Industry Applications for Vibration Monitoring
Its 2 mm linear range and -9 Vdc recommended gap setting allow precise measurement of shaft displacement, enabling early detection of imbalance, misalignment, or bearing wear. The stainless steel case and PPS tip withstand high temperatures and corrosive atmospheres.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For optimal signal integrity, follow the frequency response graphs in the manual to account for signal roll-off at high frequencies with longer cable runs.
Maintenance & Reliability
The probe is designed for minimal maintenance. Inspect the cable and connector periodically for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The Viton® O-ring seals differential pressure between tip and case; contact Bently Nevada if pressure testing is required.
