FluidLoc Cable Feature

The Bently Nevada 330730-080-10-00 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 cable meets strict emission control requirements. The FluidLoc design maintains the same electrical performance as standard cables. Therefore, no compromise in signal quality occurs.

Probe System Compatibility

The 3300 XL 11 mm probe comes in various probe case configurations. Armored and unarmored options include 1/2-20, 5/8-18, M14 x 1.5, and M16 x 1.5 threads. The reverse mount 3300 XL 11 mm probe uses 3/8-24 or M10 x 1 threads. All transducer system components feature gold-plated brass ClickLoc connectors. These connectors lock into place securely. Consequently, vibration cannot loosen the connection. The patented TipLoc molding method bonds the probe tip to the probe body robustly. Additionally, the CableLoc design provides 330 N (75 lb) pull strength for secure cable attachment.

Connector Protection Options

Connector protectors provide additional protection in humid or moist environments. These protectors are recommended for all installations. For basic moisture protection, silicone tape is provided with each extension cable. However, silicone tape is not recommended for turbine oil exposure applications. In such cases, use connector protectors instead. The Bently Nevada 330730-080-10-00 with FluidLoc is fully compatible with both protection methods.

Field Wiring Guidelines

Use 0.2 to 1.5 mm² (16 to 24 AWG) wire for field connections. With ferrules, use 0.25 to 0.75 mm² (18 to 23 AWG). Three-conductor shielded triad cable is recommended for field wiring. Maximum field wiring length is 305 meters (1,000 feet) between Proximitor Sensor and monitor. For high frequency applications, consult the frequency response graphs. Signal rolloff occurs at high frequencies with longer field wiring lengths.

Linear Range and Gap Setting

For the complete 3300 XL 11 mm system, the linear range is 4.0 mm (160 mils). This range begins at approximately 0.5 mm (20 mils) from the target. Full linear range extends from 0.5 to 4.5 mm (20 to 180 mils). Output voltage corresponds to approximately -1 to -17 Vdc. Extended Deviation from Straight Line (DSL) range reaches 0.5 to 5.0 mm (20 to 200 mils). This corresponds to -1 to -19 Vdc output. Notably, the extended DSL range is not applicable with zener barriers. Recommended gap setting is 2.5 mm (100 mils).

Installation Guidelines for 330730-080-10-00

Before starting, disconnect all power to the monitoring system. Connect one end of the Bently Nevada 330730-080-10-00 to your 3300 XL 11 mm probe. Ensure the ClickLoc connector locks firmly into place. The FluidLoc sealing mechanism activates automatically upon proper connection. Then, connect the other end to the Proximitor Sensor. For machine casing penetrations, verify the FluidLoc seal is properly seated. This prevents any oil leakage along the cable. If operating in humid environments, install connector protectors. Alternatively, use the provided silicone tape for basic moisture protection. Avoid silicone tape in turbine oil exposure applications. Verify the total system length (probe + extension cable) matches your Proximitor Sensor calibration.

Application Scenarios for 330730-080-10-00

The Bently Nevada 330730-080-10-00 extends 3300 XL 11 mm probes in turbomachinery monitoring. Steam turbines with pressurized bearing housings require FluidLoc for oil containment. Gas turbines in power plants benefit from its leak prevention capability. Compressors in refineries use this cable to meet environmental emission standards. The 8.0 meter length allows Proximitor Sensors to mount in safe areas away from machines. Consequently, maintenance access improves without entering hazardous zones. The FEP insulation resists chemicals and high temperatures up to 177°C. Therefore, this extension cable suits demanding industrial environments with oil exposure risks.
