simple pressure transducer


Does anyone have a pressure transducer with offset null simple vi constructed in code. I'm relatively new to labview and most of the examples I have seen are way to complex for me to understand what is happening.  Is it better to use the DAQmx Wizard or data acquisition?  I have two sensor of pressure (excitation omegadyne-10V) hung on to with a module for 1121 SCXI-1327. I wrote a program to convert mV to pressure using a linear scale, but that's all I know how to do at this point! And I want to know how to read the two transducers.  Thank you!

Don't forget that you will need to change your excitement of inside out and remove the part with the shunt calibration.

    The NI 9237 module is installed in a chassis OR compact 9174 DAQ.

    I shall be measure the pressures of air brakes truck to compressed air system of zero kPa (gauge pressure) up to allowance of 1000 kPa (gauge pressure).

    The 2 wires on the transducer are identified as: food + and + signal

    I would appreciate it please advice on the appropriate terminals on the NI 9949 RJ - 50

    Unfortunately, it seems that you have the wrong module for this task.  The 9237 is used to measure the production of bridge-based sensors (for example, a strain gauge).  Signals that it is supposed to measure are fundamentally different from the 4-20mA signal pressure transducer outings.

    Take a look at the NI 9203, 9207 or 9208.  All have at least a few channels designed to take a current 4-20mA input.  Then, give the team nor a (877-387-0015) call to talk through your application and make sure that you select the right equipment for what you want to do.

  • How the pressure transducer Validyne system-> Validyne CD280-Dual-> SCB - 68-> PCI-6024E-> LABVIEW works and how we can calibrate the pressure sensor?


    I am completely new to LABVIEW software.

    I learn a LABVIEW code existing my pressure (attached) acquisition system which has the path of data as follows: pressure transducer Validyne--> Validyne CD280 - Dual--> SCB - 68--> PCI - 6024E--> LABVIEW and I have a few question:

    1. How does the complete system of the transducer to the LABVIEW work? That is, if we apply the pressure of the transducer, it will change the resistance of the probe then...?

    2. How can I find the equation that expresses the relationship between the pressure and the tension to the keys of the Validyne double-CD280 in the LABVIEW?

    3. If I want to do the probe calibration, what are steps?

  • 6008 NI DAQ issues of reading pressure transducer

    Hello everyone, I am a new user of labeled and not one expert on electronics, so please bear with me.

    I'm trying to read a signal 4-20 my by a pressure transducer using a NI DAQ 6008 and Labview version 8.6. I am running Windows XP Professional. I'm the transducer, ( providing a voltage of 10 v I have a 235 external resistance ohms between the terminals positive and negative data acquisition (although I am not sure that it is correct). At the start of my VI, I am able to measure a voltage of environ.9 data acquisition (verified by a voltmeter/ammeter) V and a current of environ.39 my.

    My problem is the fact that when I have a supply pressure of my sensor, I have not received any signal whatsoever by the transducer, despite the fact that it is important that the pressure should give me a signal. Is this a problem with my installation, connections, data acquisition (which has been reset in MAX number of times and pass the self-test) or the sensor itself?

    Thank you for your time and consideration

    Hi prenerk,

    You are right that resistance must be connected to the terminals positive and negative a way to HAVE to create a measured voltage to current.  Here are two troubleshooting steps you can try:

    1. check with an ammeter so you are detecting a change in the current when you apply pressure to the transducer.

    2. open the Explorer Measurement & Automation and use a Test Panel to measure the voltage of the device.  This will ensure that there is a mistake in your LabVIEW code.  Also check the MAX pinout diagram to see if your sons are correctly plugged into the channel of GOT it.

    If you have not discovered a problem with the above steps, we will have to learn more about your sensor pressure and how you connect it to the 6008.  We will need the information on the sons of the Omega instrument and how they are connected to the excitation voltage source and 6008.  Let us know how it goes!


  • Pressure transducer

    I received an omega pressure sensor (model px309) with only three wires: Red (power supply +); Black (power supply)-; and white for the signal.

    Should the output voltages of 0 to 5 and a voltage range from 9 to 30. It measures gage pressure.

    I use a power supply that can output 12v to provide power to transduce and a Ni-9205 to collect the signal.

    Red and black were connected to the power supply. The white one was hooked up to the ACH0 to collect the signal. In the test diifferential model, I used a wire to coneect to COM. ACH8 Also, I plugged the black wire pressure transduce to COM.

    Is this the right settings?

    I run my program and I found that the signal is not continuous, and it has a Variant. Please see attached picture.

    Is this normal?

    Hi Kang,

    Depending on what beach you go the DAQmx task for the 9205, looks like expected behavior.

    It seems that noise you see is on .1mV, which is quite close the specification of random noise for the NI 9205 module:

    If you select a range of 0-5 v for example, DAQmx will put the module mode +-5V, which corresponds to a 116 uVrms noise, that seems pretty close to what you see.

  • How to get mydaq recognize px309 pressure transducer % 3F

    It has only 3 wires instead of the usual 4. They are black, red and white and negative excitement, positive excitement and signal respectively. I plugged the black wires and red to an external power supply, the white wire to the myDAQ HAVE. Then I went to labview, opened DQA assisntant - acquisition - tension - ai1. Then I put samples of continuous get ot and drew a graphical indicator and press the run button. Yet, the only signal I get is noise and graph (amplitude time vs) shows no change when pressure is applied.

    Have you tried also runs the black wire from the transducer into one of the analog grounds on your MyDAQ? Measures data acquisition potential, without reference to ground the unit will not be able to measure anything.

    You can also use an output on the analog MyDAQ to produce the voltage instead of using an external power supply.

    I hope this helps.


  • How to wire NI 9203 to Emerson PT5 pressure transducer

    Hi all

    I started studying with 9188 OR cDAQ and analog input NI 9203 module. I'm really new on the DAQ hardware and I confused about my wiring for the NI 9203 pressure sensors. I want to use 6 pressure transducers whose output signals are ampere (4-20 my). In the manual operation of NI9203 shows that there is only 1 negative port (COM). Could I wire 1 more NI 9203 pressure sensors? If it is possible, how would I do that? The pressure transducers that I wanted to use a 2-wire and its technical specifications is Emerson PT5.


    You should be able to branch out of the output of the power supply 24 VDC 8 drivers. Does that help?


  • Pressure transducer USB-6211 noise error

    Hi all

    I tried to connect a pressure sensor through my data acquisition by the voltage reading and when you use a multimeter to check the voltage measured by the son, I get exactly what I want, but when I look at reading through labview, I make so much noise that I can not even acquire a strong enough reading for the tests. When to play with filters and blocks measure, I'm sure that some of the ways to reduce the noise and get the reading of the amplitude of crete would, just do not know where to go next, as I have tried so many options like this already.

    Problem has been resolved. Simply a problem of ground that I threw.

  • Problem with the sensor of pressure and NI 9205 with NI 9263

    I have a bridge pressure sensor based with a range of 0 - 5000 psi and requires a 10 V excitation. The output is 3 mV/V. I plugged on a cDAQ with a NI 9263 providing excitement V 10 and a NI 9205 to read the output values. I would expect a 0-30 mV output corresponding to 0 - 5000 psi, correct? (Incidentally, the NI 9205 module must be accurate to 0,1 mV or this should lead to a precision of about 16 psi, right?).

    However, when I tested it in fact the sensor on the run a test ranging from 0 to 1000 and back to 0 lb/po2 (now for quite awhile to States of pressure) the values I get from the NI 9205 are about 204.614 mV for 0 lb/po2 and then goes 204.867 mV to 1000 lb/po2 (actual results are noisy (, so these are averages). I enclose the SignalExpress file used for the test as well as the Excel file containing the resutls. Testing was performed with a number of other active sensors (load and displacement, LVDT and gagues strain gauges) in addition to the pressure that I'll eventually use them for my experience. In the SignalExpress file, the pressure transducer is the only sensor receives the excitement of the NI 9263 (ao_0) and ai_3 on the NI 9205 module.

    So this time I tried to run the test again, but changed the SignalExpress file (second .seproj attached) to include only the pressure transducer. But now I don't have an answer at all by the transducer (it remained simply flat).

    As to the connection of the transducer material, it is a connection 4-wire (excitement, - Exciation + Signal - Signal). I plugged the cables from signal to pins 4 and 23 (AI3 and AI11) for a differential pair. Then, I plugged the son of excitement to the pins 0 and 1 (AO0 and COM). Finally, I took a wire jumper and connected 23 on the NI 9205 module PIN to pin 1 on the NI 9263. I made this last step at the suggestion of support OR for a previous problem with a string potentiometer. This stage connected the ground between the two modules (the sensor did not answer with a pressure change when I don't have the wire).

    I appreciate any help as to why. I did not receive a 0-30 exit mV.

    his does not work like that.

    The probe should @30mA to 10VDC.  There is only available from the canal AO 9263 1mA.  you need another power supply.

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

    I would use my NI USB-6008 to power my blood pressure monitor UMS T5 ( but also to take readings of it, but I don't know if it's possible to do it properly. The power supply for the instrument can be as low as 5V, I can easily get the dedicated + 5V channel. I'm able to feed the instrument and connect it to an analog input on the 6008 and measure a voltage in differential mode. However, when you read the documentation of support for the instrument, I find the following:

    "Potential pitfalls of data acquisition: the pressure transducer is configured in a full Wheatstone bridge, the input voltage and mV signal output can be connected to the same reference (mass)." Therefore, the mV output signal can be measured using a differential voltage measurement. Therefore, do not make an asymmetric measure of pressure transducer mV output. "(

    My understanding is that the 6008 can take a differential measure if I attach the signal '+' and the signal "-" to the analog inputs of positive and negative terminals. However, it seems that all the ports of ground on the 6008 are grounded to the same reference, which would make my measure of invalid tension according to the above paragraph. So my real question is: if I try to record the voltage with one of the analog inputs on the 6008 in this way, is the valid measurement? Or I need to find a separate power supply, with a different reference field to ensure that the measure is accurate?

    The technical details of this device is very poor. The manual is not much better. Companies that want to sell scientific equipment should publish decent cards or get out of business.

    In section 3.4.3 General requirements the device is described as a "bridge not amplified circuit.  This information along with the impedance of the bridge should be in the specifications, because it is essential to apply the device under any circumstances other than the nominal behavior in 10.6 V.

    The answer to your question is:

    You can use it with the box USB-6008.  The 5 V supply will result in output voltages a little less than half (5/10.6) the voltage specified in nominal conditions. You can use the differential input mode on the box USB-6008.  The absolute input voltages will be approximately 2.5 V with the 5 V power supply. This voltage is in the range of the aircraft. The differences are likely to be less than 100 mV. The resolution of the USB-6008 on the + /-1 V is located about 0.5 mV so your resolution of pressure will be about 1% of full scale. The voltage input impedance and termination of the USB-6008 will present a few errors.  These can be in the order of 5 to 10%. I can't predict much better without the missing bridge impedance specification.  These errors should be relatively constant and systematic. A calibration of the whole system - sensor and together hardware DAQ should allow you to compensate for a large part of this error.


  • I can't Omega PX4200 pressure transducers where I can get a reading of Labview


    I am a new user of LabVIEW, and I currently try to wire in a 4-20mA Omega PX4200 pressure sensor in an NI USB-6009 Data Acquisition device. I have sources of power like a P SOLA SDN 5-24-100, and I use a 3-wire system. I have the black wire going to SOLA a +, the ground wire to the GND on the NI USB-6009 case and the white wire going to the AI0. Currently, I am unable to generate a significant signal either in solution of measurement and Automation Explorer or LABVIEW Signal Express 2010.

    If anyone has an idea on what I'm doing wrong, just reply to this topic.

    Thank you


    The USB-6009 measure the voltage.  The pressure transducer is a current signal.  You must add a kind of conditioning of signals.  At a minimum, you must use a resistor to the terminals so that you can convert the signal 4-20 mA, the transducer is a tension.  To convert a signal of 20 MA in 10V, you would need a 500 Ohm resistor.

  • Departure of analog playback corrupts waveform analog writing

    I came across a strange illness that can happen if I run a diagnostic routine on my system.  My routine of diagnosis is essentially four while loops, each containing code to control specific items in the hardware of the system. Two of the articles are DIO and worked still no problem.

    (Am under LV 2013 on Win 7 with an acquisition of data PCI-6014)

    The other contains a similar read using AI8 and the last analog writing on AO0.

    When I run the analog writing task, I am animals in a waveform that essentially pwm output.  In itself, this works very well.  The only parameter that I change for waveform generation is the total time in seconds.  I put in two seconds and I get the result adjusted for 2 seconds.

    The problem occurs when I try to do that and read the analog input (a simple voltage to a pressure transducer) at the same time.

    If I begin the task of reading during the writing task execution, modulation goes high signal and the rest, do not turn off until I have force him.   If I have the task of reading running (in a loop remember if I can monitor the pressure) the writing of acts task still more wiggy.  When I start the task it takes perhaps 100-200 ms with the modulated signal and stops.  Fourth start-up, the signal going back straight to high and remained there until this that forced to withdraw.

    So, is it a kind of limitation on this old material on reading and writing (at least a waveform) at the same time?

    The writing task was originally created in the front of the loop and I tried to create it daqmx and using this, but it made no difference.  I use a schedule vi daqmx to set the frequency of sampling clock based on the same waveform with a setting of finite samples.

    Any thoughts are appreciated.  It's not stop me from going forward, but I would like to know why it is the way it is.

    Thank you...
