Advanced Design Features

The 3300 XL probe incorporates several patented technologies that set it apart from previous designs. Specifically, the TipLoc molding method creates a more robust bond between the probe tip and body. This significantly reduces the risk of tip separation during operation. Additionally, the CableLoc design provides 330 N (75 lbf) pull strength. This securely attaches the probe cable to the tip assembly.

Furthermore, the 8 mm design offers thicker encapsulation of the probe coil in molded PPS plastic. This results in a more rugged and durable probe. The larger diameter also provides a stronger, more robust case. Therefore, Bently Nevada recommends using 8 mm probes whenever possible. They provide optimal robustness against physical abuse in demanding environments.

FluidLoc Cable Option

This model includes the FluidLoc cable option (Code 12). This feature prevents oil and other liquids from leaking out of the machine through the cable's interior. Consequently, it provides enhanced protection in applications with potential fluid exposure. The FluidLoc design adds an extra layer of security for critical monitoring systems.

Electrical Characteristics

The Bently Nevada 330101-33-53-10-12-05 provides stable electrical performance across its operating range. The extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. Field wiring recommendations include 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum field wiring length is 305 meters (1,000 feet) between the Proximitor Sensor and monitor.

The standard 1-meter system delivers an Incremental Scale Factor of 7.87 V/mm (200 mV/mil) ± 5%. This includes interchangeability error when measured over the 80-mil linear range from 0°C to +45°C. The Deviation from best fit straight line (DSL) is less than ±0.025 mm (±1 mil) for the 1-meter system.

Hazardous Area Approvals

This model carries comprehensive hazardous area certifications (Code 05). Specifically, it holds CSA, ATEX, and IECEx approvals. These certifications enable installation in various hazardous locations worldwide. Always verify the specific classification requirements for your application before installation.

Important Note About Temperature

Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Therefore, consider your operating environment carefully. Select the extended temperature range option if your application requires operation below this threshold.

Installation and Mounting Guide

Proper installation of the 3300 XL probe ensures optimal performance and longevity. First, verify the 3/8-24 UNF thread compatibility with your mounting hardware. Next, clean the target surface thoroughly to remove any contaminants. Furthermore, set the recommended gap to approximately -9 Vdc [1.27 mm (50 mils)] for radial vibration applications. Never exceed the specified linear range of 2 mm (80 mils). Finally, connect the Bently Nevada 330101 to the appropriate extension cable using the ClickLoc connector. For FluidLoc models, ensure the sealing mechanism engages properly.
