330174-00-06-10-02-00 | Bently Nevada 5mm Probe M8 Armored

Problem: Unreliable Shaft Vibration Data in Harsh Environments

Industrial turbines and compressors operate under extreme mechanical stress. Consequently, standard proximity probes often fail prematurely due to abrasion, chemical exposure, or electrical interference. The Bently Nevada 330174-00-06-10-02-00 solves this by combining a 5 mm probe tip with a robust AISI 304 stainless steel case and integrated armor. This engineering-grade design ensures exact displacement measurements even in high-temperature zones up to +177°C.

Solution: 330174-00-06-10-02-00 Key Specifications

This probe delivers verified performance for critical machinery protection. The following parameters define its operational envelope:

• Input Voltage: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption.
• Output Resistance: 50 Ω for stable signal transmission.
• Probe DC Resistance: 7.59 ± 0.50 Ω from center to outer conductor.
• Isolation: Not specified; refer to official datasheet for isolation details.
• Total Length: 1.0 metre (3.3 feet) with 60 mm overall case length.
• Thread: M8 x 1 with 12 mm maximum thread engagement.
• Connector: Miniature coaxial ClickLoc, standard cable.

Furthermore, the polyphenylene sulfide (PPS) tip resists wear, while the 75 Ω triaxial FEP cable minimizes signal loss. Each unit weighs 0.323 Kg and offers a tensile strength of 222 N for case-to-lead connections.

Installation and Integration for 330174-00-06-10-02-00

Proper installation ensures accurate data. First, verify the target is AISI 4140 steel and gap the probe at 1.27 mm (50 mils). Then, apply a recommended torque of 5.1 N·m (45 in·lb) to the probe case, never exceeding 7.3 N·m (65 in·lb). Also, maintain a minimum cable bend radius of 25.4 mm (1.0 in) to prevent damage. Because the connector is a miniature coaxial ClickLoc, integration with 3300 series monitors is straightforward. However, for fieldbus networks, an external gateway may be required. Contact AutoDCSTech for precise matching of cables and gateways.

Maintenance and Reliability

Regular inspection extends probe life. Check for mechanical wear on the armor and tip every six months. Additionally, monitor for temperature excursions beyond -35°C to +177°C, as exposure below -34°C may cause premature seal failure. The 60 Hz magnetic field sensitivity is low (0.0004 mil pp/gauss at 10 mil gap), ensuring reliable readings near electrical equipment. By following these guidelines, you minimize downtime and maintain engineering-grade precision.
