The cable with the NI 9237 Position sensor

Hello

I have a NI 9237 Half/Full-bridge analog input module. Recently, I acquired a position sensor led cable, which is essentially a potentiometer. You can find the schema from the link below or in the attachment.

http://www.celesco.com/_datasheets/SP2.PDF

I realized the NI 9237 requires a half-bridge or full-bridge circuit in the transducer, but apparently the potentiometer is not a bridge circuit, and when I connect the terminals output and excitement to the module, I am not able to measure voltage or resistance. Do you know some way I can use NI 9237 to measure the potentiometer?

Thank you!

Unfortunately, if your source is not designed for operation in a bridge circuit, you're probably not use the 9237 to take your measurements.  At this point, I would recommend a standard voltage input module.  I think you might find this worth reading.

  • How to connect the video cable with Qosmio G50

    Hello

    I bought the Qosmio G50-11s and received a video cable with it. (Jack mini jack RCA Red/white/yellow) But I find no way to connect it to my laptop, not the manual or all online resources talks about it. The problem is that I need to capture video from my VCR to my laptop and normal TV antenna comes with a lot of noise, so I have to use video in the cable. Any ideas?

    Thank you

    Hello

    In the past I made some experiences with it. I wanted to create DVD copy old VHS VCR equipment. Using the recorder even? I did this on Qosmio G30 but the principle is the same.

    The fact is that you need to send the signal to the laptop and to do this you must use the video port.
    I do not see that your Qosmio has several of them, so I think that the only way to send the signal to your laptop is to use the antenna port. What video output port you want to use on your recorder?

  • If the CSS layout Position is absolute and its content has been tested with the largest font in the browser with no. overlapping, then safe to USE?

    I found that if I used POTIONING RELATIVE to the CSS layouts and pasted my content in them, each of the displaced patterns.  So with the RELATIVE POSITIONING, I have re-aline formatting CSS with each new pasted content.

    In making the CSS absolute Position and tesing with the largest font in the browser, I did NOT meet the problem of duplication of text between two layout close to each other.

    Can there be additional problems with the help of absolute Positions?  Its looks to its worth the risk.

    see you soon

    If the page is good enough for you with the smallest size text as well as the largest text size, go for absolute positioning. It is certainly easier to place the divs with absolute positioning. The biggest problem with the AP div tags is the text problem you mentioned. I would like text in a few different browsers to make sure it looks ok to you.

  • How to set up breakpoints with a with a PCI-7344 linear position sensor

    Hello

    I'm trying to implement an algorithm of scanning for a piezo Nanonics 3D scene, who should synchronize with a card counting (PCI-6602) using breakpoints on the movement card (PCI-7344). The Nanonics Stadium has two position sensors (just for x - y) gives me a linear voltage variable according to the position. Nanonics connected these sensors for the two first entries analog motion motion card connector.

    Now I intend to use breakpoints to synchronize the digitization step to a card counting (probably using a RTSI cable), but I got the impression that this can be done by using the entries of each individual axis encoders, no do not using the analog inputs. Could someone comment on that? Explanations or advice would be greatly appreciated, thank you very much.

  • Send the command to laser sensor via a serial port RS232

    Hello

    I have a sensor of moving Laser of OPTEX FA Co., LTD. with a Communication Manual.pdf file attached. I modified the sample base series write and Read.vi of LV to send the command to the probe in order to receive a response. However, LV always returns an error on my VISA Write.

    In short, the structure of command for the sensor must have a form like this

    STX-command command-space-1 2 - ETX

    (more can be see the manual on page 3 or 18 of the .pdf file)

    where

    -STX: code showing the head of transmit data (02 H)

    -Command 1, 2: could be refers to table 1, 2 and 3 of the manual.

    -ETX: code illustrating the completion of data transmission (03H)

    For example, if I want to ask the sensor to send the data from A sensor head, the command must be

    STX-ABLE () A - ETX

    (20H) space is shown as ().

    I tried to send a string HEX (02 - 4 d 454153555245-20-41-03) for this command to the entry VISA, but all I get is ERROR.

    I enclose with this thread my vi and a printscreen of the ERROR.

    A lot a lot of appreciation for any help from any of you.

    I have my LV code can run successfully. He can read the COMMAND and return measurement data. The last time does not playback VISA because I used a cable RS232 to opportunity, and someone operated two pins (2 and 3) for another application.

  • How can I measure the output of a sensor pwm ultrasound using the module or 9403

    How can I measure the output of a sensor pwm ultrasound using the module or 9403

    Khalil,

    When you say 'measure' the PWM signal, exactly what to tell you?

    You're looking to measure the frequency or cycle of the signal function? You count the edges of the PWM output increase? Looking to control the waveform?

    With reconfigurable FPGA hardware, it is up to the user to define the function of the physical i/o on the FPGA chip. By connecting the signals as Adam suggests your digital pulse will be brought to the cRIO. In your FPGA program, you define the function. You can set a base counter or transfer digital data from single point to welcome you cRIO for floating-point more complex treatment. Example FPGA programs are located in the http://www.ni.com/IPnet.

    Hope this helps, please post any additional questions.

  • Return to the last code position

    When I am looking through a structure of great event or matter to study the LabVIEW code, it would be useful to be able just to go back to the last position within the code. (as in c# with "STRG +.") Even better would be to go back along the history of positions.

    This has actually already been proposed as an idea: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Create-anchors-and-shortcuts-inside-LabVIEW-code-for/i...

  • Help compare the negative and positive values

    Well guys, I do this example to show you what I mean

    With this example, I can get positive and negative numbers in digital

    But for me, the 'negative' mean nothing

    Example:

    If I have "100-200" for me the biggest value is - 200

    But if I compare the values of bouth got 100 as greater value

    I do the same calc for 3 different variables such as A, B, C

    and after that I need to calc whose value is 'more '.

    But my problem is that if I have the values "-350 300-400.

    the largest will be "300", but for me the 'negative' mean nothing

    so I need to the largest value is "-400".

    For all positive values, its works very well!

    I compare A and B, after the highest is on C and have a result!

    but when I have negative and positive values... I had this problem...

    and when I have negative values only I have a problem too.

    '-300-400-500' for me the largest value must be "-500" but labview-watch "300".

    as - 300 is greater than-500 in algebriac.

    And if I use absolute values, I will always have a positive value... but I need to know if the value is positive or negative

    No matter which, can help me with this?

    Thank you

  • The addition of IR sensors to sbRIO-9631.

    I have a sbRIO-9631 in the starter kit 1.0 and I try to connect the IR sensors to provide data more detailed than the sensors to ultrasound. My sentence connects to sensors. Any help is requested, I connected sensors to the Board, but I don't know if I did it correctly. If you know some tutorials that can help me, it would be greaty appreciated. the only tutorials I've found do far are what I use additional sensors for and not how to use them.

    Hello Defested,

    In the sbRIO-9631 operating instructions , that you can see on page 12, Figure 9, that the J7 connector allows you to access the analog I/o. This is where you do not use a C Series module. You can connect your sensor in several ways: CSR, NRSE and differential.

    You can see the article field wiring and considerations of noise for analog signals for more information on how to wire your sensor. We recommend to use a differential connection in case you have several sensors and are concerned about the loyalty of the signals. In the case where your sensor is a floating signal source, you would want to addition of polarization resistance of AI - AI GND.

  • SE raw tension of the NI 9237

    Hello

    I have a load cell connected to a NI 9237 module and she's excited to 10V. I would like to read the voltage of the load without the scale cell to get the output voltage.

    Thank you for your time

    Hi Robert.  The short answer is you can't.  The NI 9237 returns a value of ratiometric means that the data you get back is in mV/V, a unitless measure.  The unit performs the division in the material that allows for a more accurate reading because it uses the actual voltage in the calculation, but this scale cannot be disabled.

I know there is a ranking, but personally, I like to see how many posts a user has made and how ling, they were a part of the communities. There is valuable information in determining what someones credibility answer can be.
