I am having trouble Omega PX209-30v45G5v Pressure Transducers

Solved!
Go to solution

I'm trying to connect my pressure transducer to labView, but currently no lucky with that. I have tried wiring thr connection differently, but no results please help me i have attached my wire plot.

What is the value of that resistor you have wired in between 0 and ground?

Why do you have that there?

 

When you say "no luck", what does that mean?  Do you have an error message?  Are you getting 0V signal?  A signal of some level but not what you expected?

 

Please provide details of how it isn't working!

500omhs it shows no signal. I have just tried an new way it shows signal but not correct reading, because it should give me 14.7 atmospheric pressure not only giving me around 2psi

Why would you be using a resistor?  It is like you wired it up to convert a current output sensor to be able to measure the voltage across a 500 ohm resistor.  However you sensor part number is a 0 to 5 V output.

 

Instead of giving us pictures of wires, can you draw a schematic of how you wired it up?

I don't see where your black wire is going in the pictures.  It's like it is not connected to anything.

 

I think you have this wired up all wrong.  Did you wire it up according to the manual?  https://assets.omega.com/manuals/M4085.pdf

Dear labView experts,

 

I currently have 4 pressure sensor of 2 read current  and 2 read voltage. But I'm having issues having all 4 sensor in one daq USB-6001 due to channel output only takes current or voltage. How can i fix this issue where I can have all 4 sensor connect to one daq.

Your USB6001 only reads voltages - it cannot read current directly.

For reading current signals you (simply!) need to apply a shunt resistor (which is basic knowledge for anyone doing electrical measurements)!

But have a look into the 6001 specs/manual ... I remember something like a input impedance of 110k .. ... but if you use a 6001 accuracy is usually not recommended 😄

Buy a signal conditioner that converts current to voltage. You can purchase a 0-20 mA or 4-20mA to voltage signal conditioner and this would make it so you can use the card you have.

Why did you start a new thread when you already asked the question here.  https://forums.ni.com/t5/LabVIEW/I-am-having-trouble-Omega-PX209-30v45G5v-Pressure-Transducers/m-p/4...and marked my message as the solution where I told you the same things?

That was to connect the pressure sensor with wiring. This is to make all my pressure sensor working together. I have tried stunt between the positive and negative but it does not give any readings. Also, I tried using two daq one for current and other for voltage but it gives an error that two same daq are working. I also have an flow meter which reads voltage, but it does not like it that either since the first daq is reading current.  What would be the best solution for this kind of problem.
