330709-000-130-10-02-00 | Bently Nevada 1.0 m Probe

The Bently Nevada 330709-000-130-10-02-00 is a Probe for industrial control and automation applications.

When a compressor train at a petrochemical plant began showing erratic radial vibration readings, engineers traced the fault to a failed proximity probe. The replacement needed to match the original exactly: an 11 mm tip, M16 x 1.5 mounting thread, and a 1.0 metre cable with a miniature coaxial ClickLoc connector. The Bently Nevada 330709-000-130-10-02-00 meets those requirements as a genuine 3300 XL series probe.

What Is the 330709-000-130-10-02-00 Probe?

This Bently Nevada unit is a 3300 XL 11 mm proximity probe manufactured in the U.S.A. It carries a 130 mm overall case length with no unthreaded section and a 1.0 metre (3.3 feet) total length. The probe tip is made of polyphenylene sulfide (PPS), while the case uses AISI 304 stainless steel. The cable is 75 Ω triaxial, FEP-insulated, and terminates in a miniature coaxial ClickLoc connector. Agency approval is not required for this configuration.

Key Specifications and Their Practical Meaning

• Probe dc resistance: 5.9 ± 0.5 Ω from center conductor to outer conductor at 1.0 m length — a critical value for verifying probe integrity during commissioning.
• Probe case torque: Maximum rated 63.3 N·m (560 in·lb); recommended 21.1 N·m (187 in·lb) for M16 x 1.5 cases.
• Minimum bend radius: 25.4 mm (1.0 in) with or without stainless steel armor — important for routing in tight machine housings.
• Temperature range: Operating and storage from -52°C to +177°C (-62°F to +351°F). Exposure below -34°C (30°F) may cause premature pressure seal failure.
• Connector torque: Finger tight recommended; maximum 0.565 N·m (5 in·lb).

How Does This Probe Support Reliability Programs?

Reliability engineers rely on consistent, traceable measurements. The 3300 XL 11 mm probe delivers a linear output over its measurement range, with cross-talk limitations specified for flat targets (minimum 30.5 mm diameter) and shaft diameters (minimum 152 mm). The Viton O-ring seals differential pressure between tip and case, though probes are not pressure tested prior to shipment. For harsh environments, the 100% condensing, non-submersible rating applies when connectors are protected. These features make the probe suitable for continuous monitoring on turbines, compressors, and pumps where early fault detection protects production uptime.

Installation and Maintenance Essentials

Mount the probe using the M16 x 1.5 thread, observing the maximum thread engagement of 24 mm. Set the gap according to the monitor system requirements, and verify dc resistance at the connector. Route the cable with at least a 25.4 mm bend radius and secure it to avoid strain. Periodically inspect the probe tip for deposits and the cable for abrasion. Because the probe is not pressure tested, confirm seal integrity if the application involves differential pressure. Always follow the manufacturer’s safety manual for hazardous-area installations.
