At the core of the health of rotating machinery lie vibration monitoring systems—systems that play a vital role in preventing costly breakdowns, reducing unplanned downtime, and extending the service life of industrial equipment. Over the years, prominent global brands such as Bently Nevada, Brüel & Kjær (B&K), Shinkawa, Vibrometer (Meggitt), Metrix, and PVTm have set the industry standards by providing high-precision sensors and advanced monitoring systems.
However, over time, many of these models have been discontinued, or their technical support has become limited. This has created challenges for key national industries—including oil and gas, petrochemicals, steel, power plants, and refineries—regarding the procurement of spare parts and an increased risk of equipment failure. The failure of a vibration monitoring system can lead to serious damage to turbines, pumps, compressors, and generators.
As a specialized authority in the design and manufacturing of vibration measurement equipment and industrial sensors, Yekan utilizes reverse engineering and indigenous technical expertise to produce and supply a new generation of replacement products under its own proprietary brand, Yekan. These domestically manufactured alternatives correspond to equipment originally produced by international brands; they are fully compatible with the original versions in terms of mechanical dimensions, electrical parameters, sensitivity, frequency response, and environmental resistance.
While the Bently Nevada 3000 series was known for its robust design, it faces limitations regarding accuracy and frequency response in modern operational environments. Yekan has focused on developing a new generation of probes and transducers that deliver performance surpassing the 3000 series, while maintaining full compatibility with existing Bently Nevada 3000 series proximity probes, cables, and transducers.
We understand that completely replacing a proximity system can be costly. For this reason, Yekan’s new YB series (YEKAN Replacement for Bently Nevada) probes—
not only meet all technical specifications required for direct replacement of Bently Nevada 3000 series components, but also offer superior signal stability and enhanced environmental resistance. These replacements are fully compatible with your existing control and monitoring systems.
Since Bently Nevada introduced only new transducers in its 7000 series—while continuing to utilize the same probes and extension cables as the 3000 series—the Yekan engineering team conducted a detailed analysis of the 7000 series’ technical and electrical specifications. Consequently, they designed and manufactured replacement transducers that are fully compatible with Bently Nevada standards.
These transducers are designed to enhance service life and operational stability while reducing maintenance costs, serving as a reliable alternative for 7000 series transducers in vibration monitoring systems.
In the field of condition monitoring, maintaining the integrity and stability of measurement systems is critical. Given that the Bently Nevada 7200 series has been discontinued for many years, the Yekan engineering team—leveraging its specialized expertise in advanced systems—has successfully developed a comprehensive replacement for the Bently Nevada 7200 series proximity system.
This solution is not limited to a single component; rather, it is a complete system-level solution. It includes replacement transducers designed according to the precise electrical specifications of the 7200 series, ensuring reliable voltage output and the expected stability across the standard 7200 vibration ranges.
Furthermore, YEKAN’s YB-series probes and cables (YEKAN Replacement BENTLY NEVADA) feature the necessary dimensional precision and sensitivity; they are fully compatible with 7200-series holders and ensure that the sensor air gap is set in accordance with the original system’s requirements, without the need for complex adjustments.
The Bently Nevada 3300XL vibration measurement system—one of the most advanced and modern proximity measurement solutions in the industry—has set the standard for condition monitoring of rotating machinery, such as turbines, compressors, and generators. Although this series remains in active production, the high cost of original components—including probes, extension cables, and transducers—coupled with a total reliance on imports, continues to pose a significant challenge for industrial facilities in the country.
Leveraging its extensive experience in reverse engineering, the Yekan Company has developed and introduced a line of domestically manufactured, fully compatible alternatives to the 3300XL system under the brand name “Yekan” (YB Series). This series not only meets all the technical specifications of the original system but also encompasses 5mm, 8mm, 11mm, and NSV models, ensuring comprehensive coverage for the diverse equipment requirements found within the oil, gas, power generation, and petrochemical sectors.
The primary concern when replacing vibration monitoring components is maintaining the frequency response and ensuring that the sensor’s electrical specifications match precisely. For the 3300XL series, Yekan guarantees this compatibility; YB series proximity probes are designed with the same sensitivity and linear range as the original probes, while Yekan’s extension cables—manufactured with high-precision impedance control—ensure minimal signal loss along the transmission path. Furthermore, YB series transducers are fully compatible with the output format of the original systems.
A unique feature of these products is their interoperability; for instance, a YB probe can be used in conjunction with an original Bently Nevada cable and transducer—or vice versa—without any issues. This level of electrical compatibility allows users to replace only the damaged component with a locally manufactured unit, significantly reducing costs and eliminating the need for modifications to the entire system.
