Bently nevada 330980-50-00 Eddy current preamplifier
The 330980-50-00 is a Bently Nevada 3300 XL NSv series eddy current preamplifier. Its core function is to provide high-frequency excitation for the 3300 XL NSv eddy current probe and convert the change in the probe-shaft clearance into a standard linear voltage signal. It is compatible with the 3300 XL NSv 8mm sensor system and is designed for use in confined installation spaces. It can be used for radial/axial displacement, vibration, key phase, and speed measurement of rotating machinery. It is widely used in the condition monitoring and fault early warning of key equipment in industries such as power, petrochemical, and metallurgy to ensure the safe and efficient operation of equipment.

Core Functions
High-Frequency Excitation and Signal Conversion: Provides high-frequency AC excitation for the NSv probe coil, converting impedance changes caused by gap variations into a standard linear voltage signal, enabling precise non-contact measurement.
Signal Conditioning and Amplification: Conditions and amplifies the probe signal, improving the signal-to-noise ratio, ensuring signal integrity, and meeting the data acquisition accuracy requirements of the monitoring system.
Small Space Adaptability: Compact design adapts to confined installation spaces, such as high-density DIN rails or traditional panel mounting scenarios, expanding application range.
System Compatibility and Integration: Matches the 3300 XL NSv sensor system, supports 3300/3500 monitoring frames, simplifies data acquisition and analysis processes, and facilitates integration with host computer systems.
Multiple Safety Protections: Features reverse power connection protection and output short-circuit protection; wiring errors will not damage the preamplifier, improving equipment reliability.
Wide Temperature Stable Operation: Adapts to a wide temperature range of -51~121℃, meeting the long-term online monitoring needs of complex industrial environments.
Applications and Typical Scenarios
Power Energy: Monitoring shaft vibration and axial displacement in equipment such as steam turbines, generators, and pumps. Works in conjunction with the 3500 system for fault diagnosis and safety interlocking, conforming to API 670 standards.
Petrochemical Industry: Monitoring the shaft condition of compressors, fans, and gearboxes, acquiring key phase and speed signals to ensure long-term operation and prevent equipment failures.
Metallurgical Heavy Industry: Monitoring vibration and displacement in heavy-duty equipment such as rolling mills and coal mills, capturing shaft anomalies in real time to prevent downtime caused by bearing wear, rotor imbalance, etc.
Confined Space Applications: Suitable for equipment with limited installation space, such as small compressors and pump sets, replacing traditional 3300 RAM sensor systems to improve monitoring accuracy and stability.
System Upgrades and Retrofits: Replaces the 3300 RAM sensor system and the 3000/7000 series 190 sensor system, enabling upgrades and performance improvements for older equipment monitoring systems.
