how to connect SCXI or PXI with 6 pin pressure transducer

hello, I am trying to connect ASCX series differential transducer to SCXI or PXI , but my difficulty is that it has 6 pins they are

pin 1 external offst adjustment

pin 2 vs

pin 3 +output

pin 4 ground

pin 5 n/c

pin 6 do not use

 my problem is how to connect this sensor to ni 9237..

 

I am attaching data sheet of that pressure transducer

Without spending too much time looking at the documentation, from using previous similar transducers, the primary two connections you are concerned with are the "+output" and the "ground". The other connections are also important, but aren't directly the concern of the Data Acquisition Hardware. The "+output" produces a variable dc voltage relative to the "ground" input that is a product of the applied pressure, with the maximum output voltage, as shown on the chart, indicating maximum pressure. So you would connect those, through a suitably shielded, moderately short length, wire to the "DAQ" analog input. You will also have to supply the transducer with it's required + supply voltage at pin 2 "vs", and the power supplie's negative to the ground. There are whitepapers on this NI site about connecting to data acquistion hardware and I strongly suggest reading them a couple of times as well as anything online you can find. Writing the DAQ software, in LabVIEW or whatever, can be trivial compared to making the correct, low noise, connections to sensor hardware.

 

I didn't read how the offset adjustment signal is produced or its use, figure it is designed to allow you to "tune out" some signal offset caused by differences between sensors of a type (they will not all have the same "fullscale output" as indicated in the chart).

As you proceed, please keep asking.
