330180-12-05 | Bently Nevada | Proximitor Sensor

### Product Description
The 330180-12-05 is a high-precision eddy-current proximity sensor designed for continuous displacement and vibration monitoring. It delivers analog output proportional to target gap changes in rotating machinery.
Moreover, it serves as a primary sensing element in asset protection systems for detecting shaft position, vibration, and axial thrust in critical turbomachinery. Therefore, it is routinely integrated into Bently Nevada 3500/4000-series monitor racks for real-time condition monitoring. In addition, its robust construction ensures reliable operation in high-temperature, high-vibration industrial environments.

### Technical Specifications

### Typical Applications
– Steam and gas turbine shaft vibration and axial position monitoring
– Centrifugal compressor bearing housing vibration measurement
– Large electric motor rotor eccentricity and thrust monitoring
– Hydroelectric generator shaft runout and dynamic clearance verification

### FAQ
What is the standard output signal?
It provides a -2 to -18 VDC negative DC voltage output, linear with target gap.

Is calibration required before installation?
Yes—each sensor must be calibrated with its matching extension cable and proximitor module per API 670.

Can it operate in hazardous areas?
No—this model is non-incendive; use only in general-purpose or non-classified locations.

What is the maximum operating temperature?
The probe tip withstands up to +121 °C (250 °F); system performance depends on cable and module ratings.

Does it require a specific power supply?
Yes—it requires a regulated -24 VDC excitation supply from a compatible Bently Nevada monitor.
