Quick Detail

Description

The 330708-00-20-50-02-05 3300 XL 11 mm Proximity Probe is an advanced non-contact transducer system engineered for precise vibration and displacement monitoring in industrial automation applications. Delivering a high-sensitivity output of 3.94 V/mm (100 mV/mil), this 11 mm probe provides a significantly extended linear measurement range compared to the 3300 XL 8 mm series, making it ideal for axial thrust position, ramp differential expansion on steam turbines, reciprocating compressor rod position, tachometer, zero-speed detection, and Keyphasor phase reference applications. The probe’s rugged design includes a 5/8-18 UNF threaded case, gold-plated ClickLoc connectors, patented TipLoc molding, and CableLoc cable retention, offering 330 N pull strength. The system supports armored and unarmored configurations, optional FluidLoc cable sealing to prevent oil leakage, and connector protectors for enhanced environmental resistance. Rated IP67 and capable of operating from -40°C to +85°C, the 3300 XL 11 mm Proximity Probe ensures reliable performance under harsh industrial conditions. Compatible with 3500 and updated 3300 monitoring systems, it fully replaces 7200-series 11 mm and 14 mm transducers, delivering superior accuracy and longevity in critical automation monitoring tasks.

Applications

The 3300 XL 11 mm Proximity Probe is widely used in high-precision automation monitoring environments. It excels in fluid-film bearing machines where extended linear range measurements are critical. Key applications include axial thrust position detection in turbines, differential expansion monitoring for steam energy systems, rod drop and rod position tracking in reciprocating compressors, and providing phase reference signals (Keyphasor) for rotor dynamics analysis. Additionally, its tachometer and zero-speed monitoring capability support real-time rotational speed control and protection in industrial machinery, enabling predictive maintenance and reducing unscheduled downtime. This makes it indispensable in power generation, petrochemical, and heavy manufacturing automation setups.

Specifications

Competitive Advantage

The 3300 XL 11 mm Proximity Probe offers a distinct competitive advantage by combining precision, durability, and versatility. Its extended 11 mm tip allows a longer linear range than standard 8 mm probes, delivering accurate measurements in challenging automation scenarios. The robust design, featuring TipLoc molding, CableLoc retention, and gold-plated ClickLoc connectors, ensures secure connections and exceptional reliability under harsh industrial conditions. The optional FluidLoc cable and connector protectors enhance environmental resistance, preventing oil ingress and moisture damage. Full compatibility with 3500 and upgraded 3300 monitoring systems allows seamless integration and replacement of legacy 7200-series probes, ensuring minimal system downtime and cost-effective upgrades. The probe’s IP67 rating, wide operating temperature range, and high shielding make it an optimal solution for precision vibration and displacement monitoring in industrial automation.
