The system provides an output voltage that is directlyproportional to the distance between the probe tip and theobserved conductive surface and can measure both static(position) and dynamic (vibration) values. The system'sprimary applications are vibration and positionmeasurements on fluid-film bearing machines, as well asKeyphasor reference and speed measurements3.

Frequently asked questions：

1. What type of probe is the 330101-00-55-05-11-00?

The 330101-00-55-05-11-00 is a 3300 XL 8 mm proximity probe designed for non-contact measurement of shaft vibration and displacement in rotating machinery.

2. What thread type does this probe use?

This probe is equipped with a 3/8-24 UNF mounting thread, which allows secure installation in standard probe holders and mounting brackets.

3. Does this 330101-00-55-05-11-00 probe include an unthreaded section?

No. The unthreaded length option is 0.0 inches, meaning the probe body is fully threaded up to the case.

4. What is the 330101-00-55-05-11-00 overall case length of the probe?

The probe has an overall case length of 5.5 inches, which provides sufficient mounting depth for industrial machinery monitoring applications.

Material and Environmental Limits

Datasheets from Nex Instrument Inc and Instrumart provide the following physical and environmental specifications for the 3300 XL 8mm series: 

Probe Tip Material: Polyphenylene sulfide (PPS).

Probe Case Material: AISI 303 or 304 stainless steel.

Operating Temperature: Standard range is -51 °C to +177 °C (-60 °F to +351 °F).

Pressure Seal: Designed to seal differential pressure between the tip and case; exposing the probe to temperatures below -34 °C (-30 °F) may cause seal failure

Performance Characteristics

As stated by Bently Nevada in the 3300 XL 8mm Proximity Transducer System datasheet:

Output Signal: Provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface.

Scale Factor: Typically 7.87 V/mm (200 mV/mil) for standard systems.

Linear Range: 2.0 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the probe tip.
