Bently Nevada 330980-51-00 3300 XL NSv Proximitor Sensor

330980-51-00 NSv Proximitor Sensor

Product Introduction

The 330980-51-00 is a member of Bently Nevada's 3300 XL NSv series. It shares core technology with the standard 3300 XL 8 mm Proximitor Sensor. Its compact, thin design supports either high-density DIN-rail or traditional panel mounting. This sensor works with one 3300 RAM or 3300 NSv proximity probe and extension cable. You benefit from enhanced radio frequency interference immunity. Therefore the 330980-51-00 easily achieves CE mark approval without special mounting considerations.

Furthermore, SpringLoc terminal strips eliminate the need for special tools. You complete field wiring connections faster and more securely. The 330980-51-00 also rejects nearby high-frequency radio signals. Consequently your measurement data stays clean and reliable even near VFDs or radio equipment.

Technical Specifications

Electrical Parameters

• Input: Accepts one noncontacting 3300 RAM or 3300 NSv probe with extension cable.

• Power Requirement: Operates from -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption. With barriers, use -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

System Accuracy Conditions

Unless otherwise noted, specifications apply between 0°C and +45°C at 2000 m maximum altitude. You need a -24 Vdc power supply, 10 kΩ load, and a Bently Nevada AISI 4140 steel target (31 mm diameter or larger). Set the probe gap to 1.0 mm (40 mils). System accuracy does not apply when you use any other target material.

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

Humidity and Protection

• Relative Humidity: 100% condensing, non-submersible when connectors are protected. Tested to IEC 68-2-3 damp heat.

Installation Guide

DIN-Rail Mounting (Suffix 51)

The "51" suffix specifies 5.0 metre (16.4 feet) system length with DIN-rail mount. This configuration suits modern control cabinets with high-density layouts. You simply clip the sensor onto standard 35 mm DIN-rail. No additional mounting plate is required.

Alternative Mounting Options

Although the 330980-51-00 comes with DIN-rail hardware, the sensor body itself also supports panel mount. You can order separate brackets if you change your cabinet layout later. This flexibility protects your investment.

Wiring with SpringLoc Terminals

SpringLoc terminal strips make wiring straightforward. First, strip the wire to the correct length. Next, push it into the terminal until it locks. Finally, give a gentle tug to confirm security. No screwdriver is needed for termination.

Power Supply Best Practices

Operation at voltages more positive than -23.5 Vdc reduces linear range. Therefore always use a stable -24 Vdc supply. When intrinsic safety barriers are present, keep the supply between -23 Vdc and -26 Vdc.

Frequently Asked Questions (FAQ)

1. What is the difference between 330980-50-CN and 330980-51-00?
The 330980-50-CN uses panel mount with country-specific approval (CN). The 330980-51-00 uses DIN-rail mount with no agency approval (00). Both have the same 5.0 metre system length and electrical specifications.

2. Can I mount the 330980-51-00 on a panel instead of DIN-rail?
Yes, the sensor body supports both methods. However the "51" suffix ships with DIN-rail hardware only. You would need to purchase panel mount brackets separately.

3. What happens if my supply voltage drops below -17.5 Vdc?
The sensor may not operate correctly. Below -17.5 Vdc, you risk erratic output or complete shutdown. Always maintain the specified voltage range.

4. Is the 330980-51-00 CE certified?
Yes, the improved RFI/EMI immunity allows this sensor to achieve European CE mark approval. You do not need special mounting or additional shielding.

5. How long is the typical lead time for this model?
Stock levels vary. Contact us for current availability. Once shipped, delivery takes 3-7 business days via FedEx, UPS, or DHL.
