How to measure high voltage (60-70 v) and current (75-80 a) using a DAQ PCI or USB DAQ

• differential measurement high voltage

  Not sure if this is the best place, but here goes.

  We are trying to measure a voltage differential across a shunt in offset voltage, which is then further +/-10V over data acquisition cards measure. Here's a representative diagram of our circuit:

  

  We must also measure 24 of these shunts while we move the motor one way or the other. That in one case the offset voltage is near current of 12 volts (rank 9-16Vcc) that eliminates all the cards of the cDAQ and it looks like the PXI series too. We currently use one SCXI-1104 researcher but a USB port on a laptop for this measure. The SCXI-1104 has a voltage range of + / 60V and I was unable to find anything close to that in the product offerings of NOR. The reason why this is going to be a problem for us is that large corporation, we are forced to move to windows 7-64 bit and SCXI hardware are not supported for this operating system.

  I am open to any suggestions that others may have to help us fix this problem.

  Thank you

  We ended up finding some amplifiers that have been specifically designed for the high pressure shunts.  Do a search on digikey for amplifier of high-side current shunt and you should be able to find something.  These will turn the measure into a single measure is over voltage.

• Complete noob - would like to measure the voltage to manual start and stop

  Hello

  As the topic says I'm a complete noob when it comes to programming OR.

  I'm looking for someone to point me in the right direction

  Installation program:

  Windows8 office

  Visual Studio 2013

  NI 6255 PCI data acquisition card

  Block connection OR SCB-68

  What I want to do:

  I want to write a console application to measure the voltage on the signal ai16

  -I want to be able to start and stop the application manually

  -I want to be able to pressure measured in a CSV output.

  Where I am:

  I compiled and ran the example "NOR-DAQ\Examples\DAQmx ANSI C\Analog In\Measure voltage.

  It is said that I have "collected" samples but I don't know what that means, as I do not see an output file...

  What I don't understand:

  Samples - I do not understand cela or know even where to start

  How can output file - I get the file to save the collected data.

  Thanks in advance

  Hi Arron

  Thanks for the link, unfortunately, it has not helped because the instructions were for Visual Basic and C++ not. It was my fault for not putting the language of prog that I need help in my original post.

  However, I started to find help on this link: http://www.ni.com/tutorial/5409/en/

• Make a small change to an old project - how can I know which versions of drivers and RIO etc. has been used for the last good generation?

  If I want to make a small change to a legacy project for years before, I would limit my risk using the same exact versions of LabVIEW, etc. NOR-RIO.  So I check the project from the repo, but I do not know how to check what versions have been used when the last know good generation was carried out.  I don't want to introduce questions by recompiling mass to the latest version.

  What is advised in this case?  I could, before every posting of repo, take a screenshot of the tree of MAX software and save it in the project file.

  Any ideas?

  Rather than create a screenshot of MAX: MAX can create a report for you. You can take all the information expected of her.

• How can I read the active (connected) Renault and send then to the entry on DAQ device name help?

  I have a property system for daqmx node but it won't let me change it to read when I right click on it. I try to have my program detect the name of data acquisition which is plugged into the PC and then send to the daq assistant so that it runs properly wiithout having me manually change the name of the device every time I change hardware.

  You do the programming.  What is LabVIEW.  MAX gives you all the tools to do what you want and much more just to do what you want to program.

  Joined a VI that does what you want.  I look at all your devices and returns the first not simulated.  Apparently this list already excludes devices not connected to the system.

• How to measure how long a Boolean value is high with thick County?

  I acquire the impulse response of a parallax Distance sensor, but I I don't know how to measure the number of features that this signal is high (the time of the input signal is high is proportional to the distance). I would like to reset the counter thickness when this signal is low. is this possible? Y at - it another option?

  Thank you...

• How to activate the range high voltage E364Xa power adapter

  I use E364Xa power supplier code example downloaded with the driver E364Xa the Web site of NOR. I need the output in the range of high voltage voltage. Please see attachment tha. But the example code has been an error when the output voltage is greater than the range of low voltage. The default setting for the equipment is low voltage range. Does anyone know how to activate the range high voltage before you configure the output voltage?

  Problem solved. I found the order of output range VI.

• How to measure voltage every minute

  Hi all

  Currently, I'm new to labview and I'm taking steps of timed voltage.  Here's what I'm trying to do;

  I'm using labview 2010 and I am currently taking readings of temperature and moisture in sync with each other.  To measure the temperature, I'm using a cDaq mudule 9213, humiduty I am in using the voltage of the module 9234 and converting using the temperature and pressure of my moisture sensor.

  Now what I want to do is take the voltage and temperature say every minute or 30 seconds, but my buffer fills based on the readings of voltage and gives me an error or the table accepts the values of what im assuming is the buffer, one by one, rather than enter the data of the current module.

  My real question here is how to take measurements of voltage current every 30 seconds?

  Thanks for any advice.
