  • NI-9237

Issue Details

I am looking at an aerospace pressure transducer with specifications including a 3 mV/V output, and I think this is a bridge sensor. How can I determine from the data sheet that this is bridge based or not? 

Solution

Since there is a ratio of voltage for the output, one can confirm that this is bridge based. Additional specs to confirm this determination include checking for an input / output resistance (ex. 350 ohms) and looking for information on (bridge) completion, if quarter- or half- bridge.
