BENTLY 1900/55 Vibration Monitor
Product Overview: BENTLY 1900/55
The BENTLY 1900/55 vibration monitor is a single-channel industrial monitoring solution designed for precise measurement of shaft vibration in rotating machinery. As a core component of Bently Nevada’s 1900 Series, this monitor provides critical vibration analysis for small to medium-sized equipment, enabling early detection of mechanical issues such as imbalance, misalignment, or bearing wear. Engineered for reliability in industrial environments, the 1900/55 combines advanced signal processing with a rugged design to deliver accurate vibration measurements that support predictive maintenance and minimize unplanned downtime.
Featuring a compact 19-inch rack-mount form factor, the 1900/55 interfaces seamlessly with proximity probes (e.g., 106M1081-01) and extension cables (e.g., 135489-03) to convert mechanical vibrations into electrical signals for analysis. Its analog output (4–20 mA) and alarm relay functions enable integration with PLCs, DCS systems, and SCADA platforms, making it an essential component for automation setups that require real-time vibration monitoring. The monitor’s -40°C to +70°C operating temperature range and IP20 protection rating ensure durability in harsh industrial settings, from manufacturing plants to power generation facilities.
In automation systems, the 1900/55 serves as a cost-effective solution for basic vibration monitoring, particularly in applications where full-scale monitoring systems are unnecessary. Its user-friendly interface and straightforward configuration simplify installation and operation, while its compatibility with Bently Nevada’s broader ecosystem of probes and modules allows for system expansion as needs evolve.

Main Features and Advantages: BENTLY 1900/55
Precision Vibration Analysis: The 1900/55 utilizes eddy current technology to measure shaft vibration with high accuracy, enabling early detection of minor anomalies that could escalate into major failures. Its 0–500 µm measurement range suits most industrial rotating equipment, from pumps to small turbines.
Simplified Integration: With standard 4–20 mA analog outputs and relay contacts, the monitor integrates seamlessly with existing control systems, reducing the need for specialized interfaces. This compatibility makes it ideal for retrofitting into older automation setups or the needs of small-scale operations.
Rugged Industrial Design: Built with a metal enclosure and IP20 protection, the 1900/55 withstands dust, moisture, and mechanical stress common in industrial environments. Its wide temperature range ensures reliable operation in both harsh outdoor settings and high-temperature processing areas.
User-Friendly Operation: The monitor’s front-panel indicators and straightforward configuration menu allow operators to quickly set alarm thresholds and view real-time vibration data without extensive training. This simplicity minimizes setup time and reduces the risk of operational errors.
Cost-Effective Solution: As a single-channel monitor, the 1900/55 offers a cost-effective entry point to vibration monitoring for small businesses or applications with limited monitoring needs. Its modular design also allows for cost-efficient system expansion by adding additional channels as requirements grow.
