Model: 990-05-50-02-05
The Bently Nevada 990-05-50-02-05 is a compact proximity transducer system designed for continuous monitoring of rotating machinery operating conditions. It is mainly used to measure shaft vibration, radial displacement, and relative shaft movement in industrial rotating equipment.
This model belongs to the 990 Series Proximity Transducer System, which is designed for machinery condition monitoring applications requiring accurate shaft measurement, reliable signal transmission, and long-term operational stability.
The 990-05-50-02-05 adopts eddy current non-contact sensing technology. The proximity probe detects changes in the electromagnetic field between the probe tip and the rotating shaft surface. These changes are converted into electrical signals that represent shaft displacement and vibration movement.
The 5 mm compact probe design provides installation flexibility, especially for equipment where mounting space is restricted.
The product is suitable for monitoring:
The system provides important operating information for equipment protection, condition analysis, and predictive maintenance.
Bently Nevada is an industrial machinery monitoring brand specializing in rotating equipment condition monitoring, vibration measurement, and machinery protection technologies.

The product is designed for applications where accurate shaft measurement is required but available installation space is limited.
Its compact structure allows easier integration into smaller rotating machinery systems.
The 990-05-50-02-05 operates using eddy current sensing technology.
The proximity probe generates an electromagnetic field around the sensing area.
When the rotating shaft moves relative to the probe, the distance change affects the electromagnetic field.
The system converts these changes into electrical output signals proportional to shaft movement.
The monitoring equipment analyzes the signal to determine:
The non-contact measurement method provides several benefits:
