Bently Nevada 330980-50-CN NSv Proximitor Sensor

330980-50-CN NSv Proximitor Sensor

Product Introduction

The 330980-50-CN belongs to Bently Nevada’s 3300 XL NSv series. It shares many features with the standard 3300 XL 8 mm Proximitor Sensor. Its thin profile allows flexible mounting in high-density DIN-rail or traditional panel configurations. This sensor accepts one 3300 RAM or 3300 NSv proximity probe and extension cable. You get improved immunity against radio frequency interference. Thus the 330980-50-CN achieves CE mark approval without special mounting considerations.

Additionally, this model includes SpringLoc terminal strips for fast wiring. You need no special tools for installation. The 330980-50-CN also prevents nearby high-frequency radio signals from disturbing the transducer system. Therefore it suits harsh industrial environments near variable frequency drives or radio transmitters.

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 max. With barriers, use -23 Vdc to -26 Vdc.

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

• Output Resistance: 50 Ω

System Accuracy Conditions

Unless noted otherwise, specifications apply between 0°C and +45°C at 2000 m max altitude. You need a -24 Vdc supply, 10 kΩ load, and a Bently Nevada AISI 4140 steel target (31 mm diameter or larger). The probe gap must be 1.0 mm (40 mils). System accuracy does not apply when using other target materials.

Mechanical & Environmental Parameters

Material and Weight

• Proximitor Sensor Material: A380 aluminum

• Weight: 255 g (9 oz)

Temperature Ratings

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

• 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

Mounting Options

The 330980-50-CN supports two mounting styles. First, you can install it on a standard panel using the traditional method. Next, you can mount it on high-density DIN-rail systems. This flexibility saves space in control cabinets.

Wiring Connections

SpringLoc terminal strips simplify field wiring. You push the wire in, and it locks automatically. Consequently you finish installations faster. No torque tools or screwdrivers are needed for the terminals.

System Length and Cable

The "50" suffix indicates a 5.0 metre (16.4 feet) system length. The "CN" suffix denotes country-specific agency approval. Use only genuine Bently Nevada extension cables for full accuracy.

Power Supply Considerations

Operation above -23.5 Vdc reduces linear range. Therefore always provide a stable -24 Vdc supply for best performance. When using intrinsic safety barriers, keep the supply between -23 Vdc and -26 Vdc.

Frequently Asked Questions (FAQ)

1. Can I use the 330980-50-CN with a non-Bently Nevada target?
Yes, but system accuracy and interchangeability will not apply. For best results, always use a Bently Nevada AISI 4140 steel target.

2. What happens if I supply -20 Vdc instead of -24 Vdc?
The linear range reduces when voltage is more positive than -23.5 Vdc. Additionally, output sensitivity may increase. Always stay within -23 Vdc to -26 Vdc for full performance.

3. Is this sensor waterproof for outdoor use?
It withstands 100% condensing humidity. However it is not submersible. Protect all connectors from direct water immersion.

4. How do I clean the Proximitor Sensor housing?
Use a dry or slightly damp cloth with mild detergent. Do not immerse the unit. Also avoid abrasive cleaners on the A380 aluminum housing.

5. Does the CN approval affect delivery to my country?
The "CN" suffix means country-specific approvals for China. It does not restrict shipping. We ship worldwide via FedEx, UPS, or DHL.
