330141-08-30-01-05 Bently Nevada 8 mm Probe 3.0 m Armored

Introduction: The Evolution of Precision Measurement

For decades, industrial machinery has grown faster, hotter, and more demanding. Consequently, vibration monitoring has evolved from simple observation to engineering-grade precision. Early proximity probes often failed under extreme conditions, causing costly downtime. Therefore, Bently Nevada developed the 3300 XL series to meet these challenges. The 330141-08-30-01-05 is a direct result of that evolution. It combines a rugged 8 mm probe tip with a 3.0-meter armored cable. This design ensures exact measurement in the harshest environments. As a result, engineers can trust this probe for critical turbomachinery protection.

330141-08-30-01-05 Key Specifications

The 330141-08-30-01-05 offers verified performance for demanding applications. Its incremental scale factor is 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems. However, this specific model uses a 3.0-meter total length. The probe features a nominal DC resistance of 8.17 ± 0.50 Ω from center to outer conductor. Furthermore, the probe tip is molded from polyphenylene sulfide (PPS) for chemical resistance. The case is constructed from AISI 303 or 304 stainless steel. This combination provides a robust barrier against physical abuse. For precise integration, the connector is a miniature coaxial ClickLoc type with protector.

Installation and Setup

Proper installation ensures accurate data and long service life. First, mount the probe securely using the armored case. The armor protects the cable from mechanical damage. Second, maintain the specified 3.0-meter total length; do not alter the cable. Third, connect the miniature coaxial ClickLoc connector carefully. The connector protector prevents accidental disconnection. Finally, verify the probe's DC resistance to confirm integrity. Always follow the manufacturer's safety manual for wiring and configuration.

Maintenance and Reliability

Routine inspection is essential for reliable operation. Periodically check the armored cable for wear or abrasion. Additionally, inspect the probe tip for buildup or damage. The operating temperature range for the standard probe is -52°C to +177°C. However, exposing the probe below -34°C may cause premature seal failure. Therefore, avoid extreme cold during storage or installation. The Viton® O-ring seals differential pressure between tip and case. Remember, probes are not pressure tested prior to shipment. For engineering-grade precision, verify all parameters before commissioning.
