Product Introduction
The Bently Nevada 330930-045-01-00 is a non-contact eddy current proximity probe, part of the renowned 3300 XL series from Bently Nevada. This sensor is widely used for critical machine monitoring in industrial environments. It offers high-precision shaft vibration and displacement measurements in rotating machinery, such as turbines, compressors, pumps, and motors. The 330930-045-01-00 comes with a probe tip, armor cable, and a connector, delivering consistent and accurate readings even in harsh conditions.
Designed with a 5mm tip and a 45-inch armored cable, this model is optimized for applications that require long cable runs without signal degradation. It interfaces with Bently Nevada proximitor sensors to provide linear and reliable outputs, enabling predictive maintenance and machinery protection in real time.

Frequently Asked Questions (FAQs)
Q1: What is the main function of the 330930-045-01-00 proximity probe?
A1: It detects the relative motion and vibration of rotating shafts in machinery using non-contact eddy current technology.
Q2: Is this probe compatible with all Bently Nevada systems?
A2: It is specifically designed for use with the 3300 XL Proximitor Sensor system and may not be compatible with other series without modification.
Q3: Can this probe be used in hazardous or high-temperature environments?
A3: Yes, it is built to withstand temperatures up to +177°C and has a sealed design for oil and dust protection.
Q4: What does the “045” in the model number indicate?
A4: It signifies the probe cable length, which in this case is 45 inches.
Q5: How is the probe installed?
A5: It is mounted via a threaded tip (3/8-24 UNF) into a fixed bracket, positioned close to the rotating shaft.
Q6: Does the probe need calibration?
A6: No, it comes pre-calibrated from the factory, but system calibration with proximitor sensors is required during setup.
Q7: Is this probe reusable after removal?
A7: Yes, if undamaged. However, the armored cable should be inspected to ensure integrity before reinstallation.
Q8: Can it detect both vibration and shaft position?
A8: Yes, it provides data that can be used to measure both radial vibration and axial shaft position.
Q9: How does the armor help the probe?
A9: The armor protects the internal cable from mechanical damage, oil, and environmental exposure.
Q10: Is a longer cable length available?
A10: Yes, Bently Nevada offers other variants with different lengths such as 60, 80, or 100 inches.
