Product Advantages
Armored Mechanical Protection
The armored cable design provides superior resistance to abrasion, crushing, vibration, and accidental mechanical impact, extending service life in demanding industrial environments.
Excellent Signal Integrity
The shielded coaxial construction helps reduce electromagnetic interference and preserves the quality of the proximity probe signal, ensuring accurate machine condition measurements.
Factory-Length Calibration
The 4.5-meter cable length is designed to match compatible transducer system configurations. Maintaining the correct total probe and extension cable length is essential for preserving factory calibration and measurement accuracy.
Flexible Installation
The extended cable length enables Proximitor sensors to be mounted away from high-temperature or high-vibration locations while maintaining reliable communication with the installed probe.
Proven Industrial Reliability
Manufactured for continuous-duty service, the cable supports long-term operation in rotating machinery monitoring systems with minimal maintenance requirements.
Technical FAQs
1. What is the Bently Nevada 21747-045-01 used for?
It connects a proximity probe to a Proximitor® sensor in a Bently Nevada proximity transducer system for vibration and displacement monitoring.
2. What does the "045" option indicate?
It specifies a 4.5-meter (177-inch) extension cable.
3. What does the "01" suffix mean?
The 01 option identifies the armored cable configuration, providing additional mechanical protection.
4. Which monitoring systems are compatible?
The cable is commonly used with 7200 Series and selected 3300 Series proximity transducer systems.
5. Can the cable be shortened?
No. The cable length is part of the transducer system calibration and should not be modified.
6. What type of connectors are used?
The cable is equipped with miniature coaxial connectors for secure connection between compatible probes and Proximitor sensors.
7. Why is shielding important?
Shielding minimizes electromagnetic interference and helps ensure accurate signal transmission in industrial environments.
8. Is this cable suitable for harsh industrial environments?
Yes. The armored construction provides excellent protection against abrasion, vibration, and mechanical damage.
9. Does the extension cable influence system accuracy?
Yes. The combined probe and extension cable length must match the Proximitor sensor configuration to maintain factory calibration.
10. Which equipment commonly uses this extension cable?
It is widely installed on turbines, compressors, generators, pumps, motors, and other rotating machinery equipped with Bently Nevada proximity monitoring systems.
