resonance points of piezoelectric elements, making it suitable for integration into various ultrasonic application devices. By connecting it to a piezoelectric drive amplifier, it can automatically track the resonance points of devices such as BLTs (Langevin transducers) while enabling optimal drive. Adjusting various parameters is also easy, which can lead to reduced development time and cost savings.
