3300 XL 8 mm Proximity Probe | 330102-08-15-10-02-00 | Bently Nevada

Technical Specifications

The 3300 XL 8 mm Proximity Transducer System provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements. 

Side Clearance: No other metal objects may be present within 9.5 mm (0.375 inches) of the probe head's outer perimeter.

Probe Separation: If two probes are installed side-by-side (e.g., for measuring the orthogonal X-Y vibration of the same bearing), the centerline distance between the two probe heads must be at least 40 mm (1.6 inches) to prevent electromagnetic intermodulation interference.

Linear Midpoint Setting: During initial mechanical installation adjustments, it is generally recommended to adjust the physical mounting clearance voltage between the probe and the shaft surface to approximately -10.0 Vdc (corresponding to the linear midpoint, i.e., approximately 1.27 mm/50 mils clearance).

In-depth Electrical and Signal Characteristics

Standard Target Calibration: The sensor is factory calibrated for AISI 4140 steel targets by default. If the shaft or target disc being measured is made of other materials (such as stainless steel, 45# steel, or aluminum), the output sensitivity will deviate, requiring correction of the gap voltage curve in the monitoring instrument or a custom-made preamplifier with special material calibration.

Frequency Response: Its dynamic measurement frequency range is 0 Hz to 10 kHz, accurately capturing high-frequency rotational speeds and vibration signals from a stationary state (static displacement) to tens of thousands of revolutions per minute.

Technical FAQ

Q: What is the total built-in cable length of the probe?

A: Option 10 represents a total integral probe cable length of 1.0 meter (3.3 feet).

Q: What cable and connector technology is represented by option “02” in the 330102-08-15-10-02-00 model?

A: 02 represents a cable equipped with a standard Miniature coaxial ClickLoc connector and a standard coaxial cable (without an additional connector protector).

Q: What explosion-proof qualification is provided by the final option “00” in the 330102-08-15-10-02-00?

A: 00 represents that no specific agency explosion-proof certification is required (Not required), and it is commonly used in non-explosion-proof factory areas with non-intrinsically safe system circuits.

Q: What mechanical protection housing and thread specification are provided for this 330102-08-15-10-02-00 model?

A: A stainless steel braided armor (Armor) protective outer sheath is factory supplied with the basic model (330102), and a standard 3/8-24 UNF imperial thread is used as the mechanical mounting specification.
