Bently Nevada 330105-02-12-50-12-CN 3300 XL Reverse Mou330105-02-12-50-12-CNnt Probe

Full Summary: The Bently Nevada 330105-02-12-50-12-CN is a 3300 XL 8mm reverse mount probe. It features a 5.0 meter total length with Miniature ClickLoc coaxial connector. This probe includes country specific approval CN for various regional requirements.

Technical Specifications

The Bently Nevada 330105-02-12-50-12-CN has a nominal probe DC resistance of 8.73 ± 0.50 Ω at 5.0 meters length. This resistance measurement goes from center conductor to outer conductor.

The probe case thread is 3/8-24 with maximum thread engagement of 0.563 inches. Probe weight measures 323 grams per meter (11.4 oz per meter). The total unit dimensions are 20.4 cm x 22.2 cm x 3.7 cm.

Standard probe temperature range spans -52°C to +177°C (-62°F to +350°F). Extended temperature range reaches -52°C to +218°C (-62°F to +425°F) for the probe tip. The probe cable and connector handle -51°C to +260°C.

Exposing this Reverse Mount Probe to temperatures below -34°C (-30°F) may cause premature pressure seal failure. The probe uses Viton O-ring sealing material for differential pressure protection. Bently Nevada does not pressure test probes prior to shipment.

Relative humidity performance shows less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC standard 68-2-3 for up to 56 days.

The connector option is Miniature ClickLoc coaxial with FluidLoc cable (-12). The FluidLoc cable is not necessary for most 330105 installations due to the probe sleeve presence. Consider your application carefully before ordering this cable option for the 330105-02-12-50-12-CN.

Hazardous Area Approvals

The Bently Nevada 330105-02-12-50-12-CN carries ia approval for intrinsically safe installations. Use with zener barriers per drawing 141092 or with galvanic isolators. Ratings include Class I, Zone 0: AEx/Ex ia IIC T5…T1 Ga. Also approved for Class 1, Groups A, B, C, D and Class II, Groups E, F, G.

nA and ec approvals apply for non-incendive circuit connections per drawing 140979. Ratings include Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Also approved for Class 1, Division 2, Groups A, B, C, D and Class I, Zone 2: AEx/Ex ec IIC T5…T1 Gc.

Temperature Schedule Information

For EPL Ga and Gc classification, T1 rating covers -55°C to +232°C ambient temperature. T2 covers -55°C to +177°C. T3 covers -55°C to +120°C. T4 covers -55°C to +80°C. T5 covers -55°C to +40°C.

For EPL Dc classification, T280°C applies at Ta -55°C to +232°C. T225°C applies at Ta -55°C to +177°C. T170°C applies at Ta -55°C to +120°C. T130°C applies at Ta -55°C to +80°C. T105°C applies at Ta -55°C to +100°C. T90°C applies at Ta -55°C to +40°C.

Installation Guidelines

Mount this reverse mount probe using the 3/8-24 thread with proper thread engagement. Do not exceed the 0.563 inch maximum thread engagement length. Ensure the probe sleeve is present before considering FluidLoc cable needs.

Avoid exposing the probe to temperatures below -34°C during operation. This prevents premature pressure seal failure. Use appropriate intrinsically safe barriers or galvanic isolators for ia approved installations.

For non-incendive installations, follow drawing 140979 for proper circuit connection. Keep the probe away from submerged conditions as pressure testing is not performed at the factory.
