Product Overview
When vibration monitoring systems face extreme temperatures, cable fatigue, or cross-talk interference, the Bently Nevada 330709-000-040-10-12-00 3300 XL 11 mm Proximity Probe delivers precise measurements. This probe is designed for critical rotating machinery, offering robust construction with a PPS tip and AISI 304 stainless steel case. With a 1.0-meter overall length and a miniature coaxial ClickLoc connector with FluidLoc cable, it ensures reliable signal transmission even in harsh environments.
Technical Specifications Breakdown
The Bently Nevada 330709-000-040-10-12-00 features detailed parameters that guarantee accurate performance:
-
Probe DC Resistance (RPROBE): 5.9 ± 0.5 ohms at 1.0m length, ensuring consistent electrical characteristics.
-
Temperature Range: Operating and storage from -52°C to +177°C, with extended classification for hazardous areas (EPL Ga/Gc, Dc).
-
Probe Case Torque: Maximum 63.3 N·m (560 in·lb), recommended 21.1 N·m (187 in·lb) for secure mounting.
-
Minimum Bend Radius: 25.4 mm (1.0 in) to prevent cable damage.
-
Cross-talk Limitation: Requires minimum target flat surface diameter of 30.5 mm and shaft diameter of 152 mm for accurate readings.
Installation and Setup Guidance
Proper installation of the Bently Nevada 330709-000-040-10-12-00 begins with verifying thread engagement: the M16x1.5 probe case thread allows maximum 24 mm engagement. Torque the probe case to the recommended 21.1 N·m (187 in·lb) to avoid over-stressing. The connector-to-connector torque should be finger-tight only (max 0.565 N·m). Ensure the cable does not exceed the minimum bend radius of 25.4 mm to maintain signal integrity and prevent fatigue. Use the FluidLoc cable properly to seal against moisture ingress.
Maintenance and Reliability
The Bently Nevada 330709-000-040-10-12-00 is built for low-maintenance operation in demanding conditions. Regularly inspect the probe cable for kinks or abrasions, as the FEP-insulated triaxial cable is vulnerable to sharp edges. The probe’s temperature range covers -52°C to +177°C, but exposing it below -34°C (-30°F) may cause premature seal failure; warm the probe gradually if needed. For EPL classified environments, adhere to the temperature classification schedules to maintain safety and longevity. The robust 304 stainless steel case resists corrosion, making it suitable for chemical or marine environments.
Selection Guide and Purchasing Advice
Before ordering, verify the required total length (this unit is 1.0 meter) and connector type (Miniature coaxial ClickLoc with FluidLoc cable). The Bently Nevada 330709-000-040-10-12-00 is intended for applications needing a 3300 XL 11 mm probe without armor. For custom lengths or armored versions, consult alternative part numbers. UBEST Automation (ubest101) stocks this precise model, ensuring fast delivery and genuine Bently Nevada quality. Confirm your shaft diameter meets the minimum 152 mm requirement to avoid cross-talk errors. Buying from a trusted distributor guarantees warranty support and technical assistance.
