Frequently Asked Questions (FAQ)
-
What does the model number 330103-00-03-50-02-05 indicate?
It specifies the configuration of the probe, including cable lengths, connector options, and physical design per Bently Nevada’s part numbering system. -
Is this proximity probe compatible with other Bently Nevada systems?
Yes, it’s compatible with the 3300 XL Proximitor and related systems, especially the 3300 and 3500 monitoring series. -
Can this probe be used in hazardous environments?
With appropriate installation and certifications (ATEX, CSA), it can be deployed in hazardous locations. -
What is the typical lifespan of this proximity probe?
When installed properly, it can last for many years—up to 10+ years depending on environmental factors. -
Does it support condition monitoring or just protection?
It supports both. It provides real-time data for condition monitoring and integrates with machinery protection systems. -
How is the probe calibrated?
Calibration is typically performed using a static calibrator or within the monitoring system configuration, referencing known standards. -
Is the 330103-00-03-50-02-05 field-repairable?
No, probes are sealed units. If damaged, they must be replaced. -
What kind of shaft materials are compatible for accurate reading?
Standard targets are made from AISI 4140 steel or similar ferromagnetic materials. -
How is the extension cable terminated?
It uses coaxial connectors with a protective boot and keying to prevent misconnection. -
Can this probe system operate underwater?
