1. Product Overview — Bently Nevada 330850‑51‑CN

Introduction

The Bently Nevada 330850‑51‑CN is a non‑contact proximity sensor / “Proximitor” module in the 3300 XL 25 mm sensor family. It is intended to measure shaft displacement, radial vibration, or position in rotating machinery via a probe + extension cable + proximitor chain.

The suffix “‑CN” typically indicates a China / Chinese market compliance / configuration or localized variant (for example tailored approvals or packaging). It shares core performance with other 330850 series models but may incorporate regional certification or labeling.

This model is suited for monitoring turbines, compressors, pumps, fans, motors in settings requiring continuous online monitoring and fault detection.

2. Technical Specifications — 330850‑51‑CN

Below is a table of expected / representative specifications for the 330850‑51‑CN variant:

Note: The dimensions and weights above are inferred from similar 330850‑51 series models; “CN” variant differences are minor (labeling, approval, internal layout) and do not materially alter physical size or mass.

3. Applications

The 330850‑51‑CN finds use in numerous industrial applications where monitoring of rotating machinery is essential. Typical application domains include:

• Steam and gas turbines (shaft radial displacement / vibration monitoring)

• Large electrical generators in power plants

• Centrifugal and reciprocating compressors

• Pumps and motors in process plants (chemical, petroleum, petrochemical)

• Fans, blowers, and ventilation systems subject to variable load

• Rotating equipment in mineral processing / mining

• Condition-based monitoring (CBM) and predictive maintenance systems

In all these cases, the 330850‑51‑CN is used to track small movements of the rotor relative to its stationary parts, detect imbalance, misalignment, bearing wear, and provide signals to protective systems or condition monitoring platforms.

4. Advantages & Key Features

Below are the main advantages and features of the 330850‑51‑CN model:

1. Non-contact Sensing
   The sensor does not physically touch the rotating shaft, eliminating wear, friction, and maintenance issues associated with contact sensors.

2. High Accuracy & Linearity
   Delivers stable, linear outputs over the measurement range. Drift is minimized, enabling precise trending and fault diagnosis.

3. Robust EMI / RFI Immunity
   Designed for heavy industrial electromagnetic environments, reducing susceptibility to noise and interference.

4. Regional Compliance (“CN” variant)
   Provides localized labeling, regulatory compliance, and perhaps packaging suited for the China region, facilitating approvals and deployment.

5. DIN Rail Mounting / Compact Form
   The “51” style supports DIN rail installation, making integration into control panels and relay racks simpler and space-efficient.

6. Interchangeability & Compatibility
   Compatible with probes, extension cables, and monitoring hardware in the 3300 / 3300 XL family, simplifying upgrades or replacements.

7. Wide Operating Temperature & Harsh Environment Capability
   Compatible with extremes of temperature, vibration, humidity, and electrical stress typical in industrial settings.

8. Long-term Reliability
   Designed for extended duty, reducing downtime and maintenance overhead in mission-critical systems.
