The 330105-00-32-05-02-00 belongs to the high-performance Bently Nevada 3300 XL 8mm family, specifically designed as a Reverse Mount solution. This configuration caters to specialized industrial housing requirements where the probe must be installed through the internal diameter of a mounting sleeve or housing. It plays a pivotal role in Turbine Supervisory Instrumentation (TSI), delivering non-contact displacement measurements for radial vibration and axial position monitoring.
Engineered for the most demanding rotating machinery, including steam turbines and high-pressure compressors, this probe utilizes advanced eddy current technology. The PPS (Polyphenylene Sulfide) tip and Stainless Steel case ensure the unit maintains a linear 200 mV/mil signal even when submerged in hot lubricating oil or exposed to high-velocity steam. By capturing minute shaft movements, the 330105 facilitates predictive maintenance and prevents costly unplanned downtime.
The model code 330105-00-32-05-02-00 defines a specific mechanical footprint optimized for internal machine mounting.
The configuration specifies a standard reverse mount body. Unlike standard "forward" probes, the reverse mount design allows the probe to be secured within a 3/8-24 threaded housing or a Bently Nevada probe sleeve, facilitating easy gap adjustment from the exterior of the machine.
The 05 option provides a 0.5-meter (1.6 feet) cable length. This short-coupled pigtail is ideal for installations where the Proximitor® or extension cable junction is located immediately adjacent to the machine casing, reducing the risk of cable snagging and electrical interference.
This probe features the Miniature ClickLoc™ coaxial connector. This gold-plated, locking interface eliminates the reliability issues associated with standard threaded connectors. It resists loosening under the high-frequency vibration common in turbine decks.
The 00 designation indicates that no specific regional hazardous area approvals are selected. This makes it a cost-effective choice for general industrial applications or locations where "standard" electrical safety ratings are sufficient.

The 330105 series offers unique benefits for facility engineers and maintenance teams:
Internal Access Design: The reverse mount architecture allows for probe replacement and gapping in complex housings where a standard threaded probe cannot reach.
Superior Sealing: The PPS tip is chemically bonded to the stainless steel case, creating a leak-proof seal that prevents oil or process gas from migrating through the probe body into the cable conduit.
Thermal Stability: Bently Nevada’s 3300 XL technology minimizes "temperature drift," ensuring that vibration readings remain accurate even as the machine transitions from cold start to peak operating temperature.
Proper installation of a reverse-mount probe is critical for signal accuracy and hardware longevity.
Install the probe into the reverse-mount housing and monitor the DC voltage. For the 3300 XL system, a gap voltage of -10.0 VDC typically represents the center of the 80-mil linear range. Fine-tune the position until the voltage stabilizes before locking the jam nuts.
Always use a connector protector sleeve over the ClickLoc™ junction. This prevents environmental contaminants like moisture or oil from entering the coaxial connection, which can cause signal "spikes" or false vibration alarms.
Never use pliers or sharp tools on the cable. Maintain a minimum bend radius of 25.4 mm (1.0 inch). Sharp bends can damage the internal dielectric layer, leading to impedance changes that degrade the sensor's calibration.
Q1: What is the main difference between the 330101 and 330105 probes?
A1: The 330101 is a standard "forward" mount probe with external threads. The 330105 is a reverse mount probe, designed to be inserted into a separate housing or sleeve. They are electrically identical but mechanically distinct.
Q2: Can I use this probe with a standard 3300 XL 9-meter extension cable?
A2: Yes, provided your total system length (Probe + Extension Cable) matches the Proximitor® calibration (usually 5.0m or 9.0m). This 0.5m probe is typically used as part of a 5m or 9m total system.
Q3: Is the PPS tip resistant to chemicals?
A3: Yes, the PPS (Polyphenylene Sulfide) tip is highly resistant to most industrial chemicals, including ammonia, caustic solutions, and all common turbine lubricants.
Q4: How do I know if the ClickLoc™ connector is properly seated?
A4: The ClickLoc™ connector provides a distinct tactile "click" when fully engaged. Unlike threaded connectors, you do not need a torque wrench; the locking mechanism ensures a consistent electrical connection even in high-vibration environments.
