330780-90-CN Bently Nevada Proximity Sensor 9m

Bently Nevada 330780-90-CN 3300 XL Sensor

Product Introduction

The Bently Nevada 330780-90-CN belongs to the trusted 3300 XL series. This 11 mm Proximitor Sensor is built for non-contacting vibration and position measurement. It shares the same advanced features as the 8 mm version but offers a larger measurement range.

For instance, its thin housing allows easy mounting in tight spaces. You can install it on a high-density DIN-rail or use a traditional panel mount setup. This specific model comes with a 9.0 meter (29.5 feet) system length. The “CN” suffix indicates a country-specific agency approval option.

Additionally, the 3300 XL 11 mm Proximitor Sensor shows excellent immunity to RFI and EMI. This feature helps it achieve European CE mark approvals without any special mounting steps. Nearby high-frequency radio signals will not adversely affect this transducer system. The SpringLoc terminal strips are another practical feature. They require no special tools for installation. As a result, you get faster and highly robust field wiring connections.

Technical Specifications

This Proximitor Sensor ships calibrated to AISI 4140 steel by default. However, calibration for other target materials is available upon request.

Electrical Parameters:

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

• Power Requirement: Needs -17.5 Vdc to -26 Vdc without barriers (12 mA max). With barriers, it requires -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 & Mounting Parameters

The 330780-90-CN operates reliably under harsh conditions. Its operating temperature ranges from -52°C to +100°C (-62°F to +212°F). Storage temperature extends to -52°C to +105°C (-62°F to +221°F). Meanwhile, it tolerates 100% condensing humidity. The unit is non-submersible when connectors are properly protected. Bently Nevada tested it according to IEC 68-2-3 for damp heat.

Mounting Options:
This model is the “panel mount” version. Therefore, you can secure it directly onto a panel. Alternatively, its thin design also fits standard DIN-rail mounting systems.

Installation Guidelines

First, ensure the power supply is within the required range. Using a voltage more positive than -23.5 Vdc can reduce the linear range. Next, connect the 3300 XL 11 mm probe and extension cable to the Proximitor Sensor. Then, use the SpringLoc terminal strips for wiring. Simply insert the wire and close the lever. No special tools are needed. Finally, mount the sensor in a dry area. Remember to protect all connectors from direct water immersion.

Frequently Asked Questions (FAQ)

1. What is the difference between the 3300 XL 8 mm and the 11 mm sensor?
The 3300 XL 11 mm Proximitor Sensor provides a larger linear measurement range than the 8 mm version. Thus, it is better for applications with greater shaft vibration or runout.

2. Is the probe included with the 330780-90-CN?
No, the proximity probe and extension cable are not included. This listing is for the Proximitor Sensor only. You must purchase the 11 mm probe and cable separately.

3. Can I use this sensor with a target material other than AISI 4140 steel?
Yes. While the factory calibration is set for AISI 4140 steel, Bently Nevada offers custom calibration for other materials. Please request this service before ordering.

4. Does the “CN” approval affect performance?
No. The “CN” suffix stands for country-specific approval documentation. It does not change the electrical or mechanical performance of the 3300 XL 11 mm Proximitor Sensor.

5. How do I clean the SpringLoc terminals if they get dirty?
Use a small brush or compressed air to remove debris. Avoid using liquids inside the terminal area. The robust design of the 330780-90-CN ensures reliable contact even in dusty environments.
