Bently Nevada 21747-045-01 Extension Cable

21747-045-01 Bently Nevada 4.5m Armored Extension Cable

Product Introduction

The Bently Nevada 21747-045-01 extension cable serves as a critical component in the 3300 XL proximity monitoring system. This 4.5-meter cable bridges the gap between the probe assembly and the Proximitor sensor, completing the measurement circuit. Meanwhile, its armored construction provides superior protection against physical damage in harsh industrial environments. Specifically, this cable is designed to work seamlessly with Bently Nevada probes and Proximitors of matching lengths. Furthermore, the 21747-045-01 comes brand new in factory-sealed packaging, backed by a 12-month manufacturer warranty. Therefore, this extension cable ensures reliable signal transmission for critical vibration and position monitoring applications.

Technical Specifications

This 21747-045-01 extension cable offers a precise length of 4.50 metres (177 inches) , suiting medium-range installation requirements. In addition, the 045 length option indicates this specific 4.5-metre configuration. Moreover, the 01 armor option confirms the inclusion of stainless steel armor, which delivers enhanced resistance to physical abuse and mechanical stress. The complete system—comprising probe, extension cable, and Proximitor—achieves a total length of either five or nine metres from probe tip to Proximitor. Consequently, this standardized approach ensures complete interchangeability among probes and cables of the same length.

Electrical Performance

The Bently Nevada 21747-045-01 extension cable operates within a well-defined electrical framework. Specifically, the system input requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. For output performance, the calibrated range spans 80 mils (2.0 mm) , beginning at approximately 10 mils (0.25 mm) from the probe face. Furthermore, the scale factor measures 200 mV/mil (7.87 V/mm) with ±4% accuracy when calibrated as a system, or ±9.5% including interchangeability errors. Meanwhile, linearity remains within 0.8 mils (0.02 mm) for system-calibrated configurations, or within 2.3 mils (0.06 mm) including interchangeability errors. Additionally, frequency response extends from 0 to 10 kHz (0 to 600,000 cpm) , with only -5% attenuation at 10 kHz.

Environmental and Mechanical Ratings

The 21747-045-01 extension cable demonstrates robust environmental tolerance across various operating conditions. For the Proximitor, the operating temperature ranges from -60°F to +212°F (-51°C to +100°C) . Meanwhile, the probe and extension cable withstand temperatures from -30°F to +350°F (-34°C to +177°C) . Moreover, this cable supports relative humidity up to 95% , non-condensing, ensuring reliable operation in humid environments. For corrosion resistance, 8 mm probe operation remains unaffected by direct contact with air, water, lube oil, ammonium hydroxide, 10% sulfuric acid, MEK, or DMF. Therefore, this extension cable proves suitable for demanding chemical and petrochemical applications.

Installation Guidelines

When installing the 21747-045-01 extension cable, technicians should follow several best practices carefully. First, ensure all connectors are clean and free from debris before making connections. Next, verify that the cable length matches your system configuration requirements. Furthermore, handle the armored cable with care during routing, avoiding sharp bends or excessive tensile stress. Meanwhile, secure the cable at regular intervals to prevent mechanical strain on the connectors. In addition, always pair this cable with probes and Proximitors of matching lengths to maintain system interchangeability. For this reason, the Bently Nevada system design ensures that all components with the same part number are completely interchangeable.

Packaging and Logistics

Each unit of the Bently Nevada 21747-045-01 arrives in original factory packaging, guaranteeing authenticity and protection. Specifically, the packaging includes the extension cable itself with stainless steel armor intact. We also ensure the cable is coiled and secured properly to prevent kinking or damage during transit. Moreover, all orders are dispatched using premium, expedited shipping services. Therefore, we partner with global carriers such as FedEx, UPS, and DHL. Consequently, your critical cable component arrives safely and promptly, ready for immediate installation.
