330173-00-05-10-02-00 Bently Nevada 3300 5mm Probe M8

Problem: Reliable Shaft Vibration Measurement in Tight Spaces

Rotating machinery often presents limited mounting space and harsh conditions. The Bently Nevada 330173-00-05-10-02-00 solves this with a compact 5 mm probe tip and M8 x 1 thread. As a result, engineers can install it in confined bearing housings without compromising measurement integrity.

Solution: 330173-00-05-10-02-00 Key Specifications

This probe belongs to the Bently Nevada 3300 series. It uses a polyphenylene sulfide (PPS) tip and an AISI 304 stainless steel case. The overall case length is 50 mm, and the total length is 1.0 metre. A miniature coaxial ClickLoc connector with standard cable ensures a secure, low-noise connection.

• Input voltage: -17.5 Vdc to -26 Vdc at 12 mA maximum.
• Output resistance: 50 Ω.
• Probe DC resistance: 7.59 ± 0.50 Ω from center to outer conductor.
• Isolation: Not specified; refer to official datasheet for isolation details.
• Probe temperature range: -35°C to +177°C.
• Weight: 0.323 kg.
• Thread engagement: M8 x 1, maximum 12 mm.

Each value is verified from the manufacturer's data, ensuring engineering-grade precision for your system design.

Installation and Integration

Installation requires attention to thread engagement and cable routing. The recommended probe case torque is 5.1 N·m, with a maximum of 7.3 N·m. Furthermore, the minimum cable bend radius is 25.4 mm to prevent damage. Because the probe uses a miniature coaxial ClickLoc connector, integration with Bently Nevada 3300 series monitors is straightforward. However, for third-party systems, verify compatibility with your signal conditioner.

Maintenance and Reliability

Regular inspection of the probe tip and cable is essential. The PPS tip resists many chemicals, but exposure to temperatures below -34°C may cause premature seal failure. Therefore, avoid such conditions. Additionally, check connector torque periodically to maintain signal integrity. With proper care, the 330173-00-05-10-02-00 delivers long-term reliability in turbine and compressor applications.
