The Emerson CSI 2140, also branded as the AMS 2140 Machinery Health Analyzer, is a high-performance portable vibration data collector and machinery diagnostic instrument built for predictive maintenance and route-based condition monitoring. Developed by Emerson, this field analyzer is widely trusted by reliability engineers to capture vibration, phase, and dynamic machine data across rotating assets, enabling early fault identification before catastrophic downtime occurs. It succeeds the proven CSI 2130 platform and retains all its core functions while adding upgraded speed, multi-channel capability and enhanced PeakVue analytics for bearing and gearbox diagnostics.

The CSI 2140 supports simultaneous four-channel vibration acquisition plus phase measurement, drastically speeding up route collection work. Instead of single-channel sequential sampling, it captures cross-channel data synchronously, making it ideal for advanced diagnostics including cross-phase analysis, transient capture, order tracking and multi-plane field balancing. Its standout feature is Emerson’s patented PeakVue™ technology, which isolates high-frequency stress waves generated by early rolling-element bearing and gear degradation. Unlike standard vibration spectrum tools that only catch late-stage faults, PeakVue detects incipient impacts long before measurable vibration levels rise, giving maintenance teams ample lead time to schedule repairs and avoid unplanned shutdowns.

This portable analyzer covers an extremely broad frequency bandwidth, supporting both low-speed assets and high-speed critical machinery. It delivers accurate readings down to low frequencies for slow rotating equipment while reaching up to 80,000 Hz, which is essential for centrifugal compressors, high-speed expanders and gearboxes. It ships with a large, sunlight-readable color touchscreen, backlit physical keys, generous onboard memory, and a rugged sealed housing rated for demanding plant environments. Certified for hazardous locations with ATEX, IECEx and CSA approvals, it can safely operate inside classified zones found in refineries, petrochemical plants and grain-handling facilities.

Onboard embedded analysis tools eliminate the need to send every dataset back to the office for review. The CSI 2140 includes waveform autocorrelation, fault frequency overlays, narrow-band trending, coast-down testing, bump tests, time synchronous averaging, MCSA motor current signature analysis and high-resolution spectrum capture. It supports triaxial accelerometer workflows, cutting route data collection time by approximately 30% for routine asset surveys. It can also integrate seamlessly with Emerson AMS Suite software for centralized data storage, trending, reporting and enterprise reliability management.

Common Applications

The Emerson CSI 2140 is deployed across all industries with critical rotating equipment: steam turbines, gas turbines, centrifugal compressors, screw compressors, large process pumps, fans, blowers, gearboxes, electric motors and expanders. Reliability teams use it for routine route-based condition monitoring, troubleshooting abnormal vibration, performing field dynamic balancing, validating laser alignment jobs, investigating motor electrical faults and auditing bearing health. It is heavily used in thermal power plants, combined-cycle facilities, oil refineries, petrochemical complexes, LNG terminals, offshore platforms, pulp and paper mills, mining sites and food processing plants. It is a popular spare and rental-grade instrument for reliability service companies, maintenance contractors and plant in-house predictive maintenance programs.
