Bently Nevada 330780-90-00 11 mm Proximitor Sensor

Bently Nevada 330780-90-00 3300 XL 11 mm Proximitor Sensor

Product Introduction

The Bently Nevada 330780-90-00 brings the same advanced features as the 3300 XL 8 mm model but in a larger 11 mm format. Its thin design supports both high-density DIN-rail and traditional panel mount installations. Improved RFI/EMI immunity allows European CE mark approval without special mounting considerations. Additionally, this immunity prevents nearby high-frequency radio signals from affecting the transducer system. The SpringLoc terminal strips need no special installation tools. They enable faster and more robust field wiring connections.

Technical Specifications

Electrical Parameters

• Input: Accepts one non-contacting 3300 XL 11 mm Proximity Probe and Extension Cable.

• Power Requirement: -17.5 Vdc to -26 Vdc without barriers at 12 mA max consumption; -23 Vdc to -26 Vdc with barriers. Operation above -23.5 Vdc may reduce linear range.

• Sensitivity: Less than 2 mV change in output voltage per volt change in input voltage.

• Output Resistance: 50 Ω.

System Length

The Bently Nevada 330780-90-00 provides a 9.0 meter (29.5 feet) system length including extension cable. This matches the “90” option in the product number.

Calibration Details

The factory calibrates this Proximitor Sensor to AISI 4140 steel by default. Calibration to other target materials is available upon request.

Mechanical & Environmental Ratings

Proximitor Sensor Material

A380 aluminum ensures durability in industrial environments.

Temperature Range

• Operating: -52°C to +100°C (-62°F to +212°F)

• Storage: -52°C to +105°C (-62°F to +221°F)

Relative Humidity

The sensor withstands 100% condensing humidity. It remains non-submersible when connectors are protected. It has passed IEC 68-2-3 damp heat testing.

Dimensions (HxWxD)

Approximately 6.35 cm x 6.12 cm x 8.13 cm.

Installation & Mounting Guide

Mounting Options

The 3300 XL 11 mm Proximitor Sensor supports panel mount configuration, as indicated by the “90” option code. You can also install it on high-density DIN rails.

Wiring Convenience

SpringLoc terminal strips simplify field wiring. They require no special tools and create highly robust connections. First, strip the wire to the correct length. Next, insert the wire into the terminal. Finally, press down to lock it securely.

RFI/EMI Best Practices

Although this model has excellent immunity, avoid placing it directly next to high-power radio transmitters. This ensures optimal performance in all conditions.

Target Material Consideration

For non-AISI 4140 steel targets, request factory recalibration before ordering. This step guarantees accurate measurements.

Frequently Asked Questions (FAQ)

1. Can I use the Bently Nevada 330780-90-00 with non-AISI 4140 steel targets?

Yes, but factory recalibration is required. Please request this option when placing your order.

2. What happens if I operate the sensor above -23.5 Vdc?

Operating at a more positive voltage than -23.5 Vdc may reduce the linear measurement range. Always stay within -23 Vdc to -26 Vdc when using barriers.

3. Is this Proximitor Sensor suitable for outdoor installations?

It withstands 100% condensing humidity and -52°C temperatures. However, keep connectors protected from submersion. Outdoor use is fine with proper enclosures.

4. Does the 9.0 meter system length include the probe and cable?

Yes, the “90” option means 9.0 meters total system length including the extension cable. The probe and sensor together provide this full length.

5. How do I mount the 3300 XL 11 mm Proximitor Sensor on a DIN rail?

Its thin design fits standard high-density DIN rails. Simply clip the sensor onto the rail until it clicks. No additional tools are needed for this process.
