Product Description:

The Bently Nevada 330102-02-12-20-01-CN is an 8 mm armored proximity probe belonging to the industry-standard 3300 XL Series. It is engineered primarily for continuous condition monitoring and machinery protection in high-stakes, rotating industrial equipment. The "CN" suffix designates that it carries country-specific approvals for China, making it highly optimized for hazardous, classified environments in East Asian markets.The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.

Frequently Asked Questions (FAQ)

Q:Can this probe withstand fluid submersion?

A:The standard tip material is Polyphenylene Sulfide (PPS), which resists most industrial oils and chemicals. While the tip resists splash exposure, if you require a pressurized fluid barrier through the internal core of the cable itself, you should verify if your application requires an optional FluidLoc™ cable upgrade.
Q:How do I test if the probe loop is damaged?
A:You can perform a quick resistance check using a multimeter. Check for continuity between the center conductor and the outer shield of the ClickLoc™ connector; standard probe resistance typically falls between 4.0 Ω and 11.0 Ω depending on the cable length and temperature. Any short or open circuit means the probe must be replaced.

Q:What does the "with armor" designation mean?
A:The probe cable is completely encased in a flexible, stainless steel braided armor sleeve. This provides rugged mechanical protection against physical abrasion, sharp edges, and pinch points inside the machine housing.
