Description

The OMSD-02 is a multi-channel information-measurement system purpose-built to measure the root-mean-square (RMS) value of vibration acceleration during the diagnostics of mechanical assemblies across all classes of railway rolling stock — freight wagons, passenger coaches, locomotives, and electric multiple units. Developed and manufactured by DIATECH LLC of Nizhny Novgorod, the system has been in continuous operation throughout the Russian railway network since 2005, and is officially registered in the JSC Russian Railways measuring instruments registry under № MT 017.2013.

It carries Gosstandart of the Russian Federation certification (certificate RU.C.28.011.A № 31257, registration № 37486-08). Each of the 16 measurement channels incorporates a piezoelectric vibration transducer (AR 57), a charge amplifier (OSA-8), and an analog-to-digital converter (L-791) connected to a PC.

The system covers a working frequency range of 5 to 8,000 Hz and an RMS vibration acceleration range of 0.2 to 350 m/s². A built-in network interface enables remote fault detection, software updates, and statistical consolidation of diagnostic results from all connected units through a centralized Diagnostic Center.

Systems based on the OMSD platform are today deployed across 42 locomotive, 77 freight-wagon, 35 passenger-car, and 19 multiple-unit depots on the Russian railway network, as well as at repair facilities in Kazakhstan.

Features

🔬

16-Channel Measurement

Supports up to 16 simultaneous vibration measurement channels, each built around a piezoelectric sensor AR 57, charge amplifier OSA-8, and ADC L-791 connected to a single PC.

📡

Wide Frequency Coverage

Operating range of 5 to 8,000 Hz, with RMS acceleration measurement error not exceeding ±11% across 5–1,000 Hz and ±20% across 1,000–8,000 Hz.

📊

High-Accuracy Acceleration Sensing

Amplitude range of 0.2 to 350 m/s² for RMS vibration acceleration; channel reading variation does not exceed 2.5%, and reading instability over 8 hours of continuous operation stays within 1.5%.

🌐

Remote Network Monitoring

Built-in networking allows remote defect detection, firmware updates, and aggregation of diagnostic statistics from all networked OMSD-02 units via a centralized Diagnostic Center.

🏗️

Flexible Modular Architecture

Functional blocks are configurable for specific inspection tasks; one workstation can simultaneously serve up to 16 test benches, keeping per-bench hardware costs low.

✅

State Certification & Registry

Certified by Gosstandart of the Russian Federation (certificate RU.C.28.011.A № 31257, reg. № 37486-08) and entered in the JSC RZhD measuring instruments registry under № MT 017.2013.

Buyer Benefits

No specialized operator training is required — the system autonomously manages the full diagnostic workflow from data acquisition to result output.
A single PC can drive up to 16 test benches simultaneously, reducing infrastructure investment per inspection bay.
Continuous diagnostic database accumulation enables residual-life prediction and transition to condition-based maintenance strategies.
Centralized remote Diagnostic Center access gives depot supervisors real-time visibility across all connected branch units without on-site travel.
Integrated self-diagnostics module (released 2019) confirms system operability within 10 seconds and localizes any fault for immediate maintenance action.
Over two decades of field-validated reliability across the entire Russian railway network, covering all rolling-stock types and workshop environments.
Accepted for use at JSC RZhD facilities and recognized under EAEU technical regulations, meeting the compliance requirements of Russia and CIS partner states.

Applications

Vibration diagnostics of axle-box bearings on freight, passenger, and locomotive wheel sets at rolling-bearing workshops Condition assessment of traction motor bearings during planned maintenance at locomotive depots Inspection of wheel-set reduction gearboxes on electric multiple units and passenger wagons Bench testing of repaired rolling-stock components prior to return-to-service acceptance Stationary vibro-diagnostic stands in locomotive and wagon repair depots Continuous remote condition monitoring of distributed depot fleets via centralized Diagnostic Center Statistical fleet-wide data collection for residual-life analysis and predictive maintenance planning Quality-control testing at wagon-building and overhaul plants during new-production or post-repair acceptance
