Introduction
The Bently Nevada 30000-00-30-18-02 is a compact probe vibration sensor designed for non-contact monitoring of rotating machinery. It belongs to the Bently Nevada proximity vibration sensor family and is intended for applications where reliable measurement of shaft movement, vibration, and machine condition is required.
With its 30 mm probe configuration and 18-inch overall length, this model provides a practical sensing arrangement for machinery installations where the probe needs a defined reach while maintaining a compact sensing head. Its non-contact operating principle allows the probe to monitor a rotating target without physical contact, making it suitable for continuous-duty machinery applications.
For maintenance departments supporting turbines, compressors, pumps, motors, generators, and other rotating equipment, the 30000 series provides a useful sensor option for established machinery-monitoring architectures. The 30000-00-30-18-02 is particularly attractive when replacement compatibility, installation simplicity, and dependable vibration measurement are important purchasing considerations.
Technical Specifications
The 30000 Series is used for proximity-based vibration and shaft-motion measurement. The complete ordering code should always be checked against the existing installation because different 30000 configurations can vary in probe length, cable arrangement, and connection details.

Applications
Turbine Vibration Monitoring
The sensor can be incorporated into turbine monitoring systems where non-contact observation of shaft movement is required. Properly positioned proximity sensing provides useful information for identifying changes in rotor behavior.
Compressor Condition Monitoring
Compressors can develop vibration associated with imbalance, misalignment, mechanical looseness, bearing conditions, or other operating changes. A dedicated proximity sensor provides a continuous measurement point for compatible monitoring equipment.
Pump Monitoring
Industrial pumps often operate continuously and may be distributed across a plant. Compact proximity sensors such as the 30000-00-30-18-02 can provide a practical sensing solution for machines where reliable vibration information is required.
Motor and Generator Applications
The sensor can be used on suitable rotating electrical machinery to observe relative shaft movement and vibration. Its non-contact measurement principle avoids physical wear at the sensing point.
Machinery Protection Systems
When combined with compatible signal-conditioning and monitoring equipment, the sensor can become part of a larger machinery-protection chain, providing vibration information for alarms, trending, and maintenance decisions.
Replacement and Retrofit Work
For facilities maintaining installed Bently Nevada equipment, an exact part-number replacement can simplify maintenance planning and help preserve the original mechanical installation arrangement.
Advantages
Non-Contact Measurement
The sensor measures the rotating target without physical contact. This eliminates mechanical wear between the sensing element and shaft and makes the technology well suited to continuous machinery operation.
Compact Probe Configuration
The 30 mm configuration provides a relatively compact sensing arrangement while maintaining the required probe reach for the intended installation.
Extended 18-Inch System Length
The 18-inch configuration provides useful flexibility when the sensor connection point is located some distance from the actual measurement position.
Suitable for Continuous Monitoring
Unlike occasional manual vibration measurements, a permanently installed probe can provide continuous data to compatible machinery-monitoring equipment.
Practical Maintenance Solution
The clearly defined part number makes it easier for maintenance teams to identify the correct replacement configuration when working on established Bently Nevada systems.
Broad Rotating-Machinery Use
The sensor can support a wide range of applications, from pumps and motors to compressors and turbine-related equipment.
Integration-Friendly Design
As part of a complete proximity-monitoring system, the probe can work with appropriate signal-conditioning and monitoring hardware to provide actionable vibration information.
Technical FAQs
