Product Overview

The Bently Nevada 330780-90-05 is a 3300 XL 11 mm Proximitor Sensor. This model shares the same advanced features found in the 3300 XL 8 mm Proximitor Sensor.

Its 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. Furthermore, SpringLoc terminal strips require no special installation tools and facilitate faster, highly robust field wiring connections.

Key Features

The 330780-90-05 offers several advantages for proximity measurement.

Thin Profile Design:
Enables mounting in high-density DIN-rail installations. Alternatively, it suits traditional panel mount configurations. Consequently, installation flexibility is maximized.

Enhanced RFI/EMI Immunity:
Achieves European CE mark approvals without special mounting considerations. This immunity prevents adverse effects from nearby high frequency radio signals. Therefore, reliable operation near radios or wireless devices is assured.

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

Wide Temperature Range:
Operates from -52°C to +100°C. Storage temperature extends to +105°C. Hence, the sensor suits extreme climate conditions.

Multiple Agency Approvals:
The -05 suffix indicates multiple approvals. This simplifies global equipment certification.

Typical Applications

The 330780-90-05 suits various turbomachinery monitoring applications.

• Radial vibration monitoring on steam turbines.

• Axial position measurement on gas compressors.

• Shaft eccentricity monitoring on hydro turbines.

• Differential expansion measurement on large rotating equipment.

• Thrust position monitoring on industrial fans and blowers.

Installation Guidelines

Install the 330780-90-05 according to standard 3300 XL proximity system practices. Mount the Proximitor Sensor on a DIN rail or panel. Use the thin profile design for high-density mounting.

Connect the 3300 XL 11 mm Proximity Probe and Extension Cable to the sensor input. The system length is 9 meters including the extension cable.

Connect power at -17.5 Vdc to -26 Vdc. For installations with intrinsic safety barriers, use -23 Vdc to -26 Vdc. Ensure the voltage does not exceed -23.5 Vdc positive side to avoid reduced linear range.

The SpringLoc terminal strips accept simple wire insertion. No special tools are required. Protect connectors from submersible conditions. The sensor is not submersible but operates in 100% condensing humidity when connectors are protected.
