The Bently Nevada 21747-040-00 Extension Cable is used to extend the electrical connection between proximity probes and Proximitor or monitoring systems. It ensures accurate, low-noise transmission of vibration and displacement signals in rotating machinery, enabling reliable condition monitoring and protection of critical industrial equipment.
The Bently Nevada 21747-040-00 Extension Cable has the following core parameters: it is a 4.00 m (157 in) extension cable designed for Bently Nevada vibration monitoring systems, supplied in a non-armored configuration. It operates within a power range of -17.5 Vdc to -26 Vdc at 12 mA and supports a frequency response from 0 Hz (DC) to 10 kHz for accurate signal transmission. The probe and cable assembly is rated for an operating temperature range of -34°C to +177°C (-309°F to +350°F), ensuring suitability for harsh industrial environments. It is manufactured in the USA and commonly shipped from Xiamen, China, providing reliable signal extension for industrial rotating machinery monitoring applications.
The Bently Nevada 21747-040-00 Extension Cable is a rugged industrial-grade interconnect component designed for long-distance signal transmission in vibration monitoring systems. It is built to maintain signal integrity between proximity probes and monitoring modules even in electrically noisy and mechanically demanding environments. Widely used in power generation, oil & gas, petrochemical, and heavy industrial applications, it supports continuous monitoring of turbines, compressors, pumps, and other rotating machinery, helping ensure equipment reliability and enabling predictive maintenance strategies.
