Quick Detail

Description

The 3300 XL 11 mm probe is a high-performance proximity transducer system specifically engineered for precise, non-contact vibration and displacement measurements on fluid film bearing machinery. With an impressive output of 3.94 V/mm (100 mV/mil), this transducer system ensures reliable and accurate monitoring in demanding industrial environments. The larger 11 mm probe tip provides a significantly extended linear range, offering enhanced measurement capability over the standard 3300 XL 8 mm probes, making it ideal for applications requiring long-range linear response.

Primary applications for the 3300 XL 11 mm probe include axial (thrust) position monitoring, ramp differential expansion measurements on steam turbines, rod position or rod drop evaluation on reciprocating compressors, tachometer and zero-speed detection, and phase reference (Keyphasor) signal generation. Its design is fully compatible with replacing legacy 7200-series 11 mm and 14 mm transducer systems. When upgrading to the 3300 XL 11 mm probe, all system components must be replaced to maintain optimal functionality, and monitoring systems may require software or hardware updates, such as those involving the 3500 Monitoring System. Professional guidance from local sales or service representatives is recommended to ensure seamless integration.

The 3300 XL 11 mm probe is available in multiple probe case configurations, including both armored and unarmored options, with thread sizes of ½-20, 5⁄8-18, M14 x 1.5, and M16 x 1.5. Reverse mount versions feature standard 3⁄8-24 or M10 x 1 threads. All transducer system components utilize gold-plated brass ClickLoc connectors, which secure connections and prevent loosening. The patented TipLoc molding method ensures a strong and reliable bond between the probe tip and body, while the CableLoc design provides 330 N (75 lb) pull strength for the probe cable.

Optional features include the FluidLoc cable, preventing leakage of oil or other liquids through the cable interior, and connector protectors, enhancing environmental durability in humid or wet conditions. Each 3300 XL 11 mm probe is also supplied with a locknut featuring pre-drilled safety wire holes, further improving installation reliability. Designed for durability, precision, and ease of integration, the 3300 XL 11 mm probe remains the preferred choice for critical machinery monitoring in challenging industrial applications.

Applications

The 330400-02-05 Accelerometer is a high-precision sensor designed for reliable vibration and motion measurement in industrial machinery, offering exceptional sensitivity and durability. With an impedance of approximately 50 Ohms and a voltage rating of ≤30 V DC, this accelerometer is suitable for both low- and high-energy applications, ensuring accurate detection of dynamic mechanical events across a wide frequency range. Operating temperatures between -40°C and +85°C enable the 330400-02-05 accelerometer to perform consistently in harsh and extreme environments.

This accelerometer is primarily used in applications that require precise monitoring of machine vibrations, structural dynamics, and motion profiles, including:

Rotating machinery monitoring: Measurement of bearing vibration, shaft oscillation, and rotor dynamics to prevent mechanical failures and improve maintenance planning.

Structural health monitoring: Detection of stress, displacement, and resonance in industrial frameworks, including turbines, compressors, and pumps.

Reciprocating equipment analysis: Rod motion, cylinder vibration, and piston displacement monitoring in reciprocating compressors or engines.

Condition-based maintenance systems: Integration with monitoring systems to provide early warning of abnormal vibration, aiding predictive maintenance strategies.

Process control and safety applications: Real-time feedback for tachometer measurements, zero-speed detection, and phase reference signals to ensure reliable operation in automated machinery.

The 330400-02-05 accelerometer comes in a compact 2-inch overall case length, with a total cable length of 1.0 meter (3.3 feet) and a miniature coaxial ClickLoc connector, providing secure and reliable connections. Its robust design includes dual-layer shielding (foil + braided) for superior EMI/RFI protection and a recommended minimum bend radius of 10 times the cable diameter, preventing signal interference or mechanical stress during installation.

Optional features, such as armored or unarmored mounting, allow flexibility for field installation, while the absence of agency approval requirements makes it suitable for a wide range of industrial environments. This accelerometer is engineered to deliver long-term reliability, high accuracy, and ease of integration into complex monitoring systems, making the 330400-02-05 accelerometer an essential tool for vibration analysis, machine diagnostics, and advanced condition monitoring applications.
