Product Overview: Bently Nevada 330171-00-30-10-02-00
The Bently Nevada 330171-00-30-10-02-00 is a 5mm proximity probe engineered for exact displacement and vibration measurement in rotating machinery. As part of the 3300 series, this probe features a 1/4-28 UNF thread and a 1.0 metre total length. Consequently, it integrates seamlessly into turbine supervisory systems where engineering-grade precision is mandatory.
Manufactured in the U.S.A., this probe uses a polyphenylene sulfide (PPS) tip and an AISI 304 stainless steel case. The miniature coaxial ClickLoc connector ensures a verified, secure interface with extension cables. Therefore, the 330171-00-30-10-02-00 delivers reliable performance in harsh industrial environments.
Key Specifications of the 330171-00-30-10-02-00
- 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.
- Isolation: Not specified; refer to official datasheet.
- Total Length: 1.0 metre (3.3 feet).
- Case Length: 3 inches.
- Thread: 1/4-28 UNF, maximum engagement 0.375 in.
- Weight: 0.323 kg.
Precise electrical specifications are critical. The probe requires a negative supply voltage; operation above -23.5 Vdc may reduce linear range. Additionally, sensitivity is less than 2 mV change per volt input variation, ensuring stable output.
Comparison with Similar Probes
- 330171-00-30-10-02-00 (this model): 5mm tip, 1/4-28 UNF thread, 1.0 m cable, ClickLoc connector, no armor.
- 330171-00-30-10-02-05: Same but 5.0 m cable length.
- 330171-00-30-10-02-09: Same but 9.0 m cable length.
- 330171-00-30-10-02-00 with armor: Adds stainless steel armor for mechanical protection.
Unlike armored variants, this probe is lighter and more flexible, suiting tight installations. However, it lacks the abrasion resistance of armored versions. Therefore, select based on environmental exposure.
Installation and Setup
Mount the probe using a 1/4-28 UNF threaded hole. A #3 or larger tap drill is recommended for drilling and tapping. Apply a recommended torque of 5.1 N·m (45 in·lb) to the probe case; do not exceed 7.3 N·m (65 in·lb). The minimum cable bend radius is 25.4 mm (1.0 in). Connect the miniature coaxial ClickLoc connector to the extension cable, ensuring the connector-to-connector torque does not exceed 0.565 N·m (0.42 ft·lbf).
Maintain a gap of 1.27 mm (50 mils) for calibration, as specifications assume this setting. Verify the power supply is -17.5 Vdc to -26 Vdc and current draw does not exceed 12 mA. Incorrect voltage can damage the probe or reduce accuracy.
Maintenance and Reliability
Inspect the probe periodically for physical damage or loose connections. The PPS tip and stainless steel case resist many industrial chemicals, but exposure to temperatures below -34°C (-30°F) may cause premature pressure seal failure. The operating temperature range is -35°C to +177°C (-31°F to +351°F). For high-temperature applications, refer to the temperature schedule for EPL Ga and Gc classifications.
Keep the cable away from sharp edges and ensure bend radius limits are respected. Since the probe has no moving parts, wear is minimal. However, the connector interface should be checked for corrosion or tightness. Regular calibration verification ensures ongoing engineering-grade precision.
