The BENTLY NEVADA 330101-00-20-10-02-05 3300 XL 8 mm Proximity Probe is an eddy-current displacement sensor designed for high-precision vibration, position, and shaft movement monitoring in rotating machinery. Manufactured by Bently Nevada, it is part of the 3300 XL series used in critical condition monitoring systems.
This probe is engineered for installation in fluid-film bearing machines such as turbines, compressors, pumps, and motors. It measures the distance between the probe tip and a conductive target surface, converting it into an electrical signal proportional to vibration or shaft position. With a 1.0 m (3.3 ft) cable, ClickLoc connector, and robust stainless-steel housing, it is optimized for industrial environments requiring high reliability and long-term stability.
The probe is identified by part number 330101-00-20-10-02-05 and features a 3/8-24 UNF threaded, non-armored design with a total length of 1.0 m and a compact 2.0 in case length option. It uses a miniature coaxial ClickLoc connector with standard cable configuration for fast and secure installation.
It operates with a linear measurement range of 0.25 to 2.3 mm, supports a –52°C to +177°C temperature range, and requires a supply voltage of –17.5 Vdc to –26 Vdc with a maximum current consumption of 12 mA. The probe provides a 50 Ω output resistance and maintains high stability with input sensitivity variation below 2 mV/V. The sensing tip is made of Polyphenylene sulfide (PPS), while the housing is constructed from AISI 303/304 stainless steel, and the cable uses 75 Ω triaxial FEP insulation.
It is certified under CSA, ATEX, and IECEx approvals, making it suitable for hazardous industrial environments. The system also defines a recommended radial vibration clearance of approximately 1.27 mm (50 mils).
The BENTLY NEVADA 330101-00-20-10-02-05 3300 XL 8 mm Proximity Probes provides high-accuracy non-contact measurement, enabling reliable detection of shaft vibration, axial position, and mechanical displacement. Its eddy-current sensing technology ensures stable performance even in oil, steam, or high-temperature environments.
The ClickLoc connector design enhances installation speed and maintenance efficiency, reducing downtime during replacement or calibration. Its wide temperature tolerance and rugged stainless-steel construction provide excellent durability in harsh industrial conditions.
Additionally, its certified explosion-proof compliance (ATEX/IECEx) ensures safe operation in hazardous zones, while its compact design allows installation in tight mechanical spaces. The probe also delivers high linearity and signal stability, which improves diagnostic accuracy in condition monitoring systems.
This 330101-00-20-10-02-05 probe is widely used in rotating machinery condition monitoring systems, especially in industries requiring high reliability and predictive maintenance. Typical applications include:
Steam and gas turbines in power generation plants
Centrifugal compressors in oil & gas facilities
Pumps and motors in petrochemical systems
Industrial gearboxes and rotating shafts
Keyphasor reference and speed measurement systems
Vibration monitoring in critical production machinery
It is particularly effective in fluid-film bearing systems, where direct mechanical contact sensors cannot be used.
The BENTLY NEVADA 330101-00-20-10-02-05 3300 XL 8 mm Proximity Probes plays a key role in machine health monitoring and protection systems. It continuously measures shaft displacement and vibration, allowing early detection of abnormal operating conditions such as imbalance, misalignment, bearing wear, or shaft runout.
By providing real-time analog signals to monitoring systems, it enables predictive maintenance strategies, reducing unplanned downtime and preventing catastrophic equipment failure. The probe supports alarm and shutdown logic systems, which can trigger protective actions when vibration thresholds are exceeded.
Its high-resolution signal output ensures accurate trend analysis, helping operators identify gradual degradation before failure occurs. In safety-critical environments, it acts as a primary sensor for machine protection systems, ensuring operational stability and equipment integrity under harsh industrial conditions.
