NVA-RM

Advanced System for Dynamic and Acoustic Monitoring of Rotating Machinery

NVA-RM is WinTek’s dedicated solution for continuous monitoring, advanced dynamic analysis, and acoustic diagnostics of rotating machinery, including pumps, compressors, turbines, generators, alternators, and complex industrial rotating equipment.
A flexible and scalable system based on high-performance NI hardware platforms and a powerful Real-Time engine, designed to deliver accurate measurements, reliable diagnostics, and advanced analysis both in real-time and post-processing.

  • NVA-RM is engineered for condition monitoring, vibration diagnostics, and advanced acoustic analysis. The suite integrates:

    • High-frequency multi-sensor acquisition

    • Real-Time and post-process analysis

    • Advanced alarm and anomaly detection

    • Industrial integration for automated test environments

    The system is suitable for test rooms, critical rotating assets, and industrial applications requiring maximum reliability and diagnostic depth.

  • Supported Platforms

    NVA RM is compatible with several NI hardware families:

    • NI cDAQ multi-channel systems

    • NI cRIO Real-Time systems

    • NI PXI high-performance multi-channel systems

    Supported Sensors

    Depending on the chosen hardware configuration, NVA RM can manage virtually any industrial transducer, including:

    • Accelerometers

    • Velocimeters

    • Eddy current probes

    • Key-Phasor sensors

    • RTDs and Thermocouples

    • Strain-gage sensors, load cells, torsional sensors

    • Any extensometric-based transducer

    Transducer and Channel Setup

    A dedicated setup interface allows complete definition of:

    • Transducer characteristics

    • Scaling and engineering units

    • Filters, integrations, and conditioning

    • Acquisition and logging parameters

  • The system can send and receive metrics, calculated parameters, and alarms through:

    • CAN Bus

    • MODBUS

    • OPC UA

    Alarm and warning states can also be managed via digital I/O, enabling immediate interaction with PLCs or supervisory systems.

  • Advanced monitoring functions include:

    • Configurable thresholds and limit values

    • Spectral masks for real-time anomaly recognition

    • Overall level monitoring on predefined frequency bands

    A dedicated Real-Time Synoptic displays:

    • Overall levels for all channels

    • Status of alarms and warnings

    • System and machine operating condition

    • Time-Domain Measurements

      • RMS

      • Peak-to-Peak

      • AC+DC

      • DC Level

      • Real-time filtering and integration

      Spectral Analysis

      • FFT with automatic DC component compensation

      • Overall calculation on user-defined frequency bands

      • Spectral mask comparison for anomaly detection

      Order Analysis

      • Order tracking with amplitude and phase

      • Tachometer-based phase reference

      • Synchro Mode for cases with indirect tachometer reference

      • Order trends over time (up to four orders)

      Acoustic Analysis

      • 1/3-octave analysis for microphone sensors

      Orbit Analysis (Eddy Current Sensors)

      • Orbit visualization (raw or order-based)

  • The post-processing module expands analysis capabilities with:

    • Polar plots for order analysis

    • Center Shaft Curve to evaluate shaft centerline shift

    • 3D Waterfall and Sonogram displays (Time/RPM or Frequency/Orders)

    • Full Spectrum analysis (Forward/Reverse components)

    • Calculation of bearing characteristic frequencies based on construction parameters and speed

  • The software provides two recording formats, both of which can be active simultaneously:

    1. Continuous Recording – BIN Format

    • High-frequency uninterrupted data logging

    • Ideal for detailed post-test analysis

    2. Interval Recording – LOG Format

    • Data stored at predefined time intervals

    • Ideal for long-duration monitoring (hours or days)

    Recording Trigger Modes

    • Manual activation by the operator

    • After a predefined time from acquisition start

    • Within a specific RPM range

    • When a parameter exceeds a configured threshold

  • A programmable reporting module allows the operator to:

    • Select metrics and analyses per channel

    • Generate layouts with one, two, or four graphs

    • Combine plots from different channels

    • Produce structured diagnostic reports automatically
