Detail Introduction

Components Used in Screw Fastener Sensors

The piezoelectric components is fastened to the metal rod with bolts, which enable the particle displacement or velocity of the mechanical vibration of the piezoelectric components to be amplified, and the ultrasonic energy is concentrated on the smaller area, that is, the ultrasonic concentrator. We can provide a variety of ring-shaped components with low resonant impedance, low dielectric loss, good thermal stability, and high power drive.
