The CSI 2140 Machinery Health Analyzer (Ex-Rated series) is the industry standard for high-performance vibration data collection and analysis in hazardous environments. These units are specifically engineered for Zone 2 explosive atmospheres, ensuring that technicians can perform critical diagnostic work safely without the need for a “hot work” permit. The device is built around a large, sunlight-readable touchscreen that allows for easy navigation even when wearing gloves.
The primary difference between these three models is the number of simultaneous measurement channels. The A21401 (1-channel) is ideal for basic route collection, while the A21402 (2-channel) and A21404 (4-channel) significantly reduce time spent on-site by allowing for cross-channel phase analysis and simultaneous triaxial measurements. All models feature Emerson’s patented PeakVue technology, which provides the earliest possible indication of bearing and gearbox wear by filtering out low-frequency vibration to focus on high-frequency stress waves.
The ruggedized housing is designed to withstand the rigors of industrial use, featuring an ergonomic design that balances weight for comfortable all-day operation. With the integrated analysis experts, users can perform advanced troubleshooting—including resonance testing and balancing—directly on the shop floor. This connectivity ensures that data can be uploaded wirelessly to the Machinery Health Manager software for long-term trend analysis and reporting.
To help you maximize the reliability of your hazardous-area assets, I-care engineers are available to provide professional support. Our experts offer technical advice on establishing optimal vibration routes and interpreting complex PeakVue patterns to prevent catastrophic failures. By utilizing the CSI 2140 Ex-Rated series and following I-care’s engineering guidance, you can ensure your predictive maintenance program remains safe, efficient, and highly accurate.
