Models covered
YMC Series Piezoelectric Vibration Velocity Sensors are solid-state piezoelectric velocity measurement devices. Many vibration analysts prefer to examine vibration in terms of velocity (mm/s) to amplify the signal of interest. Piezoelectric velocity sensors inherently attenuate high-frequency signals, allowing better measurement of low-frequency vibration. They are essentially accelerometers with an internal integration circuit producing an output proportional to velocity.
Features
- Output proportional to vibration in velocity
- Mount at any angle
- Transmit signals over long distance without signal loss (4-20 mA)
- Output to PLC, DCS, SCADA
Typical applications
- Permanent machine protection and monitoring
- PLC / DCS / SCADA integration
- Low-frequency vibration measurement
