Bently Nevada 330980-50-CN – NSv Proximitor Sensor for 3300 XL Systems

The Bently Nevada 330980-50-CN is an NSv Proximitor Sensor. Specifically, this sensor belongs to the 3300 XL product family. It shares similar features with the 3300 XL 8 mm Proximitor Sensor. Furthermore, its thin design allows flexible mounting options. Consequently, users can install it in high-density DIN-rail configurations. Alternatively, it fits traditional panel mount setups as well.

Ordering Options and Configuration

The 50 total length and mounting option provides 5.0 metres (16.4 feet) system length. Additionally, this option specifies panel mount configuration. Meanwhile, the CN agency approval option indicates country specific approval. For reference, the Bently Nevada 330980-50-CN is designed for versatility. The Proximitor Sensor Material is A380 aluminum. The sensor weight is 255 grams (9 ounces).

RFI and EMI Immunity Features

Improved RFI and EMI immunity enables European CE mark approvals. Specifically, no special mounting considerations are required for compliance. Furthermore, this RFI immunity prevents nearby high frequency radio signals from affecting the transducer system. Therefore, the Bently Nevada 330980-50-CN performs reliably in electrically noisy environments.

SpringLoc Terminal Strips

SpringLoc terminal strips require no special installation tools. Consequently, they facilitate faster field wiring connections. Additionally, these strips provide highly robust connections. They eliminate screw-type clamping mechanisms that can loosen over time. Thus, installation is both quick and dependable.

Input and Probe Compatibility

• Proximitor Sensor Input: Accepts one non-contacting probe.

• Compatible Probe 1: 3300 RAM Proximity Probe.

• Compatible Probe 2: 3300 NSv Proximity Probe.

• Extension Cable: Works with matching extension cable.

• Compatibility Note: Use with Bently Nevada probes only.

• Therefore, the Bently Nevada 330980-50-CN integrates seamlessly with existing 3300 systems.

Electrical Specifications

• Power Requirement (without barriers): -17.5 Vdc to -26 Vdc range.

• Maximum Consumption: 12 mA typical operation.

• Power Requirement (with barriers): -23 Vdc to -26 Vdc range.

• Voltage Warning: Operation above -23.5 Vdc reduces linear range.

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

• Output Resistance: 50 Ω nominal rating.

• Consequently, stable power delivery ensures accurate measurements.

Standard Test Conditions

Unless otherwise noted, specifications follow these conditions:

• Temperature Range: 0°C to +45°C (+32°F to +113°F).

• Maximum Altitude: 2000 metres.

• Power Supply: -24 Vdc nominal.

• Load: 10 kΩ.

• Target: AISI 4140 steel, 31 mm (1.2 in) diameter or larger.

• Probe Gap: 1.0 mm (40 mils).

• Important Note: System accuracy specifications do not apply with other target materials.

• Thus, calibration to Bently Nevada AISI 4140 steel is required for guaranteed performance.

Temperature and Environmental Ratings

• Operating Temperature: -52°C to +100°C range.

• Operating Temperature (F): -62°F to +212°F range.

• Storage Temperature: -52°C to +105°C range.

• Storage Temperature (F): -62°F to +221°F range.

• Relative Humidity: 100% condensing allowed.

• Submersion Note: Non-submersible when connectors are protected.

• Test Standard: Tested to IEC 68-2-3 damp heat.

• Moreover, the Bently Nevada 330980-50-CN withstands extreme environmental conditions.

Installation Guide

First, select either DIN-rail or panel mount for your installation. For panel mount, use the 50 option configuration. Then, mount the Bently Nevada 330980-50-CN securely in place. After that, connect the 3300 RAM or NSv probe to the sensor input. Attach the extension cable between probe and sensor. Next, strip field wires to the appropriate length. Then, insert wires into SpringLoc terminal strips. No special tools are required for this step. Afterward, apply -17.5 Vdc to -26 Vdc power to the sensor. However, verify the voltage stays below -23.5 Vdc for full linear range. For reference, standard test conditions use -24 Vdc with a 10 kΩ load. Finally, set the probe gap to the recommended 1.0 mm (40 mils) for AISI 4140 steel targets. As a result, the NSv Proximitor Sensor will provide accurate proximity measurements.
