Bently Nevada 330180-90-CN 3300 XL Proximitor Sensor
Bently Nevada 330180-90-CN Proximitor Sensor. Brand New Original Stock available for Global Shipping.
Description
Configured for non-contact shaft vibration and axial position measurement in machinery protection systems, the Bently Nevada 330180-90-CN (3300 XL Proximitor Sensor) provides direct physical/electrical execution. It conditions signal input from a 3300 XL proximity probe and extension cable system into a linear voltage output proportional to the gap distance between the probe tip and the observed conductive target surface.

Machinery Monitoring & Signal Calibration
The 3300 XL Proximitor Sensor utilizes eddy-current probe scaling to convert mechanical displacement into an electrical signal. For proper rotor dynamics evaluation, field setup requires gap voltage validation (-10 VDC targets) at the midpoint of the sensor’s linear range during static conditions. Proper coaxial cable installation and dedicated isolation prevent cross-talk suppression issues when multiple proximity systems are mounted in close physical proximity within a single bearing housing.
Frequently Asked Questions
Q: What power supply voltage is required for the 330180-90-CN Proximitor Sensor?
A: The sensor operates on a nominal supply voltage of -24 VDC supplied from an external monitor or power supply unit.
Q: Can a 9.0 meter Proximitor Sensor be mismatched with a 5.0 meter cable and probe combination?
A: No, total system length must match the Proximitor Sensor design length of 9.0 meters (including probe and extension cable) to maintain proper calibration and accurate scale factor execution.
Field Installation Guidelines
- Mount the Proximitor Sensor on a grounded DIN-rail or panel plate inside a protective enclosure to maintain signal integrity and shield against environmental contamination.
- Maintain minimum physical clearance around the eddy-current probe tip to prevent metal side-viewing interference that alters linear scaling.
- Verify field target bias voltage reads -10.0 VDC (±0.5 VDC) using a digital multimeter at physical installation midpoint before final loop wiring to the 3500 monitoring rack.
- Ensure coaxial connectors between probe, extension cable, and Proximitor are clean, dry, and insulated using silicone tape or terminal boots to prevent field ground loops.
