Pressure transducer labview setup

For the following circuit, assuming the pressure transducer is a 1-6v output with a psi rating of 100. how could i design a data aquisition system to display the pressure  in psi.

 

i have roughly built the circuit to out put voltage at Vab = 1V when there is 0 pressure, or 0 resistance at the potentiometer

and vab = 6V when there is 1000ohm resistance from transduce or 100 psi.

 

new to labview would like some assistance in setting up this system

If you have a pressure transducer with a 1-6 V output, why do you want or need a resistive bridge?  Just measure the votlage.  There are many DAQ devices which can measure 1-6 V.

 

I find it unlikely that the pressure transducer has 0 resistance at zero pressure.  So is it a resistive output transducer or a voltage output transducer?  Please indicate the manufacturer and model of the transducer.

 

What version of LabVIEW and what DAQ devices do you have?

Hii 

 

Is this about a Strain measurement ? if it is you may want to refer this 

 

https://www.ni.com/en/shop/data-acquisition/sensor-fundamentals/measuring-strain-with-strain-gages.h...

 

You can check NI DAQ modules for Strain Gauge here : https://www.ni.com/en-us/shop/model/ni-9236.html

 

Is this for Academic purpose or you are actully making one ? If you are thinking to build one, there are some serious factors and formulas (other than R1/R2 = R3/R4) that needs to be considered.

 

You might want to chekc Vishay.com for further details on this. 

 

Let me know if you have anymore questions.

its a question from a text book i am refering to, so i guess it would be a resistive output transducer, connected to the bridge to give a voltage output. wondering what the block diagram would look like for such a thing. There is no specified model number to the transducer.

1. Define your inputs,

2. Define desired output, 

3. Find a Mathematical Relation between them

4. Program the Math part.
