temperature sensor with the acquisition of data usb-6009

Greeting

I want to use a sensor with usb-6009 to save the variation of body temperature about 15 minutes and then use these data in labview.

If you please you can advise me with the best low-cost use and the way/circuit sensor connect it to the usb-6009.

Hi ba7soun,

If you can use with USB-6009 LM35 depends on the range of output voltage of the sensor. I understand that it requires a 5V supply with respect to the ground, which you can provide to the USB-6009 (more than 200 my should not come from the USB-6009).

The maximum range of the USB-6009 is - 10V to + 10V, while the minimum range is - 1V to + 1V, also probably the output signal of the LM35 will be in this range. What you need to do is to compare the full range of the output signal with the range of the DAQ divided by 2exp (14) (because it is a 14 bit ADC) and ensure that the first is much more than the latter.

Kind regards

Condette Dhruv.

  • Sensor with Signal conditioner for the acquisition of data NI 6009 force

    Hello

    I currently lead a unique test by using a pendulum. Currently, there is a rotary potentiometer measures the rotation of the shaft and a force sensor to measure the impact. The Rotary potentiometer and data acquisition work like a charm in SignalExpress but I currently have problems with the force sensor.

    The installation program:

    Sensor Signal conditioner box-->--> DAQ (analog input 1 & corresponding to the ground) by force.

    In Signal Express, when I "Add Step" process - should I choose "Acquire signals--> DAQmx Acquire--> analog input--> [voltage? The force? Custom?]

    Thank you 1 million,

    AW (big noob)

    Hi a_wishart,

    I don't think that the evaluation of Signal Express version is the reason for which you get this error, see the related document, there are several possible causes of this error.

  • Simultaneous to the AO and HAVE with the acquisition of data NOR USB 6001/MATLAB Toolbox

    I am very new to data acquisition and bought a NI USB 6001 to start to learn. Because I can get free MATLAB through my University, I use Matlab data acquisition Toolkit as the data acquisition software.

    My problem is that I get the following error message when I try to generate an AO (an LED voltage) signal and measure a signal I (voltage of a battery of 9V) simultaneously.

    ATTENTION: This change is caused in the dump output data queue.  Use queueOutputData for the queue data before the start of the object.
    Hardware does not support the specified connection. Check the user manual of the device for the valid device routes and pinout.

    However to measure IA or by generating the AO each by themselves works perfectly well.

    My Matlab script looks like this:

    daq.getDevices;

    s = DAQ.createSession ('or');

    s.Rate = 1000;

    s.DurationInSeconds = 10;

    addAnalogInputChannel (s, 'Dev1', 'ai0', 'Voltage');

    addAnalogOutputChannel (s, 'Dev1', 'ao0', 'Voltage');

    aoVoltage = 1.8 + 0.1 * sin (linspace (0, 2 * pi, 10000))';

    queueOutputData (s, aoVoltage);

    s

    startBackground (s);

    Note that adding the channels HAVE and AO at the session also works, however I get the error mentioned at the start of the session. This is a limitation of my data acquisition hardware (I don't see something like that mentioned in the manual) or do I have to modify the script?

    The pins connected for the LED are AO0 (+) and AO GND (-).

    The pins connected to the battery are AI0 (+) and (-) AI4. (The problem is still there if I use the reference to the ground for AI)

    6001 cannot make simultaneous tasks.  Very standard limitation of the low-end hardware... just don't have on board computing resources to handle such things.  Even the 621 x boards have only limited multitasking abilities.

    Can intensify to a high range data acquisition ($$$) or buy a 2nd a low end and synchronize tasks in software (not as precise calendar).  I've done two approaches, one is "best" really depends on demand... If low-cost or high-performance is a priority.

  • Problem with the acquisition of data on XP Embedded

    Hello

    I'm using LabView 8.5, 8.7 DAQmx. My application is collection of data of NI USB-6009 14bits. I tried to create applications for tablet PC with installed Windows Xp Embedded. I created the installer on tablet with installed Windows 2000.  I solved all the problems that occurs during installation. First version of the program have assistant DAQ in a main VI who collect and process the data. It worked properly on Xp Embedded. Second version was split into two of the Subvi. One is data collection and secondary processing. Each VI have own while loop. Both Subvi is placed in the large loop and they start at the same time. I am writing all the data to global variables. On PC with the windows application created 2000 worked properly. Error occurs when I moved it to Xp embedded. VI, which is the collection of data, the error see the 200361 code and text:

    DAQmx reading (analog 1-d Wfm NChan NSamp) .vi:2
    The task name: _unnamedTask<0>

    I know its something with the sampling and the clock, but I do not see where is the problem. In the main loop and two Subvi I 'wait until the next ms Multiple"block with a value of 200. DAQ Assistant were set as follows:

    Price: 1000

    Number of samples: 1000

    Timeout (s): 10

    Can you tell which can cause this error?

    If you would like more information please write here.

    Problem solved. There was connection between PC and USB-6009. Program works when I connect the USB-6009 housing directly to the PC. Previous connection was through usb hub.

    Thanks anyway.

  • About precision of analog input of acquisition of data USB-6009

    Hello

    I have a problem where I'm reading a temperature signal (10mV / ° c) using the USB-6009 case, but a problem of accuracy of the input signal of the DAQ hardware.  The temperature at room temperature reads at a constant 230mV (23degC) using a multimeter device, but with the DAQ hardware, I see the signal bouncing around to 25mV, + effects greatly my work.

    I was hoping someone might have a solution to this as my brief search forums nothing have mounted.  Is there a way to average this broad band to the extent of the input signal or from resovle anyway?

  • Sampling frequency for two different routes for acquisition of data USB-6009

    Hello

    -Anthony

    All tasks on a DAQ card using the sample clock should use the same clock.  Therefore, you cannot have two tasks on the same sample of DAQ card at different rates.

    Alternatives would be:

    1. to combine all channels in a single task and to accept additional data

    2 get an additional DAQ card to use at the same time

    Hello

    I installed the NOR-DAQmx driver to operate the USB-6009 module.

    The device is well recognized by NOR-DAQmx devices basis as well as by MAX V3.1 as Dev1.

    Yet, impossible to create a virtual channel with MAX, and cannot create a task with NOR-DAQmx Base Task Configuration Utility: Dev1 does not appear in the device drop-down list.

    The Green LED on the USB-6009 en permanence module flashes.

    What do I do? Did I miss something selected in the installation, already redone 3 times on different PC running XP Pro SP3

  • Combining the scalar output with the acquisition of data time vs RPM

    I have no idea why my 9402 NOR does not work as it should, but I don't know he counts the pulses, and at that time I need data for my forthcoming report.

    I came to a .vi that contains a very basic way of relating counties in time, however, I need to save the data to an excel sheet for I can analyze it. I have a motor which is connected to an assembly. My encoder measures the rotation of the shaft (no measure of direction availible) which is directly activated by the engine. As load us the assembly, I want to see what the speed of the motor through the encoder. So let's set the engine speed (anywhere from 1 to 100 rpm) and then load the assembly and see if the engine cannot maintain speed. Seems simple but my module is having a difficult time getting one any frequency of the encoder.

    Anyway, the .vi I use counts the pulses and divide them by 100 ms once every 100ms. This generates a scalar value that I want to record with regard to the overall time, prefferably every 10th of a second (100ms). I know that I combine the values in a table (2 columns, an indefinite quantity of lines). How can I combine two elements ([time, RPM]) in a table every 100ms and having the table keep expansion of the lines until I hit stop?

  • measurement of voltage battery pinout 1.5 V AAA DC with acquisition of data USB-6009

    Hello, I have a very basic question with pinout when measuring 1.5 V voltage on a USB DAQ 6009, using an AAA battery. Is it okay to connect (+) to AI0 and (-) to such AI4 suggested in MAX?

    Nothing else required?

    (attached pinout)

    Thank you

    Hi feanorou,

    Yes, you have the Terminal configuration as award-winning, then using the 0 pine as AI (GOT 0 +) and using PIN 4 HAVE (I - 0) is a good setup for measuring the AAA battery.

  • Generation and acquisition at the same time, acquisition of data USB-6356

    Hello

    I have a VI how is able to read entries with a USB DAQ-6356 and I use a generator of signals 'Agilent 33522 A '. I want to generate and acquire with the acquisition of data.

    In fact it works but not well, the frequency is not very stable and does not stop the 2nd loop with 1 (2nd is generating, 1 is Acquire).

    Thanks in advance

    P.S my VI isn't a state machine true because I need to fight against it at the moment.

    OK, so you're at 3 ms/s in writing and reading at 1.25Ms / sec and you wonder why he has a little difference in the frequency set?  Ideally, you want to read and write to share a sample clock but by selecting at least the same frequency clock (or one that is one multiple of the other) would go a long way to fixing this source of your error.

    The second source of error: you generate a contineous waveform.  unless you select 'whole number of cycles' there is a discontinuity when the end is reached at an arbitrary phase and the phase is reset to zero at the beginning of the wave.  DAQ assistant writing can "Use Waveform Timing" to adapt its sync settings to the dt waveform and the number of samples.

  • Need a new acquisition of data USB multifunction device

    Hello

    Currently I use a PCIe - 6321 Multifunction DAQ hardware to control my stepper motor. I need to change the PCIe - 6321 and use the engine with a device for the acquisition of data USB multifunction bit PCIe - 6321. I'm not sure which USB model to select. Can I please get help about the choice of the right MIO USB data acquisition device that works similar to the PCIe - 6321.

    Thank you

    Bharath J S

    The 6212 differs from the 6321 somewhat on the digital side, which probably you use to control your stepper motor.  For example, it was only software DIO timed tasks and has only 2 counters with a set of features (e.g. no output meter in the buffer).

  • When I send a 5v of data acquisition, the voltmeter indicates 5V, but when I connect a "normally open" valve Parker for the acquisition of data, the voltage decreases automatically a.14 V. It seems to be grounded. Why is this happening?

    We send 5v data acquisition using a voltage generator. Hook us it up to a voltmeter and see 5V. When connect us the generator voltage to a valve "normally open" parker, the voltmeter indicates .14V. It seems that when we connect the two sons of the valve for the voltage generator, the son act as pattern. We want to control the voltage flowing to tap through Labview. We checked the wires to the valve and they work very well, because if we send a constant 5V since the acquisition of data and put ashore, she, the voltmeter indicates 5V. Someone knows why the son act as pattern and low blood to .14V?

    nsatpute wrote:

    Our data acquisition is NI USB-6259. The valve requires only a 5V max and our DAQ provides up to 5V. However, after connecting the valve to the acquisition of data, the grave tension to almost 0. We start from the principle that the son somehow act as the reason, but we are not sure if this is the case.

    The question here is not how much voltage the valve wants, it's the current needs of the valve.  The 6259 can put only 5mA via an analog output.  Your very likely tap needs much more than that.  If you need to add in an amplifier circuit that can supply more current to operate your faucet.

    It is not a robust application, but the box will be moved and I don't want it put in the open air. I simply put a velcro pad on the back and the atttaching in this way. Should be all I need.
