The 330101-35-62-10-01-05 is a classic 8mm eddy current displacement sensor probe from Bentley Nevada's 3300 XL series. This model fully complies with the American Petroleum Institute (API) 670 industrial standard and is used for non-contact, high-precision measurement of static displacement and dynamic vibration of axes.
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.

When using the 330101-35-62-10-01-05 probe, the core focus lies in "smooth deep-hole insertion, intrinsically safe compliance, and coaxial impedance protection". First, given its deep-hole design featuring a 3.5-inch unthreaded length and 6.2-inch overall length, you must ensure it passes smoothly through thick walls with at least 3mm of metal-free clearance around the tip, using a multimeter to precisely calibrate the initial gap to the center voltage. Meanwhile, as the probe comes with a 1.0-meter integrated cable, you must strictly maintain a bending radius greater than 25.4 mm during routing, absolutely forbid cutting or splicing the signal wire, and because it carries agency approvals, it must be paired with intrinsically safe Proximitors in hazardous areas with the integrated connector protector tightly locked and sealed to thoroughly eliminate impedance mismatch, intrinsic safety failures, and oil or electromagnetic interference.
It is a 3300 XL series 8mm English standard proximity probe manufactured by Bently Nevada.
What are the specific measurement applications of 330101-35-62-10-01-05 on machinery?
It is primarily used for precise, high-sensitivity measurements of radial runout and axial float of rotating metal shafts.
How do you use a deep-hole mounting probe product like 330101-35-62-10-01-05?
Technicians need to insert and screw the probe into the thick-walled bearing housing of rotating machinery via its threads.
What is the recommended gap voltage for 330101-35-62-10-01-05 during on-site installation?
While the rotating machinery is at rest, technicians testing the Proximitor output with a digital multimeter are recommended to calibrate the probe's initial position to the linear range midpoint voltage, which is around the standard -10 VDC.
In which major industrial sectors can the 330101-35-62-10-01-05 be used?
It is widely used in heavy industrial sectors such as oil and gas exploration, petroleum refineries, large petrochemical ethylene plants, thermal and nuclear power plant conventional islands, metallurgy, and large oxygen-producing air separation plants.
