Design Features and Construction
Probe Tip and Coil Technology
The Bently Nevada 330102-00-60-10-01-05 features a PPS probe tip that encapsulates a precision-wound induction coil. This advanced polymer offers outstanding resistance to chemical attack and thermal degradation. The coil maintains a stable inductance value of 3.2 microhenries across its entire specified temperature range. This stability ensures consistent oscillator drive characteristics for accurate gap measurements in critical machinery.
Mechanical Dimensions and Extended Length
This probe measures 600 millimeters from the sensing face to the connector termination. The extended overall length allows installation in deep bore applications where standard probes cannot reach the measurement surface. It includes a 10-millimeter threaded section with standard 3/4-20 UNF threads. The 316L stainless steel case provides exceptional corrosion protection and mechanical durability for long-term service.
Integral Cable and Connector Assembly
A 10-meter integral fluoropolymer-jacketed cable extends directly from the probe body for system interconnection. This cable length provides generous routing flexibility from deep measurement points to junction boxes. Gold-plated 6-pin connectors at the termination end create secure, low-resistance electrical contacts. The cable’s 25-millimeter minimum bend radius prevents internal damage during installation and maintenance activities.
Environmental Performance and Durability
This probe operates reliably across an exceptionally wide temperature range from -51°C to +177°C. It also withstands short-term storage temperatures up to +185°C without degrading its electrical characteristics. The sealed PPS tip design prevents moisture ingress that could compromise coil performance. These environmental tolerances make the Bently Nevada 330102-00-60-10-01-05 suitable for both steam turbine and gas compressor monitoring applications.
Installation and System Integration
Installing this probe requires threading it into a suitable mounting fixture or bearing housing assembly. You must set the probe gap correctly to achieve the proper DC bias voltage for the connected proximitor. The extended 600-millimeter length allows installation in applications where the mounting point sits far from the target surface. This probe integrates seamlessly with 3300 XL proximitors and 3500 rack monitoring systems for comprehensive protection solutions.
