Quick Detail

Description

The 330103-00-04-10-02-CN is a high-performance 3300 XL 8 mm Proximity Probe engineered for precise, non-contact displacement and vibration measurements in critical rotating machinery. As a flagship component of the 3300 XL series, this proximity probe is specifically configured with an M10 x 1 metric thread and a 0 mm unthreaded length, making it ideal for flush-mount installations in bearing housings. The 330103-00-04-10-02-CN provides a 1.0-meter total length, which is the industry standard for connecting to an extension cable within a local junction box. This 3300 XL 8 mm Proximity Probe converts the distance between the probe tip and the target shaft into a high-fidelity electrical signal, enabling the monitoring of radial vibration, axial thrust, and rotational speed.

A defining feature of the 330103-00-04-10-02-CN is its -CN agency approval, which signifies compliance with NEPSI/CCC Ex standards for hazardous area deployment in China, alongside its global CSA, ATEX, and IECEx certifications. This ensures that the 3300 XL 8 mm Proximity Probe can be safely installed in Zone 0, 1, or 2 environments where explosive gases may be present. The construction of the 330103-00-04-10-02-CN utilizes a rugged Polyphenylene Sulfide (PPS) tip and an AISI 303/304 stainless steel body, providing exceptional resistance to the corrosive lubricants and high-pressure steam often found in industrial turbines and compressors.

Applications

The 330103-00-04-10-02-CN is primarily applied in the heavy power generation and petrochemical industries for the continuous monitoring of steam and gas turbine shafts. Its 2 mm linear range allows for the precise tracking of radial vibration and axial displacement, which is critical for preventing catastrophic bearing failure. By providing a real-time signal proportional to the gap, this 3300 XL 8 mm Proximity Probe enables plant operators to detect early signs of shaft misalignment, rotor unbalance, or fluid-film bearing instability, ensuring the safe operation of multi-million dollar assets.In oil refineries and natural gas processing plants, this 3300 XL 8 mm Proximity Probe is used as a Keyphasor sensor to provide timing signals for phase measurements and rotational speed. The -CN (NEPSI/CCC Ex) and ATEX/IECEx approvals make it the preferred choice for installation directly inside explosive-proof enclosures or near compressor seals. The 1.0-meter integrated cable and ClickLoc connector facilitate easy routing through machine casings to external junction boxes, where it can be linked to the monitoring system to provide essential data for machinery diagnostics and overspeed protection.The compact 40 mm case length and 0 mm unthreaded configuration of the 330103-00-04-10-02-CN make it exceptionally suitable for retrofitting older equipment with modern vibration monitoring capabilities. It is frequently installed in centrifugal pumps, industrial blowers, and gearboxes where space within the bearing housing is limited. The Polyphenylene Sulfide (PPS) probe tip ensures that the sensor can withstand high-temperature oil baths (up to $+105^\circ\text{C}$) without degradation, providing long-term stability for predictive maintenance programs in diverse manufacturing and mining environments.

Specifications

Competitive Advantage

Dual Local and Global Hazardous Area Certification The 330103-00-04-10-02-CN stands out by offering the -CN approval suffix, meeting the specific NEPSI and CCC Ex requirements for the Chinese market. Combined with CSA, ATEX, and IECEx approvals, this allows global engineering firms to standardize on a single probe model for international projects, ensuring total regulatory compliance across different geographic regions without needing to stock multiple part variations.

Advanced Material Durability and PPS Tip Technology Equipped with a high-performance Polyphenylene Sulfide (PPS) tip and a gold-plated ClickLoc connector, this 3300 XL 8 mm Proximity Probe is built for extreme industrial resilience. The PPS material is chemically inert to most lubricants and acids, while the AISI 303/304 stainless steel case provides structural rigidity. This robust design prevents moisture ingress and tip fracture, resulting in a longer service life and fewer replacement cycles compared to standard sensors.

Total Interchangeability and API 670 Compliance A major competitive edge is the probe's strict adherence to API 670 standards, which guarantees that any 330103-00-04-10-02-CN probe is fully interchangeable with any 3300 XL extension cable and Proximitor. This eliminates the necessity for time-consuming field calibration. Maintenance teams can replace a damaged probe with a new one from stock and maintain the exact same 7.87 V/mm (200 mV/mil) sensitivity, ensuring immediate return to service and consistent data accuracy.
