Bently Nevada 330195-02-12-50-CN Extended Temperature Range Reverse Mount Probe – 3300 XL 8mm Series
When a critical rotating machine loses its shaft vibration monitoring capability, the consequences are immediate and severe: undetected rotor imbalance, bearing wear, or shaft misalignment can escalate within minutes into catastrophic mechanical failure, unplanned downtime, and six-figure repair costs. In high-stakes environments — gas turbines, steam turbines, compressors, and pumps — continuous, accurate proximity measurement is not optional. It is the last line of defense between normal operation and disaster.
The Bently Nevada 330195-02-12-50-CN is a precision eddy current proximity probe engineered for the most demanding industrial environments. As part of the globally trusted 3300 XL 8mm Series, this Extended Temperature Range (ETR) Reverse Mount variant is specifically designed for installations where standard probes cannot survive — delivering reliable shaft displacement and vibration data even under extreme thermal stress. With millions of Bently Nevada probes deployed across power generation, oil & gas, and petrochemical facilities worldwide, the 3300 XL platform remains the industry benchmark for machinery protection systems.

Frequently Asked Questions
- Q: What does the “ETR” designation mean on the 330195-02-12-50-CN?
- A: ETR stands for Extended Temperature Range. This variant of the 3300 XL 8mm probe is engineered to maintain accurate performance at higher ambient and process temperatures than the standard probe, making it suitable for hot-section turbine and compressor applications.
- Q: What is the difference between a reverse mount and a standard mount probe?
- A: In a reverse mount configuration, the probe tip faces in the opposite direction relative to the connector end compared to a standard mount. This allows installation in machine housings where the probe must be inserted from the non-drive end or where physical space constraints prevent standard orientation.
- Q: Is the 330195-02-12-50-CN compatible with the Bently Nevada 3500 monitoring system?
- A: Yes. The 3300 XL probe system (probe + Proximitor® sensor) outputs a standard -24 VDC signal that is fully compatible with the Bently Nevada 3500 Series Machinery Protection System monitors.
- Q: Can Konmask.com supply the complete 3300 XL transducer system (probe + extension cable + Proximitor)?
- A: Yes. We can source and supply complete system sets or individual components. Please specify your requirements when submitting your inquiry.
- Q: What is the lead time for the 330195-02-12-50-CN?
- A: Lead time depends on current stock availability. Please contact us for a real-time availability check. We maintain relationships with multiple supply channels to minimize lead times for critical parts.
