Armored 5 mm Eddy-Current Probe for Machinery Vibration and Position Monitoring
The Bently Nevada 330172-00-16-05-02-05 is a 3300 5 mm Proximity Probe designed for use with the 3300 5 mm Proximity Transducer System. This system consists of a 3300 5 mm probe, a 3300 XL extension cable, and a 3300 XL Proximitor® Sensor. It provides a voltage output proportional to the distance between the probe tip and a conductive target, enabling accurate measurement of both shaft vibration and shaft position on fluid-film bearing machines.
Unlike the 330171 series, the 330172 series incorporates stainless-steel armor on the probe cable, providing additional mechanical protection in demanding industrial environments.

Key Features
Non-Contact Eddy-Current Measurement
Measures both dynamic shaft vibration and static shaft position without physical contact, reducing wear while maintaining high measurement accuracy.
Armored Probe Cable
The 330172 model includes stainless-steel armor to improve resistance against abrasion, crushing, and mechanical damage in industrial installations.
Complete Interchangeability
When used with the proper 3300 XL extension cable and 3300 XL Proximitor® Sensor, the transducer system provides factory-calibrated interchangeability without individual component matching.
API 670 Compatibility
The complete 3300 proximity transducer system is designed for machinery protection and monitoring applications commonly implemented in accordance with API 670 requirements.
Industrial Reliability
The probe provides stable performance over a wide operating temperature range and is widely used in critical rotating machinery applications requiring continuous condition monitoring.
Frequently Asked Questions
1. What is the difference between 330171 and 330172?
The 330171 uses a standard probe cable, while the 330172 features a stainless-steel armored cable for greater mechanical protection.
2. What does the "05" system length option indicate?
It specifies a 5.0 m (16.4 ft) total transducer system length (probe plus extension cable).
3. What is measured by this probe?
It measures both shaft vibration and shaft position using eddy-current sensing technology.
4. Is the probe compatible with standard 3300 XL Proximitor® Sensors?
Yes. It is designed to operate with the 3300 XL extension cable and 3300 XL Proximitor® Sensor as part of the complete 3300 5 mm transducer system.
5. What does the final "-05" option represent?
It denotes the Multiple Approvals option, including CSA, ATEX, IECEx, and other applicable certifications depending on the destination country.
