Bently Nevada 330104-00-06-10-02-05 3300 XL 8 mm Proximity Probe

Product Overview

In rotating machinery monitoring, accurate vibration measurement is critical for preventing unplanned downtime. The Bently Nevada 330104-00-06-10-02-05, a 3300 XL 8 mm proximity probe, delivers reliable displacement data for compressors, turbines, and pumps. This probe features an M10 x 1 thread with armor, a 1.0 meter (3.3 feet) cable, and a miniature coaxial ClickLoc connector. It carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous environments.

Technical Specifications

The 330104-00-06-10-02-05 uses a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case. It seals differential pressure between the tip and case with a Viton O-ring. The probe length is 1.0 meter with a nominal DC resistance of 7.59 ± 0.50 ohms from center conductor to outer conductor. The unthreaded length is 0 mm, and the overall case length is 60 mm.

When paired with a 3300 XL Proximitor Sensor and extension cable, the system operates between +18°C and +27°C (+64°F to +80°F) at a maximum altitude of 2000 meters. It requires a -17.5 Vdc to -26 Vdc power supply (with non-incendive circuit) and delivers output resistance of 50 ohms. Sensitivity is less than 2 mV change per volt change in input voltage.

Industry Applications

This proximity probe excels in critical rotating machinery monitoring. In steam turbine trains, it measures shaft vibration and position to detect early signs of imbalance or misalignment. For centrifugal compressors in oil and gas facilities, the 330104-00-06-10-02-05 provides continuous radial vibration data, helping operators schedule maintenance before failures occur. The ATEX and IECEx approvals allow installation in potentially explosive atmospheres.

Installation Guidance

Mount the probe using the M10 x 1 threaded hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal performance. Gap the probe at 1.27 mm (50 mils) during installation. Use only 3300 XL 8 mm extension cables and Proximitor Sensors to maintain system accuracy. The ClickLoc connector simplifies cable attachment and reduces installation time.

Maintenance and Reliability

Periodically inspect the probe cable for wear, especially near the connector and armor. Verify the Viton O-ring seal integrity to maintain pressure differential capability. The stainless steel case resists corrosion in harsh environments. Regular calibration checks with a known target ensure measurement accuracy over time. For long-term reliability, follow Bently Nevada's recommended maintenance intervals.

Compatibility and Integration

The 330104-00-06-10-02-05 works exclusively with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts non-contacting 3300-series 5 mm or 8 mm probes. The system output interfaces with vibration monitoring systems, PLCs, and DCS platforms that accept analog voltage inputs. For replacement or upgrades, verify that your existing system uses 3300 XL components.

Purchasing Advice

Before ordering, confirm your required cable length and connector type. The 330104-00-06-10-02-05 includes a 1.0 meter cable with miniature coaxial ClickLoc connector.
