Critical Temperature Note: Exposing the probe to temperatures below -34°C (-30°F) for a sustained period may cause premature pressure seal failure.

Pressure Sealing Material: Viton O-ring (seals differential pressure between probe tip and case).

FluidLoc Cable Feature

The Bently Nevada 330907-05-30-10-12-CN includes the FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable interior. Machine casings that contain pressurized oil benefit greatly from this feature. Turbine and compressor applications often require FluidLoc for environmental compliance. Without FluidLoc, oil could migrate along the cable strands and leak externally. Consequently, this probe meets strict emission control requirements. The FluidLoc design maintains the same electrical performance as standard cables. Therefore, no compromise in signal quality occurs.

Key Features of 330907-05-30-10-12-CN

The Bently Nevada 330907-05-30-10-12-CN offers increased chemical resistance compared to the 3300 RAM probe. Consequently, this probe suits many process compressor applications. Side-view characteristics are superior to those of the 3000-series 190 probe. This improvement applies when gapping the probe at the same distance from the target. All components feature gold-plated brass ClickLoc connectors. These connectors lock into place securely. Therefore, connections cannot loosen due to vibration. The patented TipLoc molding method provides a robust bond between probe tip and probe body. The reverse mount configuration with M10x1 threads suits metric mounting requirements.

Installation Guidelines for 330907-05-30-10-12-CN

Before starting, disconnect all power to your monitoring system. Prepare the mounting hole with M10x1 threads. Ensure thread engagement does not exceed 15 mm. Apply recommended torque of 7.5 N•m (66 in•lb). Do not exceed the maximum rated torque of 22.6 N•m. Connect the miniature coaxial ClickLoc connector until it locks into place. The FluidLoc sealing mechanism activates automatically upon proper connection. Verify the connection is secure and cannot loosen. Set the probe gap to the recommended 1.0 mm (40 mils). For field wiring, use three-conductor shielded triad cable. Keep wiring length under 305 meters (1,000 feet) for optimal signal quality. Finally, verify the output voltage falls within the -1 to -13 Vdc range at proper gap.

Application Scenarios for 330907-05-30-10-12-CN

Process compressors benefit from this probe's increased chemical resistance. The Bently Nevada 330907-05-30-10-12-CN monitors shaft vibration and position in pressurized machines. Reverse mount configuration suits tight installation spaces. High temperature applications up to 177°C are well supported. For sustained low temperature operation below -34°C, exercise caution. The Viton O-ring provides excellent pressure sealing against differential pressure. Consequently, this probe is ideal for compressor casing penetrations. The FluidLoc cable prevents oil migration along the cable strands. Therefore, environmental compliance is maintained even with pressurized lubrication systems.
