Quick Detail

Description

The 330104-05-18-50-02-05 3300 XL 8 mm Proximity Probes represent a specialized, long-reach variant of the renowned Bently Nevada eddy-current displacement transducer family. Engineered for demanding industrial applications, this particular probe configuration is defined by its extended overall case length of 180 mm and a substantial total cable length of 5.0 meters, offering unparalleled installation flexibility where sensor mounting points are distant from junction boxes or monitoring systems. As a precision component within the 3300 XL 8 mm Proximity Probes ecosystem, its core function is to provide non-contact, real-time measurement of dynamic mechanical motion, converting the minute gap between its probe tip and a conductive target into a highly stable, linear voltage signal. This output is fundamental for accurate analysis of radial vibration, axial position, and rotational speed in critical rotating machinery.

This model is built to endure the harshest operational environments, boasting an impressive operating temperature range from -55°C to +115°C. This thermal resilience ensures reliable performance in applications ranging from frigid outdoor installations to high-heat zones near turbines and compressors. The probe's mechanical integrity is ensured by its premium material construction: the sensing tip is made from high-performance Polyphenylene Sulfide (PPS), offering exceptional resistance to chemicals and thermal degradation, while the robust housing is fabricated from AISI 303 or 304 stainless steel (SST) for superior corrosion resistance and structural durability. A key feature of this specific variant is its 50 mm unthreaded length option, which provides significant flexibility for installations requiring precise axial positioning within threaded mounting holes.

Applications

This long-cable 3300 XL 8 mm Proximity Probe is ideally deployed in large-scale rotating equipment where monitoring points are located far from control cabinets, such as in expansive turbine halls, large compressor trains, or on offshore platforms. Its 5.0-meter cable length eliminates the need for intermediate junction boxes in many scenarios, simplifying installation and reducing potential failure points. The probe's extended 180 mm case length and 50 mm unthreaded section allow for secure mounting through thick machine casings or insulation, while its wide operating temperature range (-55°C to +115°C) ensures reliable performance for radial vibration monitoring of critical shafts, even in environments with extreme thermal gradients.

The probe is essential for axial thrust position monitoring in large turbines, pumps, and gearboxes where long cable runs are mandatory. The combination of its 2 mm linear range and stable electrical output (50 Ω resistance, <2 mV/V sensitivity) provides a precise and noise-resistant signal over the extended 5-meter cable, ensuring accurate measurement of shaft float to protect thrust bearings from damage. Its CSA, ATEX, and IECEx certifications make it particularly suitable for performing this safety-critical function in classified hazardous areas within refineries, gas processing plants, and petrochemical facilities, meeting stringent safety standards without requiring external protective conduits.

Specifications

Competitive Advantage

1. Extended Reach and Installation Versatility for Complex Layouts

This probe variant offers a significant total cable length of 5.0 meters as a standard, integrated feature. This eliminates the need for field splicing or additional extension cables in most applications, reducing installation time, potential signal integrity issues, and material costs. Combined with its 180 mm overall case length and 50 mm unthreaded length, it provides exceptional flexibility for mounting in deep or confined spaces, making it uniquely suited for large machinery and complex industrial layouts where sensor placement options are limited.

2. Certified for Global Use in High-Risk Hazardous Environments

The probe is pre-certified with CSA, ATEX, and IECEx approvals, providing a fully compliant, plug-and-play solution for hazardous area installations worldwide. This certification package allows for direct use in Zone 1/2 areas with explosive atmospheres, which is a critical requirement in sectors like oil & gas and chemical processing. It absolves end-users from the burden and expense of obtaining site-specific certifications, accelerating project timelines and ensuring regulatory compliance from day one.

3. Ruggedized Design for Long-Term Reliability in Extreme Conditions

Engineered with premium materials—a stainless steel (SST) housing and a Polyphenylene Sulfide (PPS) tip—this probe is built to withstand extreme operational challenges. Its wide operating temperature range (-55°C to +115°C) ensures stable performance in both cryogenic and high-heat environments. This rugged construction, coupled with stable electrical performance (2 mm linear range, 50 Ω output, low supply sensitivity), guarantees high-fidelity signal output and an extended service life, significantly reducing the total cost of ownership by minimizing maintenance interventions and unplanned downtime.
