990-05-XX-01-00 ( MOD: 289549-01) | Bently | 2-Wire Vibration Transmitter

Bently Nevada is a global leader in industrial asset condition monitoring and protection, specializing in vibration, pressure, and speed measurement solutions for critical machinery. Founded in 1956 by Don E. Bently, the company pioneered eddy-current proximity probes, revolutionizing rotor dynamics monitoring. Acquired by GE in 2002, Bently Nevada operates in over 50 countries, serving industries such as oil & gas, power generation, and mining. Its product portfolio includes sensors, monitoring systems like the 3500 Series, diagnostic instruments, and predictive maintenance software such as System 1. With over 25,000 customers worldwide, the company combines more than 60 years of expertise with cloud-connected solutions to enhance asset reliability and operational safety.

The Bently 990-08-XX-01-00 MOD167541-12 is a high-precision axial position transmitter designed for monitoring and protecting rotating machinery such as turbines, compressors, and pumps in industries like oil & gas, power generation, and steel manufacturing. It utilizes non-contact eddy current measurement technology to provide accurate shaft displacement readings with a typical sensitivity of 7.87 mV/μm (200 mV/mil) and a linear range of 2 mm. The device integrates Proximitor sensor technology, eliminating the need for external signal conditioning, and outputs a 4-20 mA proportional signal for integration with control systems like PLCs or DCS. Its robust construction ensures reliable performance even in harsh environments, with operational temperatures ranging from -35°C to +85°C and resistance to high humidity.

Key features include self-diagnostic fault detection, DIN rail or panel mounting options, and compliance with ATEX, CSA, and CE certifications for hazardous area applications. The transmitter supports real-time monitoring of axial movement, enabling early fault detection and preventing catastrophic machinery failures. It is compatible with Bently Nevada’s 3300 XL proximity probe systems, ensuring seamless integration into existing vibration monitoring setups. Additionally, its test input pins allow quick loop verification, while the Prox Out terminal provides dynamic vibration signals for diagnostic purposes.
