Bently Nevada 330130-085-03-05 Extension Cable 8.5m

Product Introduction

This Bently Nevada 330130-085-03-05 extension cable is a critical component for 3300 XL vibration monitoring systems. Firstly, its 8.5-meter length provides flexibility for various machine installations. Moreover, the cable's armored construction ensures durability and resistance to physical damage in industrial environments.

Technical Specifications

Electrical and Physical Parameters
The Bently Nevada 330130-085-03-05 offers specific electrical characteristics for reliable signal transmission. For instance, the nominal DC resistance from center conductor to center conductor is 1.87 ± 0.28 Ω. Meanwhile, the resistance from outer conductor to outer conductor is 0.56 ± 0.11 Ω. Additionally, the extension cable has a typical capacitance of 69.9 pF/m (21.3 pF/ft). This cable, when combined with a probe, must match the total length required by the Proximitor Sensor.

Length and Options
The cable length option "085" denotes 8.5 meters (27.9 feet). Furthermore, the "03" option specifies an armored cable with a connector protector. Consequently, this provides enhanced protection against oil and physical stress. The 3300 XL extension cable also includes silicone tape as an alternative to connector protectors. However, we do not recommend silicone tape for applications involving turbine oil exposure.

Environmental and Approvals
Notably, the "05" approval option grants this cable CSA, ATEX, and IECEx certifications. Therefore, it is suitable for use in hazardous areas and various global industrial applications.

Mechanical and Installation Details

Physical Weight and Pull Strength
The standard extension cable weighs 0.289 kg. However, this armored version weighs 0.875 kg due to its robust shielding. The 3300 XL probe and cable design incorporate a patented CableLoc method. This provides a pull strength of 330 N (75 lbf). As a result, it securely attaches the probe cable and probe tip.

Installation Considerations
When installing, ensure that the extension cable length and the probe length add up to the Proximitor Sensor's total length. This system uses a -17.5 Vdc to -26 Vdc power supply, with a maximum current consumption of 12 mA. Moreover, using a voltage more positive than -23.5 Vdc can reduce the linear range. For field wiring, we recommend using 3-conductor shielded triad cable of 0.2 to 1.5 mm2 (16 to 24 AWG). The maximum length between the sensor and monitor is 305 meters (1,000 feet).

FluidLoc Option
Furthermore, users can order 3300 XL 8 mm probes and extension cables with an optional FluidLoc cable option. Specifically, this prevents oil and other liquids from leaking out of the machine through the cable’s interior.

Performance and Accuracy

Linear Range and Sensitivity
The system's linear range starts at approximately 0.25 mm (10 mils) from the target. It extends from 0.25 to 2.3 mm (10 to 90 mils), corresponding to -1 to -17 Vdc. The power supply sensitivity is less than 2 mV change in output per volt change in input. Additionally, the output resistance is 50 Ω. These specifications apply with a -24 Vdc supply, a 10 kΩ load, and an AISI 4140 steel target.

System Accuracy
All performance characteristics apply to systems consisting solely of 3300 XL 8 mm components. The system accuracy and interchangeability specifications do not apply to systems calibrated to targets other than the AISI 4140 steel target. Therefore, correct target material is crucial for accurate readings.

Environmental Stability
The Bently Nevada 3300 XL system shows high stability in harsh conditions. For example, the Average Scale Factor (ASF) changes by less than 3% when tested in 93% humidity according to IEC standard 68-2-3 for up to 56 days.

Frequently Asked Questions (FAQ)

1. What is the total weight of the Bently Nevada 330130-085-03-05 armored cable?
The armored version weighs approximately 0.875 kg, while the standard unarmored version weighs 0.289 kg.

2. Can I use silicone tape with this extension cable in a turbine oil environment?
We do not recommend using silicone tape for applications where the connection will be exposed to turbine oil. The connector protector is the preferred solution for such environments.

3. How do I calculate the correct total length for my proximity system?
Make sure that the length of your probe and the length of your extension cable, when added together, equal the Proximitor Sensor total length specified for your system.

4. What type of field wiring is suitable for this extension cable?
We recommend using 3-conductor shielded triad cable, with a conductor size of 0.2 to 1.5 mm2 (16 to 24 AWG).

5. What are the "03" and "05" options in the product number?
The "03" option denotes that the cable is armored and includes a connector protector. The "05" option indicates that the cable has CSA, ATEX, and IECEx approvals for use in hazardous areas.
