Thermocoup​le DAQ USB 6008

Hello
I am novice of LABVIEW and DAQ system. If now i am going to use thermocouple, will it be suitable for me to use USB 6008 to acquire and analyze signal. USB 6008 has no filters inside. Using labview, will the noise be filtered out by LABVIEW itself using FILTER vi?
if signals are going to be analyzed continuously( it will measure ambient temperature with sudden hot air is blown against thermocouple intermittently), how would u recommend me? how can i take only signals with hot air and disregard the ambient temperature( as differentiate the hot air from ambient air).

Hi to all,
I don't understand very well whats mean this that says johnsold:
"The USB-6008 has 12 bit resolution (differential) and the most sensitive range is +/-1 V. This means that the resolution is about 0.5 mV."
could someone explain to me please?
I am trying to read sensor Lm 35, through the USB6008 and get a signal with noise near .005 V. In fact when I read any signal I have this noise level, can you advise me?
Thanks, greetings.

  • Will USB-6008 DAQ be able to power and record voltage for UMS T5 tensiometer at the same time?

    I would like to use my NI USB-6008 to provide power to my UMS T5 tensiometer  (http://www.ums-muc.de/en/products/tensiometer/t5.html) as well as take readings from it, but I don't know if this is possible to do properly. The supply voltage for the instrument can be as low as 5V, which I can easily get from the dedicated +5V channel. I am able to power the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, while reading the support literature for the instrument, I find the following:
    "Potential data acquisition pitfalls: Because the pressure transducer is configured in a Wheatstone full bridge, the input voltage and signal mV output cannot be connected to the same reference (ground). Hence, the signal mV output can only be measured using a differential voltage measurement. Therefore, do not attempt to make a single-ended measurement of the pressure transducer mV output."  (http://www.decagon.com/assets/Uploads/MeasuringUMSTensiometerswithnon-UMSControlandDataAcquisitionSystems.pdf)
    My understanding is that the 6008 can take a differential measurement if I attach the signal "+" and signal "-" to the positive and negative analog input terminals. However, it seems that all of the Ground ports on the 6008 are grounded to the same reference, which would make my voltage measurement invalid according to the paragraph above. So my real questions is: if I attempt to record the voltage using one of the analog inputs on the 6008 in this way, is the measurement valid? Or do I need to find a separate power supply with a different reference ground to ensure that the measurement is accurate?

    The specification sheet for that device is very poor. The manual is not much better. Companies which want to sell scientific equipment should publish decent data sheets or get out of business.
    In section 3.4.3 General requirements the device is described as a "non-amplified bridge circuit."  This information along with the bridge impedance should be in the specifications because it is essential to applying the device under any circumstances other than the nominal behavior at 10.6 V.
    The answer to your question is this:
    You can use it with the USB-6008.  The 5 V power supply will result in output voltages slightly less than half (5/10.6) the voltages specified under nominal conditions. You can use the differential input mode on the USB-6008.  The absolute input voltages will be about 2.5 V with the 5 V supply. That voltage is within the working range of the device. The differences will probably be less than 100 mV. The resolution of the USB-6008 on the +/-1 V range is about 0.5 mV so your pressure resolution will be around 1 % of full scale. The input impedance and termination voltage of the USB-6008 will introduce some errors.  These may be on the order of 5-10%. I cannot predict much better without the missing bridge impedance specification.  Those errors should be systematic and relatively constant. A calibration of the whole system - sensor and DAQ device together should allow you to compensate for much of that error.

  • Laser operation with a USB 6008 DAQ

    I'm wondering how I go about using the USB 6008 DAQ in conjuction with labView to turn on and off ths laser: 
    http://www.maplin.co.uk/p/1mw-3v-red-laser-module-le07h
    The laser must be turned on using 3V which isn't possible with this DAQ. I was thinking of usinga BC 109 transistor, then have the laser connected to an external power supply which is supplying 3V to the laser. then have the laser connected to the collector of the transistor.
    I set this up and it didn't exactly work out as the laser was drawing to high a current and not working correctly.
    Can anyone help me?

    OK. The problem is that you need to supply about 30 mA to the laser to get it to work. The digital outputs of the USB-9008 are limited to 8.5 mA or less. Furthermore, a laser diode is a current operated device. If you apply a fixed voltage the current will vary depending on the exact doping used when the device was manufactured and on it instantaneous temperature. The curretn rises exponentially with voltage as in any diode. The link you posted does not have any real data about the electrical characteristics of that diode.
    Typically a current regulating circuit is used to drive laser diodes.  The simplest circuit is a resistor in series with the diode connected to a power supply with a voltage higher than 3 V. The value of the resistor depends on the power supply voltage, the voltage drop across thes witching transistor, and how much current you want to run through the diode. If you have applied 12 V to that laser from a source which can provide substantial current (>50 mA), you have probably destroyed it.

  • Usb 6008 daq spi lcd server client

    Hi.
    I'm new to the labview.ich have a project and comes to data acquisition and remote monitoring
    detaille:
    2 computer are labview installed on both and connected to wifi / internet.
    the server computer connected with ni usb 6008 and it pt100 temperature sensor
    it should also include the measurement data display on an LCD
    it should be the client computer also read out the measured values
    has anyone an idea how could you start?., I will be very grateful

    This sounds like a pretty big task for someone new to LabVIEW.
    First get the DAQ working on the server PC.  There are tons of examples that ship with LabVIEW for taking DAQ, go to Help >> Find Examples.
    Getting the information to your other PC can be done many different ways, but maybe the easiest is to just use a Web Server to control the front panel.
    http://zone.ni.com/reference/en-XX/help/371361H-01/lvconcepts/viewing_fp_remote/
    Also you could remote into this PC using remote contol software and remote desktop.
    As for displaying data on an LCD.  A relativly simple solution is to use an Arduino UNO, the LIFA toolkit and an LCD connected to it.  It is a little bit if a round about solution but the LIFA toolkit comes with code to output to LCDs connected and it is relatively easy to use.

  • How can I make LabView 6.1to detect DAQ NI-USB 6008

    I have a LabView version 6.1, recently I bought a new DAQ model NI-USB 6008, I could not use it with my Labview version. Please, how can I adapt my DAQ for version 6.1 or update my LabView to detect my DAQ? Please advise me to a free applicable solutions. Thanks very much

    The USB 6008 requires DAQmx which requires LabVIEW 7.0 or greater. The upgrade to 7.x (or the just released 8.0) is not free. The only other solution I've heard of is to use the Call Library Function Node to make your own calls to the DAQmx dll. This would not be for the faint of heart or anyone wishing to come up with a quick solution.

  • NI-DAQ for USB-6008, LV 2012

    Hello, I have a NI USB-6008 for which I want to create a VI with Labview 2012 for logging one channel at 0-2V from a current shunt. In the our previous version of Labview 2011 I was experimenting with DAQ Assistant which made the job easy, but in LV 2012 this doesn't seem to exist.
    I was reading help files and I should be able to use NI-DAQmx but I can't seem to be able to find it. In NI Max I can see NI-DAQmx is there and can run  NI-DAQmx test panels on the USB-6008, but in LV 2012 I go to blank VI, block diagram, and I'm stuck. Any help will be greatly appreciated.

    Hi there,
    Can you check if you have DAQmx functions in Measurement I/O > NI-DAQmx in the function palette?
    If no, did you re-install the DAQmx device driver together with LabVIEW 2012?
    And what is your DAQmx version you're currently using?

  • Controling heating/cooling element with labview and usb 6008 DAQ card

    Greetings All
    I'm looking for a heating/cooling type of element that I can control with labview and my usb-6008 card. Heating/Cooling will just be for clean water and the temperture range will be from 0 C to 100 degree C.
    Thanks
    The heating and cooling elements can be seperate products. Any recommendations

    A simple kettle element will of course be sufficient for upto 100°C
    To get the temperature down you need a cooling system, what springs readily to mind of course is a refrigerator.
    Just a note of warning, water and electricity are dangerous bed fellows.
    On that note perhaps one of those vortex air units would be safer - they blow hot in one direction and cold in the other, nominally to 100°C

  • Error -10401 occurred at AI Group Config - in relation to USB-6008

    I'm attempting to run a simple vi that uses AI Aquire Waveforms.vi to input voltage data that I have coming in from the USB-6008 DAQ.  However, when I try running the program, I receive the error:
    Error -10401 occurred at AI Group Config
    Possible reason(s):
    NI-DAQ LV:  The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using the Measurement & Automation Explorer.
    And I'm not sure how to fix it.  In MAX, the device seems to be working properly and everyhting seems to work fine in the test panel, so I'm slightly at a loss.  I'm running Labview 7.1, and installed NI-DAQmx 7.5 which came with the USB-6008.

    Never mind.  I'm new to Labview, and didn't realize that I could not use the traditonal Data Aquisition components with the USB-5008 (I didn't even realize that NI-Daqmx was different).

  • Can I use more than one USB 6008 in the same program?

    I am working on a project that may require up to six USB-6008 modules.  Before I purchase more I need to know if I can use all six at a time in the same Lab View program.  Can anyone help?
    Solved!
    Go to Solution.

    Hello Nick,
    LabVIEW is able to handel that number of DAQ tasks quite easily, however you must remember that USB has a maximum bandwidth. Therefore you would have to ensure that you have enough USB hubs on your PC. Typically there are between two to four USB slots per hub and each of these will have a maximum throughput rate which will divided between all devices attached to that hub. Therefore although you may have four USB DAQ devices attached to four USB ports if they are on the same hub you may notice greatly reduced rates of data transfer. What I would suggest rather than purchasing six or more USB 6008, why not purchase one PCI card which is able to handel many more inputs with a larger bandwidth.

    What does it mean 'expected constant expression'? How can I get around this?
    What I want to do is pass the size of that data array from another function.

    Hi novaiscool,
    I think the issue is that you are declaring numsamps as a constant and the DAQmxReadAnalogF64 function wnats a non constant parameter.  Have you tried calling the function with a regular int or a value?  Give that a try and see if you get the same error. 
    You will also need to initialize numsamps to something since you are allocating an array using that variable. 
    Give those things a try and let me know how it works.
    Thank You,

  • Using USB-6008 on LIS331 Accelerome​ter

    Hi, I am looking to monitor my project with a LIS331 using the USB-6008 dac. Would this dac unit be acceptable with this accelerometer? 

    swong46,
    I would recommend using a USB 63xx series DAQ device. You might also be interested in the USB 8452, which is a dedicated I2C and SPI device. 
    I can also put you in touch with some of our sales engineers, who would be the most knowledable about your options. Shoot me a PM if you're interested, and I can give you a number to call.

    Solved!
    Go to Solution.

    Hi touheed,
    To be able to determine whether or not using a NI USB-6008 would be suitable for your application it would be useful to get a little more information about the measurements you want to take. If possible would you be able to provide the voltage range you intend to measure with your instruments, and the sampling rate you require? 
    Also I noticed in the subject line that you're going to be using an LVDT, will you also be generating the voltage for this with the 6008, or will this be done seperately?
    To give you some context, the NI USB-6008 does not take truly simultaneous readings at each instant, but will rapdily alternate between channels, giving effectively simultaneous samples. As this device has a sampling rate of 10 Ks/s, and you will be using 2 channels, the effective sampling rate for each input would be 5 Ks/s.
