Quick Detail

Description

The 330980-70-05 3300 XL NSv Proximitor Sensor is designed for demanding industrial automation and rotating machinery monitoring applications where space constraints, small shaft dimensions, and side-view limitations restrict the use of standard proximity transducer systems. As part of the Bently Nevada 3300 XL NSv family, the 330980-70-05 sensor offers precise radial vibration, axial position, and tachometer/phase reference measurements on fluid-film bearing machines, compressors, and small turbo machinery. The system supports a linear measurement range of 1.5 mm (60 mils) with an output scale factor of 7.87 V/mm (200 mV/mil), enabling accurate tracking of shaft dynamics. Constructed with A380 aluminum housing and compatible with 3300 NSv probes and extension cables, the Proximitor Sensor features panel mounting, 7.0 m total system length, and multiple global approvals for industrial use. With an operating temperature range of -52°C to +100°C, supply sensitivity below 2 mV per volt change, and 100% condensing humidity tolerance when connectors are protected, the 330980-70-05 sensor maintains signal stability and data reliability in harsh control environments. Mechanical robustness is further enhanced by ClickLoc-style connectors, secure wiring compatibility from 16–24 AWG, and industry-recognized durability for process compression, machine diagnostics, and automated condition monitoring applications.

Applications

Radial Vibration Monitoring on Small Shafts
Used on compressor and turbine shafts under 51 mm diameter, leveraging a 1.5 mm linear range and 7.87 V/mm sensitivity for real-time vibration diagnostics in predictive maintenance platforms.

Axial (Thrust) Position Tracking
Applied to thrust position measurements on fluid-film bearing machines; the 200 mV/mil scale factor supports precise axial signal feedback into machine protection systems and shutdown logic.

Tachometer and Keyphasor Reference Inputs
Provides phase and speed measurement signals for synchronous calculations and balancing; stable output resistance of 50 Ω ensures reliable timing reference for high-speed rotors.

Refrigeration and Gas Compressor Control
Operates in refrigeration and process gas compressors where clearance constraints restrict sensor access; the panel-mount configuration supports compact control cabinets in OEM skid packages.

Machine Health Monitoring in High Humidity Plants
100% condensing humidity tolerance enables deployment in indoor industrial environments, such as petrochemical or LNG facilities, where moisture and temperature fluctuations impact electronic sensors.

Specifications

Competitive Advantage

Superior Small-Target Performance
Designed for shafts below 51 mm and flat targets below 15 mm; optimized NSv geometry enhances measurement integrity where conventional 5 mm and 8 mm probes lose accuracy.

Extended Environmental Endurance
Operates from -52°C to +100°C and stores up to +105°C, outperforming typical condition monitoring sensors limited to ~85°C, ensuring wider deployment in compressor housings and insulated cabinets.

High Measurement Sensitivity and Linearity
Provides 7.87 V/mm (200 mV/mil) scale factor with 1.5 mm linear range, yielding more detailed displacement resolution than legacy 3000-series 190 transducers with shorter usable range.

Compatibility and Upgrade Flexibility
Electrical/mechanical compatibility with 3300 RAM probe systems reduces retrofit costs; allows reuse of existing probes/cables for upgrades, improving OEM and maintenance economics.

Enhanced Connector Reliability and Sealing
ClickLoc connectors and CableLoc design provide up to 220 N pull strength and minimize signal degradation under high vibration; connector protectors reduce liquid ingress risk in condensing plants.
