330130-035-12-00 Bently Nevada 3.5m Proximity Cable

Bently Nevada 330130-035-12-00 Armored FluidLoc Extension Cable

Product Introduction

This Bently Nevada 330130-035-12-00 extension cable offers a compact solution for proximity monitoring systems. It connects non-contacting probes to Proximitor sensors in space-constrained installations. Specifically, this model provides a 3.5-meter length with both armored jacketing and FluidLoc sealing. The FluidLoc feature actively prevents oil and other liquids from escaping through the cable interior. Additionally, this cable includes a connector protector for enhanced connection security. Therefore, it is particularly suitable for turbine, compressor, and pump applications where oil exposure and limited space are concerns.

Technical Specifications

The Bently Nevada 330130-035-12-00 delivers a nominal capacitance of 69.9 pF/m (21.3 pF/ft). Its center conductor DC resistance measures 0.77 ± 0.12 Ω. Meanwhile, the outer conductor resistance is 0.23 ± 0.05 Ω. The cable integrates seamlessly with Proximitor sensors that require -17.5 Vdc to -26 Vdc without barriers. Furthermore, the system output resistance is 50 Ω. The supply sensitivity remains below 2 mV change per volt of input variation.

This extension cable supports a linear range of 2 mm (80 mils). The effective measurement zone starts at approximately 0.25 mm (10 mils) and extends to 2.3 mm (90 mils). Additionally, the 3300 XL system maintains excellent stability in humid conditions. Specifically, it shows less than a 3% change in Average Scale Factor after 56 days of 93% relative humidity testing per IEC 68-2-3.

Mechanical and Environmental Features

The Bently Nevada 330130-035-12-00 includes a rugged armored jacket weighing 103 g/m (1.5 oz/ft). This armor provides exceptional protection against physical damage, crushing, and abrasion. Moreover, the cable incorporates patented CableLoc technology for 330 N (75 lbf) pull strength. This ensures the connection between probe cable and probe tip remains secure even under tension.

The defining feature of this model is the FluidLoc cable option combined with a connector protector. The FluidLoc design prevents oil migration through the cable's interior, a common failure point in standard cables. Meanwhile, the connector protector offers additional sealing at the connection point. Therefore, operators can confidently install this cable in environments with continuous oil exposure. The gold-plated ClickLoc connectors further enhance reliability by resisting corrosion and maintaining low contact resistance.

Approvals and Compliance

This 330130-035-12-00 carries the 00 approval option, indicating no hazardous area certifications are required. This makes it suitable for general-purpose industrial installations where ATEX, CSA, or IECEx approvals are not necessary. When barriers are used in the circuit, the power requirement shifts to -23 Vdc to -26 Vdc. Operation at voltages more positive than -23.5 Vdc may result in a reduced linear range. For field wiring, we recommend 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable.

Installation Guidelines

First, ensure the probe is gapped at 1.27 mm (50 mils) for optimal system performance. Next, connect the 330130-035-12-00 using the gold-plated ClickLoc connectors until they click securely. The FluidLoc design and connector protector work together to eliminate the need for additional sealing compounds. However, standard silicone tape is included for added protection if needed. For applications with turbine oil, the FluidLoc feature provides superior sealing compared to tape alone. Finally, the maximum field wiring distance between the Proximitor sensor and monitor is 305 meters (1,000 feet).

Frequently Asked Questions (FAQ)

1. What is the difference between the 330130-035-12-00 and standard extension cables?
This model includes both FluidLoc oil-sealing technology and a connector protector. The FluidLoc feature prevents oil from leaking through the cable interior, while the protector adds extra connection security.

2. Is the Bently Nevada 330130-035-12-00 approved for hazardous areas?
No. This cable carries the 00 approval option, meaning it is designed for general-purpose installations without hazardous area certifications.

3. Can I use this cable with 5 mm proximity probes?
Yes. This cable accepts 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes without any adapter.

4. Does the FluidLoc option require special maintenance?
No. The FluidLoc design is maintenance-free and requires no periodic re-sealing. Simply connect it properly and it performs continuously.

5. What is the maximum distance between sensor and monitor?
The maximum field wiring distance is 305 meters (1,000 feet). Longer distances may cause signal rolloff at high frequencies.
