330173-00-04-10-02-00 Bently Nevada 5mm Probe M8x1

What Is the Bently Nevada 330173-00-04-10-02-00?

The Bently Nevada 330173-00-04-10-02-00 is a 3300 series 5 mm proximity probe engineered for precise displacement and vibration measurement in industrial machinery protection systems. Specifically, this model features an M8 x 1 thread, a 40 mm overall case length, and a 1.0 metre total length. It is manufactured in the U.S.A. and terminates with a miniature coaxial ClickLoc connector for secure signal transmission.

Because the probe operates on a -24 Vdc power supply with a 10 kΩ load, it delivers reliable performance when paired with compatible Bently Nevada transducers. The probe tip is constructed from polyphenylene sulfide (PPS), while the case uses AISI 304 stainless steel for durability in harsh environments.

Key Specifications

• Input Voltage: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption.
• Output Resistance: 50 Ω.
• Probe DC Resistance: 7.59 ± 0.50 Ω from center conductor to outer conductor.
• Total Length: 1.0 metre (3.3 feet).
• Weight: 0.323 kg.
• Connector: Miniature coaxial ClickLoc, standard cable.
• Thread: M8 x 1, maximum thread engagement 12 mm.
• Probe Tip Material: Polyphenylene sulfide (PPS).
• Probe Case Material: AISI 304 stainless steel.

Performance and Reliability

The 330173-00-04-10-02-00 operates within a probe temperature range of -35°C to +177°C (-31°F to +351°F). However, exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe exhibits excellent immunity to 60 Hz magnetic fields, with output voltage changes as low as 0.0004 mil pp/gauss at a 10 mil gap. This ensures accurate readings even in electrically noisy industrial environments.

With a recommended probe case torque of 5.1 N·m (45 in·lb) and a maximum of 7.3 N·m (65 in·lb), installation is straightforward and secure. The minimum cable bend radius is 25.4 mm (1.0 in), which prevents damage during routing.

Applications and Compatibility

This probe is ideal for continuous monitoring of radial vibration, axial position, and eccentricity on rotating machinery such as steam turbines, compressors, and pumps. It integrates seamlessly with Bently Nevada 3300 series proximitor sensors and extension cables. The 5 mm probe tip diameter allows access to tight measurement locations without compromising signal fidelity.

Integration Note

When wiring into a 3300 system, ensure the ClickLoc connector is fully seated. The probe's 75 Ω triaxial cable with FEP insulation provides robust signal integrity. For specific system integration, consult Bently Nevada documentation.
