Quick Detail

Description

The Bently Nevada 330101-00-20-10-10-02-05 is a compact and highly certified variant within the industry-proven 3300 XL 8 mm Proximity Probes series. This model is engineered for machinery condition monitoring in applications where physical space is at a premium and deployment in hazardous locations is mandatory. Distinguished by its short overall case length of 2 inches and a standard total length of 1.0 meter (3.3 feet) of integrated cable, this proximity probe offers an ideal form factor for installations in tight bearing housings or on equipment with limited clearance around the mounting point. As a high-precision eddy current displacement transducer, it generates a linear voltage output precisely proportional to the gap between its sensing tip and a conductive target, enabling accurate measurement of dynamic vibration and static axial position in critical assets such as gas turbines, pumps, and high-speed motors.

Durability and safety are paramount in its design, catering to the most demanding industrial environments. The probe incorporates Bently Nevada's patented TipLoc and CableLoc technologies, which permanently bond the probe tip to the body and securely anchor the cable, respectively. This robust mechanical construction virtually eliminates common failure modes such as tip separation or cable pull-out under intense vibration and thermal cycling. The probe body is precision-machined from AISI 303 or 304 stainless steel (SST), while the sensing tip is made of resilient Polyphenylene Sulfide (PPS), providing exceptional resistance to corrosion, chemical attack, and mechanical stress. Its robust build allows it to perform reliably across an extensive operating temperature range from -60°C to +180°C (-76°F to +356°F).

Applications

This probe is perfectly suited for vibration and position monitoring on medium-sized rotating equipment such as pumps, compressors, and fans located in congested machinery skids. Its 2-inch case length allows it to fit into standard mounting holes without protruding excessively, making installation cleaner and safer in spaces where longer probes might interfere with adjacent piping, conduits, or other components.

Certified with CSA, ATEX, and IECEx approvals, this model is the go-to choice for installing new monitoring points or replacing existing probes on equipment situated in classified hazardous zones. Its compact size and robust construction make it ideal for use on fuel gas compressors, hydrocarbon pumps, or mixer drives within refineries, chemical plants, and offshore platforms, ensuring compliance with strict safety regulations without compromising on measurement accuracy.

The combination of a short body and a 1-meter integrated cable provides excellent flexibility for retrofitting condition monitoring onto existing machinery where access is limited and wiring paths are tight. It is particularly effective for adding Keyphasor reference or radial vibration measurement points to the auxiliary drives and smaller turbines within a power generation unit, enabling comprehensive monitoring without requiring major mechanical modifications.

Specifications

Competitive Advantage

1. Compact, Certified Solution for Hazardous and Space-Limited Areas

This probe uniquely combines a compact 2-inch form factor with full CSA, ATEX, and IECEx Approvals. This dual advantage allows it to be installed in physically tight spaces within certified hazardous locations—a specific requirement that many longer or uncertified probes cannot meet. It solves two common installation challenges simultaneously, providing a compliant and practical solution for critical equipment in petrochemical and oil & gas environments.

2. Unmatched Mechanical Integrity from Patented Retention Systems

The integration of patented TipLoc and CableLoc technologies delivers superior mechanical reliability. TipLoc prevents the sensing tip from loosening or separating due to vibration, while CableLoc ensures the cable assembly can withstand significant pull force without disconnecting. This directly addresses the primary causes of premature probe failure, dramatically extending service life and reducing maintenance costs and unplanned downtime.

3. High-Fidelity Signal Performance Across Extreme Conditions

Engineered to deliver a stable 50 Ω output with low supply sensitivity across an extreme operating temperature range of -60°C to +180°C, this probe guarantees consistent signal accuracy. Whether in freezing outdoor installations or high-temperature bearing housings, it provides reliable, low-noise data essential for effective vibration analysis and position monitoring, ensuring that protection systems and maintenance decisions are based on trustworthy information.
