The Bently Nevada 330102-00-12-10-02-05 is a high-reliability eddy current sensor designed for non-contacting vibration and displacement monitoring. As a metric-threaded variant of the 3300 XL 8 mm system, it provides a linear voltage output proportional to the distance between the probe tip and a rotating shaft. This model is specifically engineered for international machinery standards requiring M10 x 1 mounting, offering superior thermal stability and moisture resistance in demanding industrial environments.
Technical Specifications
The configuration of the 330102-00-12-10-02-05 is defined by its metric mechanical interface and comprehensive global hazardous area certifications.
Thread Profile:M10 x 1 metric thread, precision-machined for standardized industrial mounting.
Case Geometry: 120 mm (approx. 4.7 in) overall case length with a 0.0 mm unthreaded portion, allowing for full-depth threading and flexible gap adjustment.
Cabling: 1.0-meter (3.3 ft) integral cable terminating in a gold-plated ClickLoc™ miniature coaxial connector.
Material Science:
Probe Tip: High-performance Polyphenylene Sulfide (PPS) for maximum dielectric strength and chemical resistance.
Probe Body: Corrosion-resistant AISI 303 or 304 Stainless Steel (SST).
Performance Metrics:
Linear Range: 2.0 mm (80 mils), typically calibrated at 200 mV/mil (7.87 V/mm) sensitivity.
Operating Temp: Rated for continuous operation from -51 °C to +177 °C.
Global Compliance: Multiple agency approvals (05 Suffix) including CSA, ATEX, and IECEx for Intrinsic Safety (Ex ia) and Non-Incendive (Ex nA) applications.
Key Features
ClickLoc™ Interlock System: Features a proprietary miniature coaxial connector with a positive locking mechanism that prevents signal loss or cable disconnection due to machinery vibration.
Enhanced Linear Range: Offers consistent 80-mil performance, making it ideal for monitoring radial vibration, axial thrust position, and speed sensing (Keyphasor) on turbines and compressors.
Metric Standardization: Specifically designed for equipment manufactured to metric specifications, ensuring a perfect fit without the need for thread adapters.
Environmental Sealing: The PPS tip and stainless steel body are bonded to withstand high-pressure environments (up to 50 psi) and resist degradation from synthetic lubricants.
Backward Compatibility: Fully interchangeable with standard 3300 series 8 mm systems, though optimal performance is achieved when paired with 3300 XL Proximitors and extension cables.
