Bently Nevada 330780-91-CN 11mm Proximitor Sensor

Bently Nevada 330780-91-CN 3300 XL Sensor

Product Introduction

The Bently Nevada 330780-91-CN belongs to the renowned 3300 XL series. This 11 mm Proximitor Sensor specializes in non-contacting vibration and position monitoring. It offers the same advanced features as the 8 mm version but delivers a larger linear measurement range.

For instance, its thin housing fits perfectly into dense control cabinets. You can mount this device directly onto a standard DIN rail without extra hardware. This specific model provides a 9.0 meter (29.5 feet) total system length. The "91" option specifies DIN rail mounting, while the "CN" suffix indicates country-specific agency approval.

Additionally, the 3300 XL 11 mm Proximitor Sensor exhibits excellent RFI and EMI immunity. This characteristic enables European CE mark certification without special mounting considerations. Nearby high-frequency radio signals will not interfere with this transducer system. The SpringLoc terminal strips represent another practical advantage. They require no specialized installation tools. As a result, you achieve faster and more reliable field wiring connections.

Technical Specifications

This Proximitor Sensor ships from the factory calibrated to AISI 4140 steel. However, you can request calibration for other target materials when placing your order.

Electrical Parameters:

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

• Power Requirement: Requires -17.5 Vdc to -26 Vdc without barriers (12 mA maximum consumption). With barriers, it needs -23 Vdc to -26 Vdc.

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

• Output Resistance: 50 Ω.

Physical & Material:

• Proximitor Sensor Material: A380 aluminum.

• Dimensions (HxWxD): Approx. 6.35 cm x 6.12 cm x 8.13 cm.

• System Length: 9.0 meters (including extension cable).

Environmental & Operating Parameters

The 330780-91-CN operates reliably under extreme conditions. Its operating temperature ranges from -52°C to +100°C (-62°F to +212°F). Storage temperature extends from -52°C to +105°C (-62°F to +221°F). Meanwhile, it tolerates 100% condensing humidity. The unit remains non-submersible only when you properly protect all connectors. Bently Nevada tested this sensor according to IEC 68-2-3 for damp heat endurance.

Mounting Configuration:
This model features the DIN rail mount option. Therefore, you can snap it directly onto a standard 35 mm DIN rail. This configuration saves valuable panel space and simplifies overall installation.

Installation Guidelines

First, confirm your power supply stays within the required voltage range. Operating at a voltage more positive than -23.5 Vdc may reduce the linear measurement range. Next, connect your 3300 XL 11 mm probe and extension cable to the Proximitor Sensor. Then, use the SpringLoc terminal strips for all wiring connections. Simply insert each wire and close the lever firmly. No special crimping tools are needed for this process. Finally, clip the sensor onto your DIN rail. Ensure all connectors remain dry and protected from direct water exposure.

Frequently Asked Questions (FAQ)

1. What does the "91" mounting option mean for the 330780-91-CN?
The "91" option specifically indicates DIN rail mount. You can snap this 3300 XL 11 mm Proximitor Sensor directly onto a standard 35 mm DIN rail without any additional mounting brackets.

2. Is the probe included with this Proximitor Sensor?
No. This listing includes only the 330780-91-CN Proximitor Sensor itself. You must purchase the 3300 XL 11 mm proximity probe and extension cable separately.

3. What does the "CN" agency approval signify?
The "CN" suffix indicates country-specific agency approval. This version meets particular regulatory requirements for certain regions while maintaining the same electrical performance.

4. Can I use this sensor with a different target material?
Yes. While factory calibration uses AISI 4140 steel, Bently Nevada offers custom calibration for other materials. Please contact us to arrange this service before ordering.

5. How do I maintain the SpringLoc terminals on the 330780-91-CN?
Use clean, dry compressed air or a soft brush to remove debris. Avoid inserting liquids or sharp metal objects into the terminal area. The robust design of this Proximitor Sensor ensures reliable operation even in dusty industrial environments.
