BENTLY NEVADA 330500-03-00 Velomitor Piezo-velocity Sensor

Description

The BENTLY NEVADA 330500-03-00 Velomitor Piezo-velocity Sensor is a piezoelectric-based velocity sensor designed for industrial vibration monitoring. It utilizes piezoelectric crystal technology with an integrated circuit embedded in an accelerometer, which converts vibration acceleration signals into velocity output. A key feature is its solid-state design with no moving parts, eliminating mechanical wear and degradation for long-term reliable operation. This sensor supports flexible installation, including vertical, horizontal, or any angle mounting, with no special calibration required, simplifying deployment in diverse setups. Its core technical specifications include a frequency range of 4.5Hz to 5kHz (±3dB) and a sensitivity of 3.94mV/mm/s (100mV/in/s) ±5%. Primarily used to measure absolute vibration (relative to free space) of bearing housings, machine enclosures, or structural components, it is ideal for condition monitoring of rolling bearing equipment such as pumps and fans. It can also support gear mesh frequency monitoring when paired with an accelerometer. Note that rotor imbalance or misalignment faults may not be fully reflected by housing vibration, so measurement validity should be evaluated for such applications.
