Product Description
The Bently Nevada 330100-90-00 is a high-precision Proximitor Sensor and the core electronic component of the 3300 XL 8 mm Proximity Transducer System. It measures shaft vibration, axial position, and speed on critical rotating machinery by converting the change in gap between a proximity probe and the target into a standardized voltage output of 200 mV/mil.
The “-90” configuration is calibrated for a 9.0-meter total system length, enabling longer cable runs between machinery and monitoring cabinets, providing greater flexibility in large-scale plants. Like all 3300 XL components, this sensor offers Total Interchangeability, meaning it can be used with any 3300 XL 8 mm probe and extension cable, provided the total physical length matches the 9.0 m calibration.

Application Scenarios
The 330100-90-00 is essential for machinery protection and condition monitoring in:
-
Steam and Gas Turbines: Monitoring radial vibration to detect rotor unbalance or bearing issues.
-
Centrifugal Compressors: Tracking axial thrust to prevent catastrophic internal contact.
-
Hydroelectric Generators: Measuring eccentricity and shaft runout at low speeds.
-
Keyphasor® Applications: Providing once-per-turn timing pulses for vibration phase analysis.
Frequently Asked Questions
Q: Can I use a 5-meter extension cable with this 9-meter sensor?
A: No. Using a shorter cable with a sensor calibrated for 9 m will result in non-linear output and an incorrect scale factor. The sensor’s system length must match the combined probe + cable length.
Q: What are the advantages of the 3300 XL over older 3300 models?
A: The 3300 XL offers improved temperature stability, better signal-to-noise ratio, and features the ClickLoc connector system, which prevents connectors from loosening due to machinery vibration.
