Vibration Velocity Sensors

                                        YMC 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.

                                        Features:

                                        • deal for monitoring low-to-intermediate frequency applications

                                        • Generates an output proportional to velocity

                                        • Velocity measurements serve as a reliable guide for monitoring the severity of faults in slow-rotating equipment

                                        • Corrosion resistant and hermetically sealed

                                        • ESD and miswiring protection
