Description

330780-90-05 | Bently Nevada | 3300 XL 11 mm Proximitor Sensor

### Product Description
The 330780-90-05 is a high-stability, shielded eddy-current proximity sensor in the Bently Nevada 3300 XL series. It delivers precise non-contact displacement and vibration measurements for rotating machinery.
Moreover, it interfaces directly with 3300 series monitors to support continuous condition monitoring of shaft position, vibration, and axial thrust. Therefore, it is routinely deployed in critical turbomachinery protection systems across power generation and oil & gas facilities. In addition, its 11 mm diameter probe offers optimized sensitivity and linear range for standard journal bearing applications.

### Technical Specifications

### Typical Applications
– Steam and gas turbine shaft vibration and axial position monitoring
– Centrifugal compressor shaft displacement and thrust bearing wear detection
– Hydroelectric generator rotor runout and air gap measurement
– Critical pump and fan shaft orbit analysis in refinery and chemical plant services

### FAQ
What is the linear range of the 330780-90-05?
