Electrical & Performance Data

• Brand / Manufacturer: Bently Nevada
• Model: 330103-00-06-05-02-00
• Linear Range: 2 mm (80 mils), from 0.25 mm to 2.3 mm from target.
• Recommended Gap Setting: -9 Vdc [approximately 1.27 mm (50 mils)] for radial vibration.
• Probe DC Resistance (RPROBE): 7.45 ± 0.50 Ω (from center conductor to outer conductor).
• Frequency Response: Field wiring up to 305 meters (1000 feet) maintains signal integrity; see standard graphs for high-frequency roll-off.

Mechanical & Environmental Ratings

• Probe Tip Material: Polyphenylene sulfide (PPS) for high durability.
• Probe Case Material: AISI 303 or 304 stainless steel (SST).
• Temperature Range (Standard): Operating and storage from -52°C to +177°C (-62°F to +350°F).
• Pressure Seal: Viton® O-ring design seals differential pressure between tip and case.
• Relative Humidity: Less than 3% change in Average Scale Factor (ASF) after 56 days in 93% humidity (IEC 68-2-3).

Frequently Asked Questions (FAQ)

• What is the difference between the '05' and '17' total length options? The '05' in our suffix indicates a 0.5 meter cable, ideal for close-coupled installations. For longer runs, refer to models like the 330103-17-23-05-02-05 which features a different tip length.
• Can I use this probe in a hazardous area? Yes. When installed with intrinsic safety barriers (per drawing 141092) or galvanic isolators, it is suitable for Class I, Zone 0 and Class I, Division 1 groups.
• What tools do I need for installation? You will need standard wrenches for the M10 x 1 thread and a compatible extension cable for the ClickLoc connector.
• Does exposure to low temperatures affect performance? While the probe operates down to -52°C, exposing the pressure seal below -34°C (-30°F) may cause premature failure.
