Bently Nevada 330130-075-03-05 Extension Cable

Bently Nevada 330130-075-03-05 Extension Cable

Product Introduction

The Bently Nevada 330130-075-03-05 is a high-performance extension cable specifically engineered for the 3300 XL 8 mm proximity transducer system. This extension cable provides a critical link between the non-contacting probe and the Proximitor sensor. Its armored construction offers superior mechanical protection in demanding industrial environments. Moreover, this cable carries hazardous area approvals for global installation flexibility. This cable is essential for accurate vibration and position measurements on turbines, compressors, and other rotating machinery.

Technical Specifications

The 330130-075-03-05 cable offers precise electrical characteristics and robust mechanical design. Its specifications ensure system accuracy and long-term reliability.

• Cable Length: 7.5 meters (24.6 feet)

• Cable Type: Armored cable with connector protector

• Connector Type: Corrosion-resistant, gold-plated ClickLoc connectors

• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical

• Center Conductor DC Resistance (RCORE): 1.65 ± 0.25 Ω

• Outer Conductor DC Resistance (RJACKET): 0.49 ± 0.10 Ω

• Probe Compatibility: Accepts 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probes

• Cable Pull Strength: 330 N (75 lbf) with CableLoc design

• Approvals: CSA, ATEX, IECEx (hazardous area certified)

Additionally, this cable includes silicone tape for connection sealing. However, we do not recommend using silicone tape in applications exposed to turbine oil. For such cases, the FluidLoc cable option offers a superior sealing solution.

Mechanical and Environmental Parameters

The Bently Nevada 330130-075-03-05 is built to withstand harsh conditions. Its materials and construction ensure reliable performance over extended periods.

• Weight (Standard): 34 g/m (0.4 oz/ft); total 0.204 kg

• Weight (Armored): 103 g/m (1.5 oz/ft); total 0.618 kg

• Operating Temperature: -51°C to +177°C (-60°F to +350°F)

• Humidity Resistance: Less than 3% change in Average Scale Factor after 56 days at 93% humidity (per IEC 68-2-3)

• Pressure Seal Material: Viton® O-ring (probe tip sealing)

• Maximum Altitude: 2000 meters for specified performance

Furthermore, the patented TipLoc molding method provides a robust bond between the probe tip and body. This design significantly improves durability compared to previous generations. The armored jacket also protects against abrasion and impact damage in field installations.

Installation and Compatibility Guidelines

Installing the 330130-075-03-05 correctly is crucial for system performance. First, connect the cable securely to both the probe and the Proximitor sensor using the gold-plated ClickLoc connectors. These connectors ensure a corrosion-resistant, reliable electrical connection.

Next, verify that the total system length matches your application requirements. This extension cable is compatible with 3300 XL 8 mm probes and sensors exclusively. For field wiring between the Proximitor sensor and monitor, use 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable. The maximum field wiring length is 305 meters (1,000 feet). However, note that longer lengths may cause signal rolloff at high frequencies.

Finally, consider the power supply requirements. The Proximitor sensor requires -17.5 Vdc to -26 Vdc without barriers. With barriers, it needs -23 Vdc to -26 Vdc. Operation at voltages more positive than -23.5 Vdc can reduce the linear range.

Frequently Asked Questions (FAQ)

1. What approvals does the 330130-075-03-05 carry?
The Bently Nevada 330130-075-03-05 holds CSA, ATEX, and IECEx certifications, making it suitable for installation in hazardous area environments worldwide.

2. What is the difference between the "03" and "13" cable options?
The "03" option, as found on 330130-075-03-05, specifies armored cable with a connector protector. The "13" option specifies armored FluidLoc cable, which includes additional fluid sealing capability.

3. Can I use this extension cable with a 3300 5 mm probe?
Yes, the Bently Nevada 330130-075-03-05 is compatible with 3300-series 5 mm probes, as well as 3300 8 mm and 3300 XL 8 mm probes.

4. Why does the cable include silicone tape, and when should I avoid using it?
The silicone tape serves as an alternative to connector protectors. However, we do not recommend using silicone tape in applications where the connection point will be exposed to turbine oil, as it may degrade over time.

5. What is the maximum field wiring length between the sensor and the monitor?
The maximum recommended field wiring length is 305 meters (1,000 feet). Using longer lengths may affect the frequency response and cause signal attenuation at higher frequencies.
