1.0m total length
with ClickLoc connector protector
hazardous area approved (CSA/ATEX/IECEx)
The 330101-51-82-10-01-05 belongs to the 3300 XL series 8mm eddy current displacement sensor probe. It is a non-contact, high-precision, and highly reliable industrial-grade sensor that converts mechanical displacement or vibration into a proportional voltage signal output by measuring the change in gap between the probe end face and the measured metal shaft.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Thermal Power
Used on the HP or IP cylinder bearing housings of 1,000 MW ultra-supercritical steam turbines. Due to the extremely thick double-shell casing and insulation, the 5.1-inch unthreaded front allows it to smoothly pass through thick walls to perform high-precision, non-contact shaft radial vibration measurements.
Nuclear Power
Deployed on turbine-driven feed pumps within nuclear power conventional island 1,000 MW units. Utilizing its high temperature stability and 8.2-inch rigid casing, it penetrates the thick-walled bearing housing to continuously monitor main shaft axial thrust displacement.
Oil Refining
Used on high-pressure heavy crude oil circulation pumps or feed pumps in hydrocracking units. Since the pump casing is extremely thick for pressure retention, the probe passes through the deep hole close to the journal bearing to safely monitor dynamic oil-film runout in flammable gas zones under its -05 explosion-proof approval.
Gas Pipeline
Installed on large gas turbines at main long-distance natural gas pipeline booster stations. Because gas turbines feature thick acoustic-thermal enclosures and heavy cast bearing housings, this ultra-long probe easily penetrates the outer wall to capture speed and Keyphaser phase signals at extreme rotational speeds.
Steel & Iron
Used on the heavy-duty centrifugal axial blower bearing housings within blast furnace air-supply systems. The ultra-long stainless steel probe case bypasses complex external cooling jackets and thick walls, providing early vibration warnings for critical bearings in highly contaminated environments full of iron dust.
When operating this probe, it must be strictly paired with a Bently Nevada 3300 XL 8mm extension cable and Proximitor sensor while ensuring the total system length is electrically matched. Due to its long 5.1-inch unthreaded length, proper extended brackets or deep-sleeve mounting must be used to strictly control the initial installation gap between the probe tip and the target shaft. Additionally, the connector protector must be securely installed to prevent oil and moisture ingress, and intrinsic safety grounding regulations must be rigidly followed when deployed in hazardous areas.
It is a Bently Nevada 3300 XL 8mm eddy current proximity probe, used to measure shaft vibration, axial displacement, or speed of large rotating machinery.
What type of cable connector does 330101-51-82-10-01-05 use?
The "01" suffix indicates it is equipped with a miniature coaxial ClickLoc connector and includes a connector protector (for water and oil resistance).
How does 330101-51-82-10-01-05 work?
It operates on the eddy current principle. A high-frequency coil in the probe tip generates an electromagnetic field. When a metallic shaft surface approaches, eddy currents are induced, causing the Proximitor output voltage to change based on the gap distance.
How should 330101-51-82-10-01-05 be installed correctly?
It is typically screwed into a probe mounting bracket on the machine's bearing housing. A voltmeter is used to measure the Proximitor's bias voltage to properly adjust the linear gap between the probe tip and the measured shaft.
What is the standard linear range of 330101-51-82-10-01-05?
As a 3300 XL 8mm probe, when used with a standard Proximitor, its linear measurement range is 2.0 mm (80 mils).
