NVGate 2022: Release note

NVGate 2022

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.)

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 to "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 higlight 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.

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

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.
