Bently Nevada 330180-91-CN 3300 XL Proximitor Sensor
Bently Nevada 330180-91-CN Proximitor Sensor. Brand New Original Stock available for Global Shipping.
Description
The Bently Nevada 330180-91-CN, also cataloged as the 3300 XL Proximity Sensor, operates as a dedicated hardware component for static position and dynamic vibration processing within fluid-film bearing monitoring systems. It conditions signal inputs from an 8 mm proximity probe and extension cable assembly to provide an output voltage directly proportional to the gap distance between the probe tip and conductive target surface.

Vibration Processing & Rotor Dynamics Integration
The 330180-91-CN utilizes precise eddy-current probe scaling to evaluate high-speed rotor dynamics on industrial rotating machinery. Operational field setup requires gap voltage validation (-10 VDC target at mid-range) to establish accurate calibration across the sensor’s voltage output sweep. The internal circuit design minimizes channel interference and provides effective cross-talk suppression when adjacent proximity sensors monitor orthogonal shaft positions in crowded bearing housing assemblies.
Frequently Asked Questions
Q: What is the primary function of the 35 mm DIN rail mounting option designated by the -91 suffix?
A: The -91 suffix designates a integrated mounting base designed for direct installation onto standard 35 mm DIN rail networks without external hardware adapters.
Q: Can the 330180-91-CN system accommodate component swaps without recalibration?
A: Yes, all 3300 XL series components maintain modular interchangeability, allowing replacement of probes, extension cables, and Proximitor sensors of identical system lengths without manual bench calibration.
Q: Is a match between total cable-probe physical length and sensor design required?
A: Yes, the total physical length of the probe and extension cable combined must equal the 9.0 meters design specification of the 330180-91-CN sensor to ensure accurate scale factor performance.
Field Installation Guidelines
- Mount the 330180-91-CN securely onto a grounded 35 mm DIN rail inside an enclosure sealed against dirt, oil, and atmospheric moisture.
- Connect coaxial cable terminals firmly, applying silicone tape or insulated terminal boots over connections to avoid metallic contact with local ground planes.
- Verify gap voltage validation shows -10.0 VDC (±0.5 VDC) at static conditions before connecting output wiring to TSI monitoring systems or API 670 racks.
- Route target signal cabling through dedicated metallic conduit, keeping high-voltage power lines isolated to reduce electromagnetic interference.
