Bently Nevada 330980-70-00 NSv Proximitor Sensor Overview

The Bently Nevada 330980-70-00 is a 3300 XL NSv Proximitor sensor made in the USA. It shares many features with the 3300 XL 8 mm Proximitor Sensor. However, its thin design offers unique mounting advantages. Specifically, the 330980-70-00 accepts one non-contacting 3300 RAM or 3300 NSv proximity probe. In addition, it works with extension cables for flexible system configurations. Total length and mounting option 70 provides 7.0 meters (23.0 feet) system length with panel mount configuration. Agency approval option 00 means no specific certifications are required. Therefore, this version suits non-hazardous installations only. The sensor mounts in high-density DIN-rail installations or traditional panel mount configurations.

Technical Specifications

The Bently Nevada 330980-70-00 has a total system length of 7.0 meters (23.0 feet) . This length includes the probe, extension cable, and Proximitor sensor combined. The mounting option specifies panel mount configuration for secure installation. The Proximitor sensor material is A380 aluminum for lightweight durability. Total sensor weight is 255 g (9 oz) for easy handling.

Now consider the power requirements for this sensor. Specifically, the 330980-70-00 requires -17.5 Vdc to -26 Vdc without barriers. Maximum current consumption is 12 mA. When using barriers, the range becomes -23 Vdc to -26 Vdc. However, operation above -23.5 Vdc can reduce the linear range significantly. Supply sensitivity shows less than 2 mV change in output voltage per volt change. Output resistance is 50 Ω for standard signal transmission.

Environmental & Temperature Range

The Bently Nevada 330980-70-00 operates across extreme temperature conditions. Operating temperature spans -52°C to +100°C (-62°F to +212°F) . Storage temperature ranges from -52°C to +105°C (-62°F to +221°F) . Relative humidity tolerance reaches 100% condensing conditions. However, the sensor is non-submersible when connectors are protected. It has been tested to IEC 68-2-3 damp heat standards. Consequently, this sensor suits outdoor and harsh industrial environments.

RFI/EMI Immunity & CE Mark Approval

The Bently Nevada 330980-70-00 demonstrates excellent RFI and EMI immunity. Improved immunity allows European CE mark approvals without special mounting considerations. Therefore, nearby high frequency radio signals cannot adversely affect this transducer system. As a result, you can install the 330980-70-00 in various enclosures without worry. Moreover, no special shielded conduit or metallic housings are required. Consequently, this reduces both installation costs and complexity for your projects.

The 330980-70-00 includes SpringLoc terminal strips for easy wiring. These terminals require no special installation tools. Specifically, the SpringLoc design eliminates screw-type clamping mechanisms completely. Traditional screw clamps can loosen under vibration over time. Therefore, SpringLoc provides faster and more reliable field wiring connections.

Calibration & Target Specifications

Unless otherwise noted, standard specifications apply under specific conditions. First, these conditions include temperatures between 0°C and +45°C at a maximum altitude of 2000 m. Second, a -24 Vdc power supply and 10 kΩ load are assumed. Third, the target must be Bently Nevada supplied AISI 4140 steel with 31 mm diameter or larger. Finally, probe gap is set to 1.0 mm (40 mils) for calibration.

However, note an important limitation about accuracy. System accuracy and interchangeability specifications do not apply when using other targets. Specifically, the 330980-70-00 must be calibrated to a Bently Nevada AISI 4140 steel target. Using different target materials will affect measurement linearity.

Key Features & Benefits

• Thin profile design – The 330980-70-00 fits high-density DIN-rail or panel mount installations.

• Wide temperature range – Operates reliably from -52°C to +100°C.

• High RFI immunity – CE mark approved without special mounting considerations.

• SpringLoc terminals – No special tools needed for fast, secure wiring.

• A380 aluminum housing – Lightweight at only 255 grams total weight.

• Flexible mounting – Panel mount configuration with 7.0 meter system length.

Installation Guidelines

Follow these steps to install the Bently Nevada 330980-70-00 correctly. First, mount the NSv Proximitor sensor on a panel using the 4-hole footprint. Second, connect the 3300 RAM or 3300 NSv probe to the sensor input. Next, attach the extension cable between the probe and the 330980-70-00 if needed. Then, wire the power supply using SpringLoc terminals with -17.5 Vdc to -26 Vdc. After that, connect the output signal wires to your monitoring system. Finally, verify the total system length does not exceed 7.0 meters.

However, do not operate the 330980-70-00 above -23.5 Vdc when using barriers. Otherwise, this reduces the linear measurement range significantly. Also, keep the probe tip at the calibrated 1.0 mm gap for best accuracy. Above all, use only Bently Nevada approved probes and cables with this sensor.

Frequently Asked Questions (FAQ)

1. What is the difference between NSv and standard Proximitor sensors?
The Bently Nevada 330980-70-00 has a thinner profile than standard 8 mm versions. As a result, this allows higher density mounting in panel or DIN-rail installations.

2. Does the 330980-70-00 work with 8 mm probes?
No. Specifically, the 330980-70-00 accepts only 3300 RAM or 3300 NSv proximity probes. Therefore, standard 8 mm probes are not compatible with this NSv model.

3. What approvals does this sensor have?
The Bently Nevada 330980-70-00 with suffix 00 has no agency approvals. Consequently, it is suitable for non-hazardous locations only. For hazardous areas, choose a version with 05 approval option.

4. Can I use this sensor with a non-steel target?
Yes, but accuracy will be affected. Specifically, the 330980-70-00 is calibrated for AISI 4140 steel targets. Different materials change the output linearity and sensitivity.

5. Is the 330980-70-00 CE marked?
Yes. In fact, the Bently Nevada 330980-70-00 achieves CE mark approval. Its improved RFI/EMI immunity meets European requirements without special mounting.
