Description

Bently Nevada 330101-00-16-10-02-05 Eddy Current Displacement Sensor Technical Profile

Core Product Introduction

The Bently Nevada 330101-00-16-10-02-05 is a high-precision 3300 XL 8 mm eddy current displacement sensor, a core component of Bently Nevada’s industry-standard machinery health monitoring ecosystem. Designed for non-contact, continuous measurement of shaft radial vibration, axial position, and dynamic displacement on critical rotating equipment, it delivers exceptional linearity and long-term stability even in harsh industrial environments. Natively interoperable with the Bently Nevada 3500 series machinery protection modules you previously researched, this sensor forms a fully API 670 compliant end-to-end monitoring solution for power generation, oil and gas, and petrochemical facilities, eliminating signal conversion risks and simplifying system integration.

Primary Technical Specifications

Recommended Peer Series Models

1. ‌Bently Nevada 330101-00-08-10-02-00‌: Standard 8 mm eddy current probe with 2 m integral cable, the most widely deployed general-purpose variant for standard machinery monitoring points.
2. ‌Bently Nevada 330101-00-12-10-02-05‌: 3 m integral cable variant, optimized for medium-sized turbine and compressor installations requiring moderate wiring length between probe and junction box.
3. ‌Bently Nevada 330101-00-30-10-02-00‌: Extended 7.6 m integral cable version, tailored for large steam turbine facilities with long wiring distances between measurement points and the central monitor rack.
4. ‌Bently Nevada 330104-00-05-10-02-00‌: 5 mm compact eddy current probe, designed for installation scenarios with extremely limited physical space that cannot accommodate the standard 8 mm probe footprint.

Professional Quality Control Test Standard Operating Procedure

1. ‌Pre-Power Visual Inspection‌: Verify no physical damage to the sensing tip, probe body, cable jacket, and connector pins; confirm no cuts, abrasions, or loose components along the entire cable length.
2. ‌Coil Impedance Validation Test‌: Measure the internal probe coil impedance with a precision LCR meter at 1 kHz, confirm the reading falls strictly within Bently Nevada’s factory-specified tolerance range.
3. ‌Full-Range Calibration Test‌: Mount the probe on a Bently Nevada TK-3 calibration kit, adjust the target gap from 0 mm to 2.0 mm in 0.25 mm increments, validate output voltage maintains 7.87 V/mm linearity within ±5% across the full measurement range.
4. ‌Temperature Cycling Screening Test‌: Place the probe in a temperature-controlled chamber, run 10 cycles of -35°C to +175°C with 1-hour dwell time at each extreme, confirm no sensitivity drift exceeds ±2% after test completion.
5. ‌Cable Mechanical Durability Test‌: Apply specified tensile load on the cable for 10 minutes, then perform 500 cycles of 90-degree bending test, confirm no open circuit or signal discontinuity occurs during and after the test.
6. ‌72-Hour Continuous Burn-In Test‌: Power the transducer under rated -24 V DC supply, operate it at the mid-point of the linear gap range for 72 consecutive hours, record all output logs, and only release units with zero fault records for shipment.

New Module Installation Guidelines

1. Confirm the target rotating machinery is in full locked-out/tagged-out shutdown status before installation, select a mounting position perpendicular to the clean, uncoated shaft surface to avoid measurement distortion.
2. Thread the probe into the pre-drilled mounting hole, adjust the initial mechanical gap to set the gap voltage to ‌-10 V DC ± 1 V‌ as specified in Bently Nevada’s official installation manual, then tighten the lock nut securely to fix the probe position.
3. Route the probe cable separately from high-voltage power cables, avoid sharp bends with radius less than 25 mm, connect all extension cable and preamplifier connectors tightly with proper locking mechanism.
4. Power on the Bently Nevada 3500 monitoring rack, verify the gap voltage reading on the 3500/42M or 3500/45 monitor is stable and within the normal working range, then perform a full gap calibration validation before putting the system into formal operation.

Application Scenarios and Core Features

This sensor is widely deployed on steam turbines, centrifugal compressors, gas turbines, large industrial pumps, and induced draft fans in power plants, refineries, and petrochemical facilities. Its core advantages include industry-proven long-term measurement stability, wide operating temperature adaptability, and native seamless compatibility with your existing Bently Nevada 3500 series machinery protection system. It can be directly paired with 330730 series extension cables and 3500 series monitoring modules to build a complete, API 670 certified machinery protection solution that meets strict industrial safety and reliability requirements.
