NVGate 2022: Release note
Ergonomics
The interface gathers the analyzers functionalities in simple, clear and easy to identify tabs organized according to the main operations (home,acquisition , analysis, data , display, report, automation, preference.)
Tab: new icone disposition
Key features have been emphasized by interface, guiding the users to the best way using their OROS 3-Series analyzer. The software entries are organized in a logical operations way. There are 8 different tabs corresponding to the main operations type:
Home
The goal of the tab home, is to make a user friendly tab for doing a measurement.
You can load a project , create a project (thanks "go to results"), start acquisition, see your data, the disk space and see the user.
In fact for a lot of every day application you can stay on this tab, no need to check the other one.
we have also highlight the function called attachement 
on this tab
Attachment: Enables to quickly identify if files (reports, pictures, videos....) are attached to the current project. Note: if the "Default project" is active, the Attachment button is greyed.
|
|
The Attachment folder of the current project is empty or does not exist. |
|
File(s) are located in the Attachment folder of the current project. |
Acquisition
This tab provides all the necessary entries to setup the front-end and the use of any channels in details. It separates the acquisition channels setup from the outputs, triggering, tachometer, and filters ones.
Analysis
In this tab, the software gathers the dront end , recorder and analyses controls. Each icons corresponds to a plug-in analyzer. The content of this tab depends on the purchased optional plug-in.
data
This tab provide function to deal all your data, transfers Projects, Measurements, Models , export and import your data, filter the project manager.
Display
This tab covers the results display control. It allows creating, fulfilling, arranging and viewing the windows and layouts. It controls the scale, units, weighting and data operations of any graphs, manages the waterfalls and extraction graphs and the markers.
The display tab have been entirely think and improve with NVGate 2022. Some function have been higliths : freeze , zoom , add layout. We have also improve the mode: cursor, marker, zoom, moove, rotate. This mode can now be selected in One click. Also now the marker mode will be always in default mode, so if you unselect a mode it will go back directly to cusor.
preference
These tab provide direct access to the user’s definition, user's preferences and sensor database.
Automation
The tool tab contains powerful and helpful tools to automate repetitive tasks made with the analyzers.
Go to results: new one click icones
New "one click" function have been add on the go to results for more user friendliness.
view recording: will open the signal monitoring window on top of the current layout. In the case of this window is already open in another layout, it swaps to this layout.
Add Layout: Creates a new layout. A dialog box used to name the new layout is displayed by clicking on the button. A new tab is created and selected, corresponding to the new layout.
Opens the waterfall triggering dialog. This dialog allows selecting the trigger of by the waterfall plug-in. (only availabale on profile and waterfall tab)
RPM buttons create automatic events
The Rpm button have now beeing entierly redesign. Aply this button will automaticall put the waterfall trigger on delta RPM or periodic.
This will make the setup of NVGate much more easier for a rotating or run up apllicaton. (only available on profile or waterfall tab)
In details this button will :
- Create a Delta RPM event, source = the one activated in the "Tach.". Delta velocity : 10 RPM.
- Create a Periodic event (0.5 sec)
- Create a Combined event 1. mode: "Delta RPM OR Periodic 1"
- Set waterfall Trigger to Combined event
- Create of an RPM event (source = the one activated in the tach field)
New settings by default
The settings by default in NVGate have been update to the one below. With this default seetings, you can do rotating analysis measurement directly.. Be aware than if you load an exiting project , this is NOT affected you previous settings are keep. You can also easily change this settings.
FFT Overlap: 66%
FFT lines: 3200
FFT Overall low freq : 2 Hz
SOA resolution: 1/8
SOA overlap: 5
SOA OVL lower order: 0.2
Event Delta RPM: Delta velocity 10 rpm
Waterfall Depth: 1000
Tachometer/RPM Profiles/ duration: 120 sec
New units available
Angular velocity: Hertz
Pressure: Pascal and Bar
Torsionnal velocity: RPM
NVGate reader mode
Use NVGate in reader mode : no need usb dongle or hardware.
Fractionnal tach : ration over 100
: Fractional tachometer: computes RPM speed for a non accessible shaft by using gear ratio setting. Adapted for gear boxes and transmissions. The ration ca be now set up to 100 ! (previously it was 2)
Used to define up to 4 fractional tachs using data from the tach or the Ext Tach.
- Tach ratio: this is the ratio between the output angular speed and the input angular speed. This setting is defined by the product of 2 fractions: N1/D1 * N2/D2 where N1, D1, N2 and D2 are integer values. Tach.1 / Tach.2 ratio maximum value can be set up to 100.
Up to 3 real time: plug in SOA
Oros , leader on rotating vibration analysis, is the only one in the world to let you do at the smae time: 3 real time synchronous order analysis (this is also available in post analysis.)
Add on : PV (pressure volume) diagram
How to use :
- Define one (or more) channel as a pressure.
- Add this channel into Sync. order (SOA) plug in.
- On SOA plug in , average, domain, select: "Angular"
- Open PV_Diagram.exe
- Click on refresh (right click) in available results if you do not see anything.
- Select the input.
- Compute once will display the PV diagram base once based the last triggerd block.
- "background computation, will continuously compute the diagram.
NVDrive : Read Write NVGate properties (Project / Measurement)
Thnaks to the python toolkit, NVDrive allow you to take control of the analyzer with command line. New NVdrive command have been added on the NVDrive toolkit to read , write and delete the NVGate properties. This can apply, on project measurement and Signal.
