Quick Detail

Description

The 330105-02-12-10-12-05 is a high-performance displacement sensor within the specialized 3300 XL 8 mm Reverse Mount Probes series. As a cornerstone of Bently Nevada’s eddy current transducer systems, this probe is specifically engineered for "reverse mount" scenarios where traditional front-mount probes cannot be utilized. In the 3300 XL 8 mm Reverse Mount Probes ecosystem, the 330105-02-12-10-12-05 provides an output voltage directly proportional to the gap between the probe tip and the target conductive surface, enabling precise monitoring of both static position and dynamic vibration. This makes the 3300 XL 8 mm Reverse Mount Probes indispensable for tracking shaft vibration, thrust position, and Keyphasor signals in critical rotating machinery.

The design of the 330105-02-12-10-12-05 emphasizes mechanical integrity and environmental resilience. Featuring a 60 mm (2.4 inches) overall case length and a 0 mm unthreaded portion, these 3300 XL 8 mm Reverse Mount Probes are ideal for flush-mount applications in bearing housings. The probe is equipped with a 1.0-meter FluidLoc cable, which prevents oil or other process fluids from leaking through the cable's interior, and a Miniature ClickLoc coaxial connector for secure, vibration-resistant signal transmission. Fully compliant with API 670 standards, the 3300 XL 8 mm Reverse Mount Probes ensure maximum data accuracy and thermal stability across a wide temperature range of -45°C to +165°C.

To sum up, the 3300 XL 8 mm Reverse Mount Probes stand out in the field of eddy current proximity transducers with their superior measurement performance, strict API 670 compliance, strong compatibility, and innovative reverse mount design. It is not only a reliable tool for industrial equipment condition monitoring but also a key support for improving production safety and operational efficiency, making it an indispensable core component for industries pursuing high precision, high reliability, and high efficiency.​

Applications

The 330105-02-12-10-12-05 is primarily utilized for monitoring radial vibration and axial (thrust) position in rotating machinery with restricted access. Its reverse-mount design allows it to be installed from the outside into a bearing housing or bracket, making it perfect for steam turbines, centrifugal compressors, and large pumps. The 2 mm linear range ensures that even minute shaft displacements are captured accurately, providing the essential data needed for predictive maintenance and fault diagnosis in power generation and oil and gas facilities.

This probe is highly effective for Keyphasor reference signal collection and rotational speed measurement. By detecting a notch or keyway on a rotating shaft, the 330105-02-12-10-12-05 generates a once-per-turn pulse critical for phase analysis and balancing procedures. Given its FluidLoc cable technology, it is specifically applied in oil-filled bearing housings where preventing fluid migration along the cable is a critical safety and maintenance requirement.

In hazardous and extreme-temperature environments, the 330105-02-12-10-12-05 provides a certified monitoring solution. With CSA, ATEX, and IECEx approvals, it is deployed in Zone 1/2 locations within refineries and chemical plants. Its robust AISI 303/304 stainless steel case and PPS tip allow it to function reliably at temperatures up to 165°C, ensuring continuous performance in high-heat areas near turbine stages or high-pressure reciprocating engines where standard sensors might fail.

Specifications

Competitive Advantage

Innovative Reverse Mount Architecture for Tight Spaces: The 330105-02-12-10-12-05 features a unique reverse-mount configuration that solves installation challenges in narrow cavities and compact fluid-film bearing assemblies. With a 60 mm case length and 0 mm unthreaded length, it provides a flush-profile installation that traditional probes cannot achieve, allowing for high-precision monitoring without extensive machinery modification.

Advanced FluidLoc Cable and ClickLoc Connection: This probe is equipped with a FluidLoc cable, which prevents lubricating oil or moisture from migrating through the cable's internal structure to the electronics. Combined with the Miniature ClickLoc coaxial connector, the 3300 XL 8 mm Reverse Mount Probes ensure a leak-proof, vibration-resistant link that maintains signal integrity even in the most abrasive and oil-saturated industrial environments.

Global Hazardous Area Compliance and API 670 Standards: The 330105-02-12-10-12-05 carries comprehensive CSA, ATEX, and IECEx approvals, making it "plug-and-play" for regulated global industries. By strictly adhering to API 670 standards, it guarantees exceptional linearity and interchangeability within the 3300 XL ecosystem, significantly reducing spare parts inventory complexity and lowering the total cost of ownership for industrial operators.
