How can I filter the noises of thermocouple using a TC-2095 and SCXI - 1102c?

Hi all

I currently have four TC - 2095 s connected to the SCXI - 1102c inside an SCXI-1001 chassis cards. These thermocouples are floating and I get a good amount of noise (400 Hz 3 phases and same 60 Hz noise) when we turn on some equipment such as fans, and fans. Using this current set up, how can I filter the noise? Or I would need to put in place a new hardware configuration (e.g., the SCXI-1102 cards)?

Hi RALoo,

The 1102 C has a lowpass filter with a cutoff at 10 kHz frequency, so you will not be able to filter into the material with your current configuration.

Your first option is to use a software filter.  LabVIEW has several functions that do this. More information can be found here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvanls/filter_vis/

The second option would be to change to SCXI 1102 cards as you suggest.  The low-pass filter of the 1102 was a cut-off adjustable to 2 Hz frequency, which will stop the noise of 400 and 60 Hz don't affect your readings.

  • How can I filter the noise of a signal?

    Hello

    I wonder if someone can point me in the right direction.

    I got the task to analyse the signal from a load cell, measuring vertical efforts on a buoy in the ocean waves. All I have are data files - Earth "calibration" run and a period of measurement of forces in the water. They are both simply traces time force vs. time. Calibration run consisted of hanging weight of the load cell. The problem is that the signal is very noisy, with a +/-10% fluctuation around the average. I don't see any particular model or the periodicity for the noise, but there may be something there.

    As a mechanical engineer, I don't know a lot about the signal processing, but I think there may be techniques to characterize the noise and filter it essentially leave the signal of interest (buoy in the water). I tried to run Fast Fourier Transforms of the calibration and signals live (in MS Excel), but they gave me a huge spread of frequency component, some with puzzlingy large amplitudes. Can anyone suggest alternative approaches or indicate where I have gone wrong?

    Thank you.

    What are the software tools you have at your disposal to achieve this? Using LabVIEW? What is the sampling frequency of your signal?

    The first thing to look for are the functions of filter and start by using a simple low pass filter (for example: Butterworth filter). In view of your signal, you expect the signal to be less than 1 Hz, so put 1 Hz as the crossover frequency. Who should get rid of a lot of noise already.

    How can I change the phone number to use Face Time?

    Your phone number come from your SIM, and when you open a session and activate FaceTime. It should appear automatically. If it is not, then I would say that your FaceTime does not complete the activation process. If you go to settings > FaceTime, you see something awaiting activation or waiting for activation under the switch to turn it on?

  • How can I get the tabs to go on a single line and a menu of Firefox?

    Firefox allows to have 2 lines above - Firefox menu with tabs and more and another line of the navigation toolbar. during the installation of some programs online, Firefox now have 3 lines at the top, with the Firefox menu on an entire line, the 2nd line of tabs and 3rd line of navigation toolbar. How can I get the tabs to go on a single line and a menu of Firefox?

    With the current versions of Firefox, you can choose to use the menu of Firefox (orange in windows; gray Linux) button at the left end of the Windows title bar or bar menus familiar as in earlier versions. The Firefox button is displayed by default only in Windows Vista and Windows 7, but you can turn on or off or switch between the two or temporarily show the menu bar when the Firefox button is displayed.

    If you chose to use the Firefox button and you use the default tabs on top, the tab bar will move to the title bar with the Firefox button only when you are to maximize window (the ' square' the middle button in the upper right corner of the Windows standard application window). Other selected toolbars will be displayed below that (bar Navigation, Bookmarks Toolbar and the toolbars you add via Add - ons).

    How can I copy the folder my documents in my iCloud drive and then I sync the two after that?

    You can simply drag in iCloud reader, but I pass and move documents in their files app instead. It will probably take a while to download all documents.

    It is not a way to sync without some third party software that synchronizes folders, or learn how to use rsync in the Terminal.

    Instead of synchronization, simply use the iCloud drive in the 'Documents' folder after you move the files.

  • Gmail button (in internet explorer) keeps having moved to the right in my taskbar when I wasn't staying on the left (that's why I first open). How can I get the taskbar buttons to stop randomly to reorganize and stay in order?

    Gmail button (in internet explorer) keeps having moved to the right in my taskbar when I want to keep it on the left (that's why I first open).  How can I get the taskbar buttons to stop randomly to reorganize and stay in order?  I'm talking about the buttons on list of my open applications and documents in Windows Vista.  The bar tasks are "locked", but the button of the window open with gmail in internet explore reappears suddenly in the good moments apparently random.

    It is in the middle part of the taskbar (what I found online so far is on the start menu, the quick launch area or area/system tray of notification, the location of the taskbar in full, either about grouping taskbar - I disabled because I would like to separate).  Can anyone help?  I don't understand why this is happening (or why microsoft would never do).

    Lock the taskbar that it prevents to be moved elsewhere on the office and maintains the different sections where they are - it does not block the tabs showing what is open where they were when they were opened.  There is no control for this function.  Maybe if you uncheck similar taskbar buttons group it will help, but I honestly don't know (and fear he won't make any difference - it may even make things worse).  This also happens to me and I was unable to find an answer.  I think that there are more than just random, but I can't telll you why he moves the legs periodically (sometimes it works fine all day and other days it happens almost immediately).  But still, there is no control for this function, so there is no way to tell him to keep a specific order or to lock an established order, once it has been created.  I suspect that it happens because the notification area icons appear and hide and new programs open and close and which changes the amount of space available and so he rearranges things so that they match and apparently does not always consider the original sequence in which the elements have been added.  Maybe if you remove the Quick Launch toolbar and then add again, the order will reset (but that I know not - probably not in the original sequence, which I doubt is logged nowhere - it did not work when I tried it).

    Unfortunately, I don't have a solution to this problem (and I spend a little time looking for even before myselff posed the question) and do not believe that there is a.  It is also unfortunate that you can't move them so they can be put back in the right order if they change.  I don't think that there is nothing wrong with your system or that it is something that can be repaired or fixed - it's just the way it is and we just have to live with it.  I don't know any 3rd party software that controls the order of tabs open in the taskbar program (but you can check out Bing, Gooogle,www.tucows.comand www.download.com to see if I'm wrong on this - here n "t all when I looked trying to solve this problem for my own system).

    I'm sorry it wasn't what you wanted to hear, but it's like that.  I don't know if it's different in Windows 7.

    Good luck!

    Taskbar will appear to take with you when you either come from anywhere near the bottom of your screen or a security alert is displayed.

  • I forgot my password for windows 7 for my laptop and a reset disk has not been created. How can I recover the password or create a new one? and I have a dell desktop inspiron one 19

    I forgot my password for windows 7 for my laptop and a reset disk has not been created. How can I recover the password or create a new one? and I have a dell inspiron one 19 desktop... your help will be very appreciated thanks in advance!

    Here are the usual methods to solve this problem:

    • Restart the computer with your Windows repair CD, then use system restore to set Windows in a few days (only works if you have recently changed the password).
    • Logging in as a different admin account and then reset the password for your existing account (works only if create you an alternative admin account).
    • Log in as administrator mode without failure, then reset the password for your existing account (works only if you have activated the account administrator and know its password).
    • Insert your flash drive USB with the password key file (only works if you have created such a keyfile).
    • Check your paper files (works only if you threw down the password somewhere)

    If none of these standard precautions work for you, then the remedy will be painful. Post again if this is the case.
