Bently Nevada 330901-00-79-05-02-00 7.9-inch Extended Case Probe

Product Overview

The Bently Nevada 330901-00-79-05-02-00 is a high-precision 3300 NSv (Narrow Side view) Proximity Probe engineered for applications where space is limited and a smaller probe footprint is required. This model is configured with a 1/4-28 UNF thread and an overall case length of 7.9 inches. It utilizes a 0.5-meter standard FEP-insulated coaxial cable terminated with a ClickLoc miniature coaxial connector. Designed for rugged industrial environments, the probe features a stainless steel case and a Polyphenylene sulfide (PPS) tip, providing reliable vibration and position monitoring. Depending on the specific option selection, the unit weight ranges from 14 to 150 g (0.5 to 5.3 oz).

Technical Specifications

Engineering Advantages

• Advanced Material Durability: The AISI304 stainless steel body and PPS tip ensure chemical resistance and structural integrity, while the FEP-insulated cable provides stable signal transmission.
• Optimized Weight and Form: At a maximum weight of 150 g, this probe is designed for minimal mechanical interference while maintaining the robustness needed for industrial machinery protection.
• ClickLoc™ Connectivity: Features the ClickLoc miniature coaxial connector for secure, vibration-resistant connections that prevent accidental decoupling.

Installation & Maintenance

For the 330901-00-79-05-02-00, the maximum thread engagement is 0.375 inches. During installation, the recommended torque for the 1/4-28 probe case is 5.1 N•m (45 in•lb) to prevent damage to the threads or the internal pressure seal. While the probe weighs up to 150 g, its delicate coaxial center conductor requires careful handling. Ensure the Viton O-ring is properly seated if the application involves differential pressure between the tip and the case.

Technical FAQs

Q1: What is the DC resistance of this 0.5-meter probe?
A1: The resistance from the center conductor to the outer conductor (RPROBE) for the 0.5m version is 4.0 ± 0.5 ohms.

Q2: Can this probe be exposed to sub-zero temperatures?
A2: Yes, it is rated down to -52°C. however, sustaining temperatures below -34°C (-30°F) for long periods may affect the long-term reliability of the pressure seal.

Q3: What is the weight of the Bently Nevada 330901 probe?
A3: The probe weight varies by configuration from 14 g up to approximately 150 g (5.3 oz) for longer case and cable options.
