Quick Detail

Description

The 3300 NSv Proximity Probe is a high-precision eddy current displacement transducer engineered for advanced industrial automation and machinery monitoring. Designed for use in centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation spaces, the 3300 NSv probe delivers reliable radial vibration, axial position, and speed measurements. Its compact M8x1 threaded case and small probe tip made of chemically resistant Polyphenylene Sulfide (PPS) allow accurate measurements in restricted counter bore, sideview, or rearview environments. With a linear range of 1.5 mm (60 mils), recommended gap of 1.0 mm (40 mils), and an average scale factor of 7.87 V/mm (200 mV/mil), the 3300 NSv provides precise eddy current signals compatible with Bently Nevada 3300 XL and legacy 3300 RAM systems. The probe operates reliably across a wide temperature range of -52°C to +177°C (-62°F to +351°F) and features AISI 304 stainless steel housing for robust industrial performance. Gold-plated ClickLoc connectors and TipLoc molded probe tips ensure secure electrical connections, while the patented CableLoc design provides 220 N (50 lb) of cable pull strength. The probe supports field wiring from 0.2 to 1.5 mm² (16 to 24 AWG) and offers less than 2 mV output change per volt input variation, ensuring stable and consistent signal output in critical automation systems.

Applications

Radial Vibration Monitoring
The 3300 NSv probe enables precise radial vibration measurements on small shafts under 51 mm (2 in), allowing early detection of imbalance or misalignment in centrifugal compressors. Its 1.5 mm linear range ensures accurate tracking of high-frequency vibration up to 1 kHz.

Axial (Thrust) Position Measurement
Ideal for axial shaft position measurement in fluid-film bearing machines, the probe provides real-time data to prevent thrust bearing overload. The 0.5-meter cable and M8x1 threading allow installation in confined machinery spaces.

Tachometer and Zero-Speed Detection
The probe accurately captures shaft speed and zero-speed events in refrigeration compressors, with 4–20 mA DC-compatible output and high input voltage stability (<2 mV change per V input).

Phase Reference (Keyphasor Signals)
Used in rotating machinery diagnostics, the 3300 NSv supports Keyphasor phase reference signals for synchronous vibration analysis and predictive maintenance programs.

Retrofit and Upgrade of Legacy Systems
The probe is compatible with existing 3300 RAM and 3000/7000-series transducer systems, allowing seamless upgrades while maintaining existing extension cables and monitoring setups, reducing downtime and installation costs.

Specifications

Competitive Advantage

Compact Design for Tight Spaces
The 3300 NSv probe’s small M8x1 case and 0 mm unthreaded length allow installation in restricted counter bore and sideview applications, outperforming standard 3300 XL probes in confined environments.

Enhanced Chemical Resistance
With PPS probe tip material and stainless steel housing, the probe withstands aggressive process environments, supporting operations in compressors handling reactive or high-temperature gases.

Superior Connector Reliability
Gold-plated ClickLoc connectors and the CableLoc design ensure a secure electrical connection with 220 N pull strength, minimizing signal loss in critical automation systems.

High Accuracy and Stability
With a linear range of 1.5 mm and output variation below 2 mV per volt input, the probe delivers precise displacement measurements, exceeding the linear range of older 3000-series 190 probes.

Interchangeability with Legacy Systems
Compatible with 3300 RAM and 3000/7000-series systems, the 3300 NSv allows upgrades without replacing monitoring infrastructure, facilitating cost-effective modernization of existing machinery.
