Product Overview
The 3500/22-01-01-00 is a high-performance vibration monitor module within Bently Nevada’s 3500 Machinery Protection System, engineered to deliver precise, real-time measurements of rotating machinery vibration—one of the most critical indicators of equipment health. As a key member of the 3500/22 series, this module is designed to continuously monitor vibration levels in assets like turbines, compressors, and pumps, converting raw sensor data into actionable insights that help prevent catastrophic failures.
In industrial setups, the 3500/22-01-01-00 acts as a vigilant sentinel, tracking parameters such as radial and axial vibration, as well as shaft displacement, against user-defined thresholds. When anomalies are detected—like excessive vibration from bearing wear or rotor imbalance—the module triggers alerts or shutdowns to protect equipment. Its seamless integration with the 3500 chassis and compatibility with the 3500/20 interface module ensure data flows efficiently to control systems, making it a cornerstone of predictive maintenance strategies. What sets the 3500/22-01-01-00 apart is its balance of precision and ruggedness, performing reliably even in harsh environments where temperature fluctuations and electrical noise are common.

Key Features and Benefits
The 3500/22-01-01-00 stands out for its multi-channel capability, monitoring up to four proximity probes simultaneously to capture a comprehensive view of machinery health. This allows it to detect a range of issues—from rotor imbalance and misalignment to bearing degradation—with exceptional accuracy, thanks to its broad frequency response that captures both low-speed movement and high-frequency vibration.
A critical advantage of the 3500/22-01-01-00 is its integrated diagnostic suite. It performs continuous self-tests and identifies sensor faults (e.g., broken cables or probe misalignment), reducing false alarms and ensuring operators trust the data. Its relay outputs enable immediate action, triggering alerts or safety shutdowns when vibration exceeds user-set thresholds, preventing costly damage.
Seamless integration with the 3500 chassis and 3500/20 interface module ensures data flows efficiently to DCS or SCADA systems, making it easy to incorporate into existing monitoring ecosystems. The module’s rugged design, resistant to electrical noise and temperature swings, ensures reliable performance in harsh industrial environments, from refineries to power plants.
Application Scenarios
The 3500/22-01-01-00 is indispensable in industries where rotating machinery is critical. In power generation, it monitors steam and gas turbines, tracking shaft vibration to detect imbalances that could lead to turbine failure during peak demand. By alerting operators to subtle changes, it enables maintenance before a breakdown disrupts electricity supply.
In oil and gas refineries, the 3500/22-01-01-00 safeguards centrifugal compressors, which operate under high pressure. It detects vibration caused by worn impellers or misaligned shafts, preventing seal failures that could leak hydrocarbons and halt production. For offshore platforms, its reliability in humid, corrosive environments makes it a trusted choice for monitoring subsea pump vibration.
Chemical processing plants use the 3500/22-01-01-00 to monitor agitators and mixers, ensuring consistent vibration levels that indicate proper alignment. This protects against uneven mixing, which can compromise product quality, and prevents motor damage from excessive vibration.
