Product Description

Overview

The Bently Nevada 100A1000 is a precision eddy current proximity probe engineered for shaft vibration, axial position, and speed monitoring in turbines, compressors, and industrial pumps. Part of the 3300 XL series, this sensor provides reliable, non-contact measurement of shaft movement and forms a critical component of machinery protection systems.

Designed for industrial-grade performance, the 100A1000 delivers accurate signals even in harsh operating environments and integrates seamlessly with Bently Nevada proximitor sensors and extension cables to form a complete transducer system.

Key Features

• Non-contact eddy current measurement for vibration, axial position, and rotational speed

• High linearity and sensitivity across standard measurement ranges

• Rugged construction for long-term reliability in oil-filled or high-temperature environments

• Compatible with Bently Nevada 3300 XL series proximitor systems

Technical Specifications

Performance Characteristics

• Precision Measurement: Detects minute shaft displacements with high linearity, providing reliable DC (gap) and AC (vibration) signals.

• Interchangeable Components: Standardized design allows probe or proximitor replacement without recalibration.

• Environmental Stability: Hermetically sealed probe withstands oil immersion and maintains accuracy under temperature fluctuations.

• Versatility: Suitable for radial vibration, axial thrust, and keyphasor/tachometer applications.

Applications

• Radial vibration monitoring of rotating machinery

• Axial shaft position measurement for rotor protection

• Keyphasor or tachometer signal generation for phase and speed tracking

• Integration into machinery protection systems and legacy 3000 Series installations

FAQ

Q: Can the 100A1000 probe operate in high-temperature oil environments?
A: Yes, the probe is hermetically sealed and stable from -35°C to +120°C for continuous operation.

Q: Is the 100A1000 compatible with modern 3300 XL systems?
A: Yes, it integrates with 3300 XL proximitor sensors and standard extension cables.

Q: How do cable lengths affect measurement accuracy?
A: Using a cable that doesn’t match the proximitor tuning can cause errors. Always match the cable length to the proximitor specification.
