Bently Nevada 125065-12 2-conductor 18 AWG shielded cable

Frequently asked questions
Q:What measurement technology does this sensor use?
A:It uses piezoelectric sensing technology with integrated solid-state electronics to produce a direct velocity output.

Q:Where should the 125065-12 be installed?
A:The sensor is typically mounted on bearing housings or machine casings where vibration is transmitted from the rotating machine.

Q:Does the sensor require a specific mounting orientation?
A:No. Its solid-state construction allows installation in various mounting orientations without the limitations of moving-coil velocity sensors.

Description

The Bently Nevada 125065-12 is supplied as part of the 330500 Velomitor Piezo-Velocity Sensor family for continuous vibration monitoring on rotating equipment. It uses piezoelectric sensing technology together with integrated electronics to generate a direct velocity signal. Since the design contains no moving coil, the sensor avoids mechanical wear and maintains consistent performance regardless of mounting direction. The sensor is installed on bearing housings or machine casings to monitor casing vibration. The measured velocity signal can be used to identify changes associated with imbalance, shaft misalignment, mechanical looseness, and other vibration-related conditions. It is suitable for machinery protection systems as well as condition monitoring applications where reliable vibration information is required.
