Product Overview

The Bently Nevada 330780-51-05 is a 3300 XL 11 mm Proximitor Sensor. It shares the same advanced features found in the 3300 XL 8 mm Proximitor Sensor.

The thin design allows mounting in either a high-density DIN-rail installation or a traditional panel mount configuration. Improved RFI/EMI immunity enables European CE mark approvals without special mounting considerations. This RFI immunity also prevents the transducer system from being adversely affected by nearby high frequency radio signals. Consequently, the 330780-51-05 delivers reliable performance in electrically noisy environments.

AISI 4140 steel.

Optional Calibration:
Calibration to other target materials is available upon request. Contact your local Bently Nevada representative for details.

Key Features

The 330780-51-05 offers several advantages for proximity measurement applications.

Thin Profile Design:
The slim housing allows high-density DIN-rail mounting. Alternatively, traditional panel mount configuration is also supported. Therefore, installation is flexible in various cabinet layouts.

Advanced RFI/EMI Immunity:
European CE mark approvals are achieved without special mounting considerations. Nearby high frequency radio signals do not adversely affect the transducer system. Consequently, reliable operation is maintained in electrically noisy environments.

SpringLoc Terminal Strips:
These terminal strips require no special installation tools. They facilitate faster, highly robust field wiring connections. As a result, installation time and maintenance costs are reduced.

Wide Temperature Range:
Operating range spans -52°C to +100°C. Storage range extends to +105°C. Therefore, the 330780-51-05 suits extreme environment applications.

Multiple Agency Approvals:
The -05 option provides multiple approvals. Country specific approvals may also be available. Consult your local Customer Care Representative for more information.

System Components

The 330780-51-05 includes the Proximitor Sensor with integrated electronics. It accepts one 3300 XL 11 mm Proximity Probe and Extension Cable. The system length of 5.0 meters includes the probe and extension cable combined.

Typical Applications

The 330780-51-05 suits various proximity measurement applications.

• Radial vibration monitoring on large turbomachinery.

• Thrust position measurement on compressors and turbines.

• Shaft eccentricity monitoring during startup.

• Differential expansion measurements on steam turbines.

• Speed and phase reference detection.

Installation Guidelines

Install the 330780-51-05 on a DIN rail or panel mount as required. For high-density installations, use the DIN rail mounting option.

Wiring Connections:
Use the SpringLoc terminal strips for field wiring. No special tools are required. Ensure the power supply meets the voltage requirements. Without barriers, supply -17.5 Vdc to -26 Vdc. With barriers, supply -23 Vdc to -26 Vdc.

Probe Connection:
Connect the 3300 XL 11 mm Proximity Probe and Extension Cable to the Proximitor Sensor. The total system length is 5.0 meters.

Temperature Considerations:
Ensure the operating temperature stays between -52°C and +100°C. Protect connectors from submersion, though 100% condensing humidity is acceptable.
