Bently Nevada 990-04-XX-01-05 165335-01 Proximity Transducer System Product Introduction, Technical Parameters, Applications and Advantages
1. Product Overview
Model: 990-04-XX-01-05 165335-01
The Bently Nevada 990-04-XX-01-05 165335-01 is an industrial proximity transducer system designed for continuous monitoring of rotating machinery operating conditions. It is mainly used for accurate measurement of shaft vibration, radial displacement, and relative shaft movement in critical rotating equipment.
This model belongs to the 990 Series Proximity Transducer System product family. The series is designed for machinery condition monitoring applications where reliable shaft measurement, stable signal performance, and long-term operation are required.
The 990-04-XX-01-05 165335-01 uses eddy current non-contact sensing technology. The system measures the distance between the probe tip and the rotating shaft surface by detecting changes in electromagnetic fields. Since the probe does not physically contact the rotating component, it provides excellent durability and measurement stability.
The product is commonly installed on industrial rotating equipment such as turbines, compressors, pumps, motors, and generators. It provides important information about rotor behavior and helps users detect abnormal operating conditions before serious mechanical failures occur.
The product is suitable for machinery protection systems, predictive maintenance programs, and continuous condition monitoring applications.

4. Product Description
The 990-04-XX-01-05 165335-01 is a precision proximity transducer system designed to provide reliable shaft movement measurement.
The product configuration includes a proximity probe and associated cable assembly. The “XX” designation represents configuration options within the product family, allowing different installation requirements to be supported.
The system directly measures shaft movement rather than only measuring external machine casing vibration.
This allows the product to provide detailed information about:
- Rotor vibration
- Shaft displacement
- Mechanical stability
- Rotating component behavior
The product is especially suitable for high-speed rotating equipment where accurate shaft condition information is necessary.
Its compact design and reliable sensing technology allow it to operate in demanding industrial environments.
5. Working Principle
The 990-04-XX-01-05 165335-01 operates using eddy current measurement technology.
The proximity probe generates an electromagnetic field near the rotating shaft surface.
When the shaft moves relative to the probe, the distance change modifies the electromagnetic field characteristics.
The system converts these changes into electrical signals representing shaft movement.
The monitoring system uses these signals to analyze:
- Vibration amplitude
- Rotor displacement
- Mechanical condition
- Equipment operating stability
The non-contact sensing principle provides:
- No physical wear on rotating components
- High measurement repeatability
- Stable long-term operation
- Reduced maintenance requirements
