Bently nevada 9200-01-02-02-00 speed sensor
The 9200-01-02-02-00 is a two-wire brake ring speed sensor from the Bently Nevada 9200 series. Its core function is to measure the absolute vibration (relative to free space) of bearing housings, machine casings, or structures, and output a voltage signal proportional to the vibration velocity. It is suitable for continuous monitoring and portable diagnostics and is widely used in the condition monitoring and fault early warning of rotating machinery in industries such as power, petrochemical, and metallurgy to ensure stable equipment operation.

Core Functions
Absolute Vibration Measurement: Directly measures the absolute vibration velocity of bearing housings, casings, or structures, reflecting the overall vibration state of the equipment. Unlike relative vibration measurement, it is more suitable for non-shaft vibration monitoring.
Passive Signal Output: Two-wire design eliminates the need for external power supply, simplifying wiring and adapting to portable measuring instruments for convenient on-site inspection and fault diagnosis.
Impact Interference Resistance: Moving-coil technology reduces sensitivity to impact or pulse excitation, resulting in more stable measurements suitable for long-term monitoring under complex operating conditions.
Wide Frequency Response: Covers the frequency range of common rotating machinery faults (such as imbalance, misalignment, looseness, etc.), meeting API 670 and other standard requirements.
System Compatibility: Can be used with 9513 speed-displacement converters, 3500/20 monitoring modules, 2300 series monitors, etc., to achieve data acquisition, alarm, and protection.
Applications and Typical Scenarios
Power Industry: Vibration monitoring of bearing housings in auxiliary equipment such as steam turbine generators, water turbines, feedwater pumps, and fans in thermal power plants/hydropower stations, providing early warning of bearing wear, rotor imbalance, and other faults. Petrochemical Industry: Vibration monitoring of compressor, pump, and centrifuge casings, suitable for continuous production scenarios, reducing unplanned downtime.
Metallurgy and Manufacturing: Condition monitoring of rotating machinery such as rolling mills, coal mills, and motors, enabling periodic inspections and fault location with portable instruments.
Predictive Maintenance: Long-term monitoring of vibration trends, combined with data analysis to identify early faults, optimize maintenance plans, and reduce maintenance costs.
Portable Diagnostic Applications: Compatible with portable devices such as vibration analyzers for equipment commissioning, fault diagnosis, and periodic testing, improving operational efficiency.
