Overview：
Bently Nevada 330500-00-04 Velomitor Piezo-velocity Sensor
Bently Nevada 330500-00-CN Velomitor is a piezoelectric velocity sensor used to directly measure the absolute vibration (relative to free space) of machine bearing housings, casings, or structures. The sensor integrates a piezoelectric acceleration sensing element with built-in signal conditioning and integration circuitry within a single housing, providing a voltage output proportional to vibration velocity without the need for an external integrator.

Fuction&Features:
- Direct velocity output:The 330500-00 features built-in circuitry that directly integrates the piezoelectric acceleration signal, providing an analog voltage output proportional to vibration velocity (mm/s, in/s). This output corresponds to the physical quantity most consistent with ISO vibration evaluation standards.
- Solid-state design:The 330500-00 contains no moving coils or magnets, fundamentally avoiding performance degradation or failure caused by mechanical wear, aging, or impact that commonly affect traditional moving-coil velocity sensors.
- Omnidirectional mounting:The 330500-00 is not affected by gravity orientation and can be installed vertically, horizontally, or at any angle.
