Core System Components

Probe Assembly and Physical Configuration

The Bently Nevada 330102-00-20-10-01-05 features a probe with an overall length of 200 millimeters from the tip to the connector. This probe uses standard 3/4-20 UNF threading for universal mounting compatibility. Its PPS tip encapsulates a precision coil that generates the eddy-current field. This robust construction resists mechanical stress and chemical exposure in demanding industrial settings.

Cable Interconnection and Signal Routing

A 10-meter extension cable connects the probe assembly to the proximitor signal processor. This cable uses a fluoropolymer jacket that provides exceptional resistance to abrasion and elevated temperatures. Gold-plated 6-pin connectors at each termination ensure reliable, corrosion-free electrical contacts. Accordingly, the Bently Nevada 330102-00-20-10-01-05 maintains signal quality even when you route cables through long conduit runs.

Proximitor Signal Processing Function

The proximitor drives the probe’s oscillator circuit and converts the resulting impedance changes into a DC output voltage. This output varies linearly from -1.5 VDC at maximum gap to -23.5 VDC at minimum gap. The system draws approximately 12 milliamperes from a -24 VDC power supply during normal operation. Its sensitivity holds steady at 7.87 millivolts per micrometer with a tolerance of ±5%.

Measurement Linearity and Accuracy

This transducer provides a 2.0-millimeter linear range that covers most radial vibration and thrust measurement applications. The system maintains linearity within 0.5% of full scale when you correctly set the initial probe gap. This high accuracy allows operators to detect subtle shaft movements indicative of developing bearing faults or rotor imbalance.

Installation and Application

Installing the Bently Nevada 330102-00-20-10-01-05 requires threading the probe into a suitable housing and connecting the cable to the proximitor. You then adjust the probe gap to position the output voltage at approximately -10 VDC. This transducer suits all common turbomachinery monitoring applications including radial vibration, axial thrust, and differential expansion measurement.
