📘 Product Profile: Bently Nevada 330100‑90‑02

🔧 Product Introduction

The 330100‑90‑02 is a proximitor / proximity transducer module (also called a signal conditioning module) designed to interface with eddy-current probes and extension cables in rotating machinery monitoring systems. It is part of the proximity sensing system family designed to provide stable, conditioned outputs from raw probe signals. The “90” in the model indicates a 9.0 meter (or equivalent) cable or assembly length implication, and the suffix “02” suggests a variant with certain approvals or connector options.

As a module, it is typically mounted close to the probe or in an instrument enclosure, conditioning the probe’s output into a linear and reliable signal that can be consumed by monitoring systems, protective relays, or data acquisition units. It is designed to operate within industrial environments, often subject to vibration, temperature extremes, humidity, and electrical noise.

This module is compatible with the standard proximity transducer ecosystem, and is suited for critical machinery health monitoring in power generation, oil & gas, petrochemical, and industrial plants.

Notes on Dimensions & Weight

• The module housing dimension estimate (100 × 55 × 65 mm) excludes protruding connectors or cable glands.

• The weight (~0.32 kg) is for the module alone; cable assemblies or external wiring add further mass.

• As with other proximitor modules, the mechanical design is compact to allow placement near the measurement zone.

🏭 Applications

The 330100‑90‑02 module is used wherever shaft displacement, vibration, or run-out monitoring is required in industrial rotating machinery. Key application areas include:

• Steam turbines, hydro turbines, and gas turbines

• Large compressors and pumps

• Generators and motor-driven rotating systems

• Refineries, petrochemical facilities, and chemical plants

• Power generation plants and auxiliary systems

• Critical rotating equipment in chemical, metallurgical, or mining industries

• Machinery protection, condition monitoring, predictive maintenance systems

• Environments subject to vibration, heat, humidity, or electrical interference

By conditioning the raw eddy-current probe output, the module ensures that downstream systems receive a clean, stable signal for instrumentation, alarming, or shutdown logic.

⭐ Product Advantages

• ✅ Long Reach Support: Designed to support 9.0 m installations without loss of signal quality.

• ✅ Stable Signal Conditioning: Maintains linearity, low drift, and low noise performance.

• ✅ Robust Build: Rugged housing to withstand industrial stress (vibration, moisture, heat).

• ✅ Approval Variants: The “02” variant likely includes compliance or enhanced connector options.

• ✅ Humidity Tolerance: With proper sealing, can operate in 100% relative humidity environments.

• ✅ Compact Form Factor: Size and weight allow placement close to measurement zones, minimizing signal path.
