Quick Detail

Description

The 330704-000-060-90-02-CN is a specialized high-performance transducer within the 3300 XL 11 mm Proximity Probes series, specifically engineered by Bently Nevada for heavy-duty industrial machinery monitoring. This model is distinguished by its extended 600 mm overall case length and a 0 mm unthreaded configuration, making it an ideal solution for deep-well installations where the probe must reach through thick machine casings to monitor shaft behavior. As a primary component of the 3300 XL 11 mm Proximity Probes system, the 330704-000-060-90-02-CN utilizes advanced eddy current technology to provide non-contacting, high-precision displacement and vibration data.

A significant advantage of the 3300 XL 11 mm Proximity Probes is the expanded 4.0 mm (160 mils) linear range, which is double that of standard 8 mm probes. This makes the 330704-000-060-90-02-CN particularly effective for monitoring large-scale rotating assets like steam turbines and generators where greater shaft movement or thermal expansion is expected. The probe features the patented TipLoc molding process, ensuring a permanent bond between the probe tip and body, and the CableLoc retention system, which provides a robust 330 N (75 lb) pull strength to prevent cable detachment in high-stress environments.

Applications

The 330704-000-060-90-02-CN is primarily applied in large-scale rotating machinery for axial (thrust) position monitoring. Its 4.0 mm extended linear range is essential for detecting the axial float of massive shafts in steam and gas turbines. Given its 600 mm extra-long case length, this probe can be installed through complex outer housings to reach the thrust collar, providing critical data to prevent rotor-to-stator contact during thermal transients or load changes.

This probe is frequently used for measuring rotor eccentricity and radial vibration in low-speed and high-load industrial machines. In hydro-turbines and large pumps, the 330704-000-060-90-02-CN captures subtle shaft movements that indicate unbalance or bearing wear. The 9.0-meter total length allows the cable to be routed directly from deep within the machine to external junction boxes, simplifying the wiring architecture for continuous condition monitoring systems.

The 330704-000-060-90-02-CN serves as a reliable Keyphasor reference and speed sensing tool for machines with significant surface irregularities or large gaps. Its robust construction allows it to operate in extreme temperatures from -42°C to +157°C. The integrated connector protector and Miniature coaxial ClickLoc connector ensure that even in environments with high humidity or oil mist, the signal remains stable for phase analysis and overspeed protection functions in petrochemical refineries and power plants.

Specifications

Competitive Advantage

Extended 4.0 mm Linear Range for Large Shafts: Unlike standard 8 mm probes, the 330704-000-060-90-02-CN offers a much wider linear measurement range of 4.0 mm (160 mils). This provides a significantly larger "safety window" for monitoring machines with high vibration levels or significant thermal growth, reducing the frequency of probe re-gapping and preventing signal saturation during peak operational loads.

Ultra-Long 600 mm Case Design: The specialized 600 mm overall case length is a major competitive advantage for the 3300 XL 11 mm Proximity Probes. This configuration eliminates the need for complex mounting brackets or extension sleeves when monitoring shafts located deep within double-walled machine casings, ensuring a more rigid and accurate installation that is less susceptible to parasitic vibrations.

Superior Signal Integrity and Stability: With a supply sensitivity of less than 2 mV per volt change and a precise 50 Ω output resistance, the 330704-000-060-90-02-CN delivers exceptionally stable data. The low extension cable capacitance (65.2 pF/m) ensures that high-frequency vibration signals are transmitted accurately over the 9.0-meter cable without attenuation, providing more reliable fault diagnostics than lower-tier proximity sensors.

Patented Ruggedized Construction: The combination of TipLoc and CableLoc technologies ensures that the probe tip and cable can withstand the physical rigors of industrial installation. With a 330 N pull strength and a high-grade PPS tip material, this probe offers a service life that often exceeds that of the machinery it monitors, even when exposed to harsh lubricating oils and moisture.
