330173-00-03-10-02-CN Bently Nevada 3300 5mm Probe M8

Product Overview: Bently Nevada 330173-00-03-10-02-CN

The Bently Nevada 330173-00-03-10-02-CN is a 3300 series 5mm proximity probe engineered for exact displacement and vibration measurement in rotating machinery. As a maintenance engineer, you need reliable, repeatable data to protect critical assets. This probe delivers engineering-grade precision with its M8 x 1 thread, 30mm case length, and 1.0 metre total length. The miniature coaxial ClickLoc connector ensures secure, low-noise signal transmission. With a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case, it withstands harsh industrial environments.

Technical Specifications of the 330173-00-03-10-02-CN

• Input Voltage: -17.5 Vdc to -26 Vdc at 12 mA maximum
• Output Resistance: 50 Ω
• Probe DC Resistance: 7.59 ± 0.50 Ω at 1.0 m
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Probe Case Material: AISI 304 stainless steel
• Total Length: 1.0 metre (3.3 feet)
• Weight: 0.323 kg
• Connector: Miniature coaxial ClickLoc, standard cable
• Temperature Range: -35°C to +177°C
• Cable Bend Radius: 25.4 mm minimum

Note: Operation at a more positive voltage than -23.5 Vdc can reduce linear range. The probe's low sensitivity to input voltage changes (less than 2 mV per volt) ensures stable measurements.

Installation and Setup for Reliable Service

Proper installation is critical for accurate data. First, verify the target material is AISI 4140 steel and set the gap to 1.27 mm (50 mils) for standard calibration. Use the recommended probe case torque of 5.1 N·m (45 in·lb) and never exceed 7.3 N·m (65 in·lb). The M8 x 1 thread engagement should not exceed 12 mm. Maintain a minimum cable bend radius of 25.4 mm to prevent damage. The ClickLoc connector provides a secure, tool-free connection. Always follow the manufacturer's safety manual for hazardous area installations.

Maintenance and Reliability Best Practices

From a maintenance engineer's perspective, periodic inspection is essential. Check the probe tip for wear or contamination, as PPS can degrade in abrasive environments. Verify cable integrity and connector torque. The probe operates from -35°C to +177°C; exposure below -34°C may cause premature pressure seal failure. For 60 Hz magnetic fields up to 300 Gauss, the probe contributes minimal error (e.g., 0.0014 mil pp/gauss at 50 mil gap). This reliability translates to reduced downtime and extended service life.
