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

Description

The BENTLY NEVADA 330500-00-00 Velomitor Piezo-velocity Sensor is a general-purpose vibration measurement device that uses piezoelectric crystal technology with an integrated integral circuit to convert vibration acceleration into a velocity signal output. Key features include a non-moving component design, which eliminates mechanical wear and degradation for long-term reliability. It supports flexible installation in vertical, horizontal, or any angular orientation without requiring special calibration. Technical specifications cover a frequency range of 4.5Hz to 5kHz (±3dB) and a sensitivity of 3.94mV/mm/s (100mV/in/s) ±5%. This sensor is engineered to measure absolute vibration (relative to free space) of bearing housings, machine enclosures, or structural components. Typical application scenarios include condition monitoring of rolling bearing equipment such as pumps and fans, as well as gear mesh frequency monitoring when paired with an acceleration sensor. Note that rotor imbalance or misalignment faults may not be fully reflected by housing vibration, so measurement effectiveness should be evaluated for such use cases.
