The Bently Nevada 330980 Proximity Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DIN-rail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting "footprint" with older Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates. The 3300 XL NSV (narrow side view) Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL NSV Proximitor Sensor's improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity.
The three parts of the system must have consistent electrical lengths. The electrical length of the Proximitor probe plus the electrical length of the extension cable must equal the electrical length of the Proximitor.
Features

- Highly immune to radio frequency interference
The Bently Nevada 330980 is a high-performance proximity sensor in the 3300 XL NSV series, designed to meet the demanding requirements of industrial machinery monitoring246.
- Compact and Versatile: The 330980 features a compact design, allowing for installation in high-density DIN-rail setups or traditional panel mount configurations124. It shares the same 4-hole mounting "footprint" as older proximitor sensor designs, providing convenience for replacement and upgrade12.
- Electrical Isolation: The mounting base of the sensor offers electrical isolation, eliminating the need for a separate isolator plate and simplifying the installation process12.
- High Immunity to Interference: This sensor is highly immune to radio frequency interference (RFI) and electromagnetic interference (EMI)124. It can be installed in fiberglass housings without being affected by nearby radio frequency signals, and its improved RFI/EMI immunity meets European CE mark approvals without requiring special shielded conduit or metallic housings24.
- Accurate Measurement: Based on eddy current sensing technology, the 330980 provides precise measurements of displacement, position, and vibration4. It has an operating voltage range of 18 VDC to 30 VDC and a standard current output of 4 – 20 mA, which is suitable for various industrial applications4.
- Wide Frequency Response: With a high-frequency response range, it is capable of monitoring vibrations and analyzing machine health effectively4.
- Wide Temperature Range: The sensor can operate stably within the temperature range of -40 °C to +85 °C (-40 °F to +185 °F), demonstrating excellent adaptability to different working environments4.
The 330980 is widely used in a variety of industrial fields6. It is mainly used in fluid-filmed bearing machines, such as centrifugal air compressors, refrigeration compressors, and process gas compressors6. Its applications include radial vibration and position measurement, axial (thrust) position measurement, tachometer and zero speed measurement, and phase reference (keyphasor) signal detection6. Especially in scenarios where there are small shafts or reduced side views, or when standard transducer systems are restricted by installation space, the 330980 shows its unique advantages6.
In conclusion, the Bently Nevada 330980 proximity sensor, with its advanced features, high reliability, and wide range of applications, plays a crucial role in ensuring the safe and efficient operation of industrial machinery, making it an ideal choice for machinery protection and predictive maintenance systems
