1. Product Overview and Key Features
The Bently Nevada 4351B is a high-performance vibration sensor designed for industrial automation and machinery health monitoring. As part of the 4300 Series, this rugged accelerometer excels in harsh environments, offering reliable measurement of vibration, acceleration, and dynamic motion in rotating equipment. Its robust stainless steel housing ensures durability in extreme temperatures, corrosive atmospheres, and high-humidity conditions. The 4351B delivers a 4-20 mA output signal, compatible with most control systems, and features a wide frequency range (5 Hz to 10 kHz) for detecting both low-speed and high-frequency anomalies. With integrated electronics for signal conditioning, it simplifies installation while maintaining accuracy for predictive maintenance programs.
2. Technical Specifications and Certifications
Engineered for precision, the 4351B operates within a -40°C to 85°C temperature range and withstands shocks up to 100 g. It offers a linear dynamic range of ±50 g, ideal for capturing subtle vibration changes indicative of bearing wear, imbalance, or misalignment. The sensor meets global certifications, including ATEX/IECEx for hazardous areas, and complies with ISO 10816 vibration severity standards. Its hermetically sealed design (IP67 rating) prevents moisture ingress, making it suitable for offshore platforms, power plants, and chemical processing facilities. Optional mounting configurations, such as stud or magnetic bases, enhance flexibility across applications like turbines, pumps, and compressors.
3. Applications and Industry Benefits
The 4351B is critical for asset protection and operational efficiency in industries such as oil and gas, energy, and manufacturing. By integrating with condition monitoring systems like System 1™, it enables real-time diagnostics to prevent unplanned downtime. Its low-power design ensures compatibility with remote monitoring setups, while minimal maintenance requirements reduce lifecycle costs. The sensor’s ability to detect early-stage mechanical faults supports predictive maintenance strategies, extending equipment lifespan and optimizing safety. Trusted globally, the 4351B exemplifies Bently Nevada’s legacy in delivering scalable solutions for critical infrastructure reliability.
