Bently Nevada 330878-51-05 3300 XL Proximitor Sensor

Bently Nevada 330878-51-05 3300 XL 50 mm Proximitor Sensor

Product Introduction

The Bently Nevada 330878-51-05 belongs to the trusted 3300 XL series. This 50 mm Proximitor Sensor measures vibration and position in rotating machinery. Its slim design supports high-density DIN-rail or traditional panel mounting.

Additionally, the sensor provides excellent RFI/EMI immunity. This feature allows European CE mark approval without extra shielding. Therefore, the 3300 XL Proximitor Sensor works well near high-frequency radio signals. It prevents signal interference and ensures stable readings.

Key Technical Specifications

The Bently Nevada 330878-51-05 accepts one noncontacting 3300 XL 50 mm probe and extension cable.
Power requirement ranges from -17.5 Vdc to -26 Vdc without barriers at 12 mA max consumption. With barriers, use -23 Vdc to -26 Vdc.

Operating at a voltage more positive than -23.5 Vdc may reduce the linear range.
Output resistance is 50 Ω.
Extension cable capacitance measures 69.9 pF/m (21.3 pF/ft) typical.

The factory calibrates this sensor to AISI 4140 steel. However, calibration to other target materials is available upon request.

Mechanical and Environmental Parameters

The 330878-51-05 uses A380 aluminum for the Proximitor Sensor housing.
Operating temperature range is -51°C to +100°C (-60°F to +212°F).
Storage temperature range is -51°C to +105°C (-60°F to +221°F).

These wide ranges make the sensor suitable for harsh industrial environments.

Mounting and Installation Features

This Proximitor Sensor includes a 5.0 metres (16.4 feet) system length with panel mount option.
The SpringLoc terminal strips require no special tools. Consequently, field wiring becomes faster and more robust.

Furthermore, the thin profile allows high-density mounting on DIN rails. Alternatively, you can install it in traditional panel configurations.
For best results, ensure the target material matches the calibration. Use the correct extension cable to maintain capacitance specifications.

Frequently Asked Questions (FAQ)

1. Can I use the 330878-51-05 with a different target material?
Yes. The factory can calibrate this 3300 XL Proximitor Sensor to other materials upon request. Contact your supplier for special calibration.

2. What happens if I supply -22 Vdc to this sensor?
Operating above -23.5 Vdc may reduce the linear range. Therefore, always stay within -23.5 Vdc to -26 Vdc when using barriers.

3. Does the 3300 XL Proximitor Sensor need special shielding for CE mark?
No. The Bently Nevada 330878-51-05 has high RFI/EMI immunity. Hence, it achieves CE approval without special mounting or shielding.

4. How do I mount the sensor in a crowded cabinet?
Thanks to its thin A380 aluminum housing, you can mount it on high-density DIN rails. SpringLoc strips simplify wiring in tight spaces.

5. What is the maximum cable length supported?
The system length is fixed at 5.0 metres for this model. Use the specified extension cable to maintain 69.9 pF/m capacitance for accurate readings.
