Product introduction

The Bently Nevada 330851-02-000-060-10-00-00 is a complete proximity transducer system, designed to measure shaft displacement, position, and vibration in rotating machinery. This integrated solution includes a probe, extension cable, and driver, working together to provide precise, non-contact measurements critical for machinery protection and condition monitoring.

As a foundational sensing component, the 330851-02-000-060-10-00-00 converts mechanical motion into electrical signals, which are then processed by modules like the 3500/42M 140734-02 signal conditioner. Its 8 mm diameter probe offers a 6.0 mm linear measurement range, making it suitable for monitoring shafts in turbines, compressors, and motors across industries such as power generation and oil and gas.

Powered by reliable sources like the 3500/15 127610-01 redundant power supply, the 330851-02-000-060-10-00-00 delivers a 4-20 mA output signal that integrates seamlessly with the 3500/33-01-00 vibration monitoring module. This integration ensures that critical parameters—such as shaft position in a turbine—are continuously monitored, enabling early detection of issues like misalignment or bearing wear.

Core advantages and technical highlights

Non-contact precision measurement: The 330851-02-000-060-10-00-00 uses eddy current technology to measure shaft movement without physical contact, eliminating wear and tear on both the probe and machinery. This non-intrusive design ensures accurate readings even in high-speed applications (up to 20,000 RPM), where contact-based sensors would fail. Its 0.1% linearity within the 6.0 mm range ensures reliable data for critical diagnostics.

Integrated system design: Unlike separate components, the 330851-02-000-060-10-00-00 comes pre-calibrated as a complete system (probe, cable, driver), reducing installation errors and ensuring optimal performance. The 5 m shielded cable minimizes electromagnetic interference, while the driver’s temperature-compensated circuitry maintains accuracy across operating extremes—critical for applications like steam turbine monitoring, where temperatures vary widely.

Wide environmental tolerance: The probe withstands temperatures up to 120°C (248°F), making it suitable for high-heat environments such as gas turbine casings. The driver operates in 0°C to 60°C (32°F to 140°F) ranges, with both components resisting humidity and chemical exposure. This ruggedness ensures the 330851-02-000-060-10-00-00 performs reliably in offshore platforms, chemical plants, and other harsh industrial settings.

Seamless 3500 series integration: The system’s 4-20 mA output is optimized for the 3500/42M 140734-02 signal conditioner, which processes the signal for analysis by the 3500/33-01-00 module. When paired with the 3500/15 127610-01 power supply, it ensures uninterrupted operation in redundant systems, making it ideal for safety-critical applications where measurement gaps could lead to catastrophic failures.

Typical application scenarios

In a coal-fired power plant, the 330851-02-000-060-10-00-00 is installed on the main steam turbine to monitor shaft displacement. Mounted near the turbine’s thrust bearing, the probe measures axial movement, while the driver converts this to a 4-20 mA signal. This data is processed by the 3500/42M 140734-02 and analyzed by the 3500/33-01-00, which triggers an alarm if displacement exceeds 4.5 mm—indicating potential thrust bearing failure. Powered by the 3500/15 127610-01, the system ensures continuous monitoring during turbine operation.

At an offshore oil platform, the 330851-02-000-060-10-00-00 monitors radial vibration on a centrifugal compressor shaft. The probe, mounted in the compressor’s bearing housing, detects shaft movement caused by imbalance or misalignment. Its 5 m cable routes through the platform’s harsh environment to a driver in a control cabinet, where the signal is sent to the 3500/33-01-00. When vibration exceeds 3.0 mm peak-to-peak, the 3500/62 module activates a shutdown, preventing compressor damage during storm conditions.

In a chemical plant’s mixer motor, the 330851-02-000-060-10-00-00 measures shaft position to detect bearing wear. Over time, data from the system—processed by 170180-01-00 software—reveals a gradual increase in radial movement, indicating bearing degradation. Maintenance teams use this trend data to replace the bearing during a scheduled shutdown, avoiding unplanned downtime and preventing contamination of the chemical process.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 330851-02-000-060-10-00-00, ensure the machinery is shutdown and locked out. Mount the probe using the M10 x 1.0 thread, positioning it 1.5 mm from the shaft surface (use a 330180-90-05 tool for gap setting). Route the 5 m cable away from high-voltage lines to avoid interference, securing it with non-metallic clips. Mount the driver on a DIN rail or panel in a clean, dry enclosure, and connect it to the 3500/15 127610-01 power supply (24V DC).

Maintenance suggestions: Inspect the 330851-02-000-060-10-00-00 quarterly for probe damage, cable wear, or loose connections. Clean the probe tip with a soft cloth to remove oil or debris, which can affect measurements. Verify the gap voltage (typically 8V DC) annually using a multimeter; adjust if drift exceeds ±0.5V. Calibrate the system every 2 years with a 330101-05-00 calibration kit to ensure linearity. Replace the cable if insulation damage is found, as moisture ingress can corrupt signals.
