3300 5mm Probes and XL Extension Cables can be ordered with connector protectors already installed, or the connector protectors supplied separately for installation in the field (such as when the cable must be run through restrictive conduit). Connector protectors are recommended for all
installations and provide increased environmental protection7.
Notes:
1. A 5 mm probe uses smaller physical packaging while providing the
same linear range as a 3300 XL 8 mm probe (ref 141194-01);
however, it does not permit reduced sideview clearances or tip-to-tip spacing requirements compared to an XL 8 mm probe. It is used when physical (not electrical) constraints preclude the use of an 8 mm probe, such as mounting between thrust bearing pads or other constrained spaces. When narrow sideview probes are required, use the 3300 XL NSv™ probe and extension cable with the 3300 XL NSv Proximitor® Sensor (refer to Specifications and Ordering Information p/n 147385-01).
2. XL 8 mm probes provide a thicker encapsulation of the probe coil in
the molded PPS plastic probe tip. This results in a more rugged probe. The larger diameter of the probe body also provides a stronger, more robust case. Bently Nevada recommends the use of XL 8 mm probes when possible to provide optimal robustness against physical abuse. 3. A 3300 XL Proximitor® Sensor is available and provides many
improvements over the non-XL version. It is electrically and
mechanically interchangeable with the non-XL version. Although the packaging of the 3300 XL Proximitor® Sensor differs from its predecessor, its design allows it to fit in the same 4-hole mounting pattern when used with the 4-hole mounting base, and to fit within the same mounting space specifications (when minimum permissible cable bend radius is observed). Consult Specifications and Ordering
Information (p/n 141194-01) or our Bently Nevada Sales and Service Professional for more information.
4. Us of XL components with 3300 5mm Probes will limit system
performance to the specifications for the non-XL 3300 system.
5. The factory supplies Proximitor® Sensors calibrated by default to AISI
4140 steel. Calibration to other target materials is available upon request.
6. When considering this transducer system for tachometer or over speed
measurements, consult www.bently.com for the application note regarding the use of eddy current proximity probes for over speed protection.
7. Silicone tape is also provided with each 3300 XL extension cable and
can be used instead of connector protectors. Silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil.
Specifications
Unless otherwise noted, the following specifications are for a proximity transducer system between +18° C and +27° C (+64° F to +80° F) with a -24 Vdc power supply, a 10 kΩ load, an AISI 4140 steel target, and a probe gapped at 1.27 mm (50 mils).

When gapped at the center of the linear range, the interaction between two separate transducer systems (cross-talk) will be less than 50 mV on shaft diameters of at least 50 mm (2 in) or greater. Care should be taken to maintain minimum separation of transducer tips, generally at least 40 mm (1.6 in) for axial position measurements or 38 mm (1.5 in) for radial vibration measurements to limit cross-talk to 50 mV or less. Radial vibration or position measurements on shaft diameters smaller than 76.2 mm (3 in) will generally result in a change in scale factor.

Note: Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal.
Extension Cable Temperature Range:
-51° C to +177° C (-60° F to +351° F) for standard extension cable. ref 141194-01
Probe Pressure:
3300 5 mm probes are designed to seal differential pressure between the probe tip and case. The probe sealing material consists of a fluorocarbon O-ring. Probes are not pressure tested prior to shipment. Contact our custom design department if you require a test of the pressure seal for your application.
Note: It is the responsibility of the
customer or user to ensure that all liquids and gases are contained and safely controlled should leakage occur from a proximity probe. In addition, solutions with high or low pH values may erode the tip assembly of the probe causing media leakage into surrounding areas. Bently Nevada®, LLC will not be held responsible for any damages resulting from leaking 3300 5 mm proximity probes. In addition, 3300 5 mm proximity probes will not be replaced under the service plan due to probe leakage.
