300103-00-05-10-02-00 | Bently Nevada 1.0m 3300 XL 8mm Proximity Probe

Introduction to the Bently Nevada 300103-00-05-10-02-00

When machine vibration threatens uptime, the 300103-00-05-10-02-00 provides precise shaft displacement data. This Bently Nevada 3300 XL 8 mm proximity probe is engineered for continuous monitoring in critical rotating machinery.

Part of the trusted 3300 XL family, this probe measures radial vibration and axial position with high accuracy. Its compact 8 mm design fits standard mounting requirements, making it a versatile choice for turbomachinery, pumps, and motors.

With a total length of 1.0 meter (3.3 feet), the 300103-00-05-10-02-00 offers convenient installation in confined spaces. The miniature coaxial ClickLoc connector ensures secure signal transmission.

Key Features and Technical Specifications

This proximity probe is built for demanding industrial environments. Its construction and electrical characteristics are optimized for reliable performance.

• Probe Tip Material: Polyphenylene sulfide (PPS) provides excellent chemical resistance and dimensional stability.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) offers corrosion resistance and mechanical strength.
• Thread Size: M10 x 1 metric thread with a maximum engagement length of 15 mm.
• DC Resistance: Nominal resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter probe.
• Linear Range: 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target, extending to 2.3 mm (90 mils).
• Recommended Gap Setting: -9 Vdc, approximately 1.27 mm (50 mils) for radial vibration measurement.
• Temperature Range: Operating and storage from -52°C to +177°C (-62°F to +350°F) for standard probes.
• Relative Humidity: Less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3 for up to 56 days.

These specifications ensure accurate and repeatable measurements, even in harsh conditions.

Applications and Use Cases

The 300103-00-05-10-02-00 is ideal for monitoring shaft vibration and position in compressors, turbines, and gearboxes. Its linear range and gap settings are well-suited for radial vibration measurements, helping detect misalignment, unbalance, and bearing wear early.

In addition, the probe's sealed design (with Viton O-ring) prevents differential pressure issues, making it suitable for applications where pressure variations occur. The probe is not pressure tested before shipment, but custom testing can be arranged through Bently Nevada's design department.

Field wiring can be extended up to 305 meters (1,000 feet) between the Proximitor Sensor and the monitor, offering flexibility in system layout. However, longer runs may affect frequency response—refer to the datasheet figures for signal rolloff.

Installation and Setup Guide

Proper installation is critical for accurate readings. Follow these general guidelines:

• Mount the probe with the M10 x 1 thread, ensuring the thread engagement does not exceed 15 mm.
• Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG). A 3-conductor shielded triad cable with tinned wires is recommended.
• For radial vibration, set the gap to approximately -9 Vdc (1.27 mm).
• Keep the probe tip clean and free from debris.

Always consult the Bently Nevada installation manual for detailed instructions specific to your machine.

Maintenance and Reliability

Regular inspection ensures long-term reliability. Check the probe cable and connector for damage, and verify the mounting integrity periodically.

Environmental factors such as temperature and humidity can affect performance. The probe is designed to withstand up to 93% humidity with minimal scale factor change, but avoid exposing it to temperatures below -34°C (-30°F) to prevent premature seal failure.

Following a routine maintenance schedule helps extend the service life of the 300103-00-05-10-02-00 and reduces unplanned downtime.

Compatibility and Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, reliable connection.

For hazardous areas, the probe can be installed with intrinsically safe zener barriers (per drawing 141092) or galvanic isolators to meet Class I, Zone 0 requirements (AEx/Ex ia IIC T5...T1 Ga). It also supports nonincendive circuits (per drawing 140979) for Class I, Zone 2 applications (AEx/Ex nA IIC T5…T1 Gc and AEx/Ex ec II C T5…T1 Gc).
