330752-25-CN is a Bently Nevada high temperature Velomitor vibration system designed for direct vibration velocity measurement in harsh industrial machinery environments. The system supports continuous monitoring of casing vibration on turbines, compressors, pumps, and heavy rotating equipment operating under elevated thermal stress. It maintains stable signal output where conventional accelerometer systems lose accuracy due to temperature drift.
This model is widely deployed in power generation, petrochemical refining, and steel production lines where equipment operates in sustained high temperature zones. The CN suffix indicates China-specific hazardous area approval coverage, supporting compliance for explosion risk environments. The system improves early fault detection and reduces unplanned downtime by providing reliable velocity-based vibration data under thermal and mechanical stress conditions.
330752 = High Temperature Velomitor System platform
25 = 2.5 metre system length
CN = China country-specific hazardous area approvals (NEPSI related certification support)
The system is designed for direct integration with Bently Nevada monitoring platforms and supports consistent velocity signal transmission under long cable routing conditions. It maintains signal integrity in electrically noisy industrial environments when properly grounded and shielded.

Can the 330752 system operate in turbine casing high temperature zones?
Yes. It is designed for elevated temperature environments commonly found in gas turbines and steam turbines.
What does CN approval mean for this model?
CN indicates China-specific hazardous area certification support, including NEPSI-related compliance for explosive environments.
Is this system compatible with standard Bently Nevada monitoring racks?
Yes. It integrates with compatible Bently Nevada vibration monitoring systems designed for Velomitor inputs.
What is the main advantage over accelerometer-based systems?
Velocity-based measurement provides more stable readings for low-frequency casing vibration in heavy rotating machinery.
Install the sensor on a rigid, clean mounting surface to ensure accurate vibration transmission. Loose mounting reduces signal fidelity and increases measurement noise.
Use high-temperature rated cable routing paths and avoid direct contact with hot piping surfaces above design limits. Thermal insulation improves long-term cable reliability.
Ensure proper grounding at a single point to prevent ground loop noise, especially in turbine control rooms with high electromagnetic interference levels.
