Product Introduction
The Bently Nevada 330180-X1-05 is a 3300 XL Proximitor Sensor – the driver/demodulator for the 3300 XL 8 mm proximity probe system. It supplies radio frequency (RF) excitation to a compatible 3300 XL 8 mm probe, demodulates the probe’s output, and provides a linear analog voltage proportional to the gap between the probe tip and the shaft. The -X1 suffix typically indicates a special configuration (e.g., metal housing or enhanced shielding), while -05 denotes hazardous area approvals (ATEX, CSA, IECEx Zone 0/1/2, gas and dust). The 143416-42 is a matching extension cable (typically 4.2 meters / 13.8 ft) that connects the Proximitor to the probe. Together, they form a complete 3300 XL proximity transducer system for non‑contact vibration and position monitoring.

Application Scenarios
Hazardous Area Machinery Monitoring – Installed on turbines, compressors, and pumps in refineries, petrochemical plants, and offshore platforms where explosive gases or dust are present. The -05 approval ensures compliance with strict safety regulations.
Radial Vibration and Axial Position – Forms a complete 3300 XL system with an 8 mm probe to measure shaft‑relative vibration and thrust position on steam turbines, gas turbines, large motors, and gearboxes.
Extended Cable Run (4.2 m) – The 143416-42 extension allows the Proximitor to be mounted in a safe, accessible area (e.g., a junction box or control cabinet) while the probe remains close to the rotating shaft. This length provides flexibility for medium‑distance installations.
Keyphasor / Speed Reference – Delivers a precise once‑per‑revolution pulse for phase measurement, enabling Bode plots, orbit analysis, and overspeed detection.
Retrofit of Legacy Systems – Upgrades older 3300 (non‑XL) or 7200 systems with improved linearity, temperature range, and corrosion resistance, while maintaining compatibility with existing probe mounting holes and target surfaces.
