Bently Nevada 330907-05-30-10-02-00 NSv Reverse Mount Probe

Bently Nevada 330907-05-30-10-02-00 3300 NSv Reverse Mount Probe

Product Introduction

The 330907-05-30-10-02-00 belongs to the trusted 3300 NSv Reverse Mount Probe series. Bently Nevada designed this model for tough industrial environments. It works especially well in process compressor applications. Its side-view characteristics are better than older 3000-series 190 probes. You can gap it at the same distance from the target with superior results. Additionally, this probe resists chemicals more effectively than the 3300 RAM probe.

Technical Specifications

The 330907-05-30-10-02-00 uses M10X1 threads. Its total length option is 1.0 meter (39 inches). The connector option is a miniature coaxial ClickLoc connector with standard cable. Agency approval is not required (00 option).

Probe DC Resistance

• For 1.0m length: 4.2 ± 0.5 ohms from center conductor to outer conductor.

Field Wiring

• Use 0.2 to 1.5 mm² (16 to 24 AWG) wire.

• For ferrules, use 0.25 to 0.75 mm² (18 to 23 AWG).

• Bently Nevada recommends three-conductor shielded triad cable.

• Maximum length between the Proximitor Sensor and monitor: 305 meters (1,000 feet).

Linear Range

• 1.5 mm (60 mils) total range.

• Linear range begins at approximately 0.25 mm (10 mils) from target.

• Operating range: 0.25 to 1.75 mm (10 to 70 mils) = about -1 to -13 Vdc.

• Recommended gap setting: 1.0 mm (40 mils).

• Recommended: 7.5 N•m (66 in•lb)

Weight

• Probe: Approximately 14 to 150 g (0.5 to 5.3 oz)

Thread Engagement Length

• For M10x1: 15 mm maximum

Temperature Range

• Operating: -52°C to +177°C (-62°F to +351°F)

• Storage: Same range

• Important: Exposure below -34°C (-30°F) for long periods may cause premature pressure seal failure.

Pressure Capability

• Sealing material: Viton O-ring.

Installation Guidelines

First, ensure the target surface is clean and smooth. Next, thread the 330907-05-30-10-02-00 carefully into the mounting hole. Use the recommended torque of 7.5 N•m. Do not exceed 22.6 N•m. Then, connect the ClickLoc connector. You will hear it lock into place. This prevents loosening from vibration.

Meanwhile, verify the gap setting at 1.0 mm (40 mils). Use a suitable gap tool or voltage measurement. For field wiring, keep total length under 305 meters. Use shielded triad cable for best signal quality.

Frequently Asked Questions (FAQ)

1. Can I use the 330907-05-30-10-02-00 in a wet gas compressor?
Yes. Its enhanced chemical resistance makes it suitable for many process compressor applications, including wet gas.

2. What happens if I exceed the maximum torque?
Exceeding 22.6 N•m may damage the probe case or threads. Always follow the recommended torque of 7.5 N•m.

3. Does this probe work with existing 3300 proximity systems?
Yes. The 3300 NSv Reverse Mount Probe is fully compatible with standard 3300 Proximitor sensors and monitors.

4. How do I prevent connection loosening?
The ClickLoc connector locks automatically. Additionally, you can use cable ties to secure the cable and reduce strain.

5. Is the 1.0m probe length measured including the connector?
No. The total length option refers to the probe body and cable, excluding the connector. For 330907-05-30-10-02-00, it is exactly 1.0 meter.
