Piezoelectric Vibration Velocity Sensors（ DC Supply Mode）
TL series Piezoelectric Vibration Velocity Sensors are solid-state piezoelectric velocity measurement devices. Many vibration analysts prefer to examine vibration signals in terms of velocity (mm per second) to amplify the signal of interest. Piezoelectric Velocity Sensors inherently decrease high-frequency signals allowing better measurement of low-frequency vibration. They are essentially accelerometers with an internal integration circuit which will produce an output relative to velocity.
