102046-50 is a Bently Nevada custom Proximitor sensor featuring an advanced eddy current measurement mechanism optimized for a 5.0-meter total system length. Fully compatible with 3300-series 8mm proximity probes, this unit works seamlessly with industrial machinery monitoring systems to deliver flexible configuration and stable shaft displacement or vibration telemetry.

Features and benefits

High-precision measurement – Provides accurate vibration and position sensing.

• Customizable design – Tailored to specific machinery requirements.

• Reliable performance – Ensures consistent operation in harsh industrial environments.

• Compact construction – Suitable for space-constrained installations.

• Easy integration – Works seamlessly with Bently Nevada monitoring systems.

• Enhanced machinery protection – Supports early detection of potential equipment issues.

Specific Application

• Non-contact radial vibration and axial position monitoring on high-speed industrial rotating machinery.
• Shaft displacement measurements inside gas or steam turbines, compressors, and fluid-film bearing housings.
• Custom retrofitting configurations where a 5.0-meter total electrical system length (probe plus extension cable) is strictly required.

System Compatibility and Alternative Models

System Compatibility: Fully compatible with Bently Nevada 3300 series 8mm proximity probes and 3300 series extension cables. It interfaces with standard machinery monitoring platforms like the Bently Nevada 3500 Machinery Protection System. Requires a standard -24 VDC power supply.

Alternative Models: 330100-90-00 (9.0-meter standard system length Proximitor) or 330180-50-00 (3300 XL series 5.0-meter Proximitor Sensor).

Key Differences:

• System Length: The 102046-50 is calibrated specifically for a 5.0-meter total system length, whereas the 330100-90-00 is calibrated for a 9.0-meter configuration.
• Series Technology: The 102046-50 uses the classic 3300 series technology platform, while the newer 330180-50-00 utilizes the enhanced 3300 XL Proximitor design with improved RF noise rejection and micro-connector options.
