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
