Quick Detail

Description

The 21508-02-12-05-02 3300 XL 11 mm Extension Cable is a high-performance connectivity core engineered and manufactured by Bently Nevada, serving as an indispensable link in the 3300 XL 11 mm transducer system for critical industrial machinery condition monitoring. This 3300 XL 11 mm Extension Cable is specifically designed to deliver uncompromised signal integrity between 3300 XL 11 mm proximity probes and Proximitor sensors, even in the harshest industrial environments characterized by extreme temperatures, high contamination, and intense mechanical vibration. As a key upgrade component for legacy 7200-series 11 mm and 14 mm systems, the 3300 XL 11 mm Extension Cable enables seamless transition to modern monitoring setups, ensuring that vibration and axial position data remain accurate and reliable throughout the entire measurement chain.

What defines the 21508-02-12-05-02 3300 XL 11 mm Extension Cable is its rugged armored cable construction, flexible length options including a standard 8.0-meter (26.2 feet) and 5.0-meter (16.4 feet) variant, and multiple global agency approvals that support deployment across diverse international industrial sites. Built to resist lubricating oil ingress, moisture corrosion, and industrial solvent damage, the 3300 XL 11 mm Extension Cable features a factory-installed environmental seal that protects the connection point from contamination, eliminating signal drift and intermittent grounding faults common in wet bearing housings and turbine enclosures. With an operating and storage temperature range of -50°C to +170°C (-65°F to +355°F), this 3300 XL 11 mm Extension Cable maintains stable electrical properties even when routed alongside high-pressure steam lines or in thermal hot zones where standard coaxial cables would fail.

Applications

The 21508-02-12-05-02 3300 XL 11 mm Extension Cable is widely applied in power generation plants, serving as the critical signal link between 3300 XL 11 mm proximity probes and monitoring racks in steam and gas turbines. Its armored construction and environmental connector seal resist oil mist and high temperatures in turbine enclosures, while its 8.0-meter length enables flexible routing from hard-to-reach bearing housings to control rooms, ensuring accurate vibration data collection to prevent turbine failures and unplanned power outages.

In the oil and gas sector, this extension cable plays a vital role in offshore drilling platforms and onshore refineries, connecting proximity probes on centrifugal compressors and pipeline pumps to Proximitor sensors. Its multiple global approvals allow deployment in hazardous Zone 1/2 areas with flammable gases, and its low capacitance minimizes signal degradation over long distances, providing reliable data for predictive maintenance and ensuring the safety of critical hydrocarbon processing equipment.

This 3300 XL 11 mm Extension Cable is also an essential component in petrochemical manufacturing facilities, where it is used to transmit signals from proximity probes installed on mixers, reactors, and agitators. Its compatibility with 0.1 to 1.4 mm² field wiring simplifies integration with plant DCS systems, and its superior electrical noise immunity ensures stable data transmission even in environments with dense variable frequency drives (VFDs) and high-voltage equipment, supporting precise process control and asset protection.

Specifications

Competitive Advantage

1.Rugged Armored Construction with Integrated Environmental Sealing

The 21508-02-12-05-02 3300 XL 11 mm Extension Cable features a heavy-duty armored cable design paired with a factory-installed connector protector, creating a hermetic seal that prevents oil, moisture, and solvent ingress. Unlike standard extension cables that suffer from signal drift and corrosion in wet industrial environments, this design ensures long-term signal stability and drastically reduces the risk of false machine trips, making it ideal for internal bearing housing installations in turbines and compressors.

2.Global Multi-Agency Approvals for Hazardous Area Deployment

Equipped with multiple international certifications, this extension cable is compliant for use in Zone 0/1/2 hazardous areas across the globe, eliminating the need for multinational industrial users to source region-specific cable variants. This global interoperability simplifies procurement logistics and ensures compliance with strict safety standards in oil & gas, petrochemical, and mining industries, providing a one-stop connectivity solution for cross-border projects.

3.Extreme Temperature Tolerance and Signal Stability

Rated for continuous operation from -50°C to +170°C, the 3300 XL 11 mm Extension Cable outperforms standard industrial cables that become brittle or melt in extreme thermal conditions. Its stable electrical properties—including 45 Ω output resistance and 67.9 pF/m typical capacitance—ensure consistent voltage-to-gap ratio accuracy even during intense thermal cycling, maintaining reliable signal transmission in turbine hot zones and cryogenic processing facilities without calibration drift.
