pressure input problem

[neron]

hi

I'm trying to get analog voltage input with omega PX300 pressure transducer with SCXI 1102 and SCXI 1300 terminal block. However in labview what was measured  is just noise. Are these devices capable of taking voltage input or the reasun of the problem stems from me. By the way I have also BNC-2110 could it be also used for voltage input

Have you seen this?

Neron,

The SCXI 1102 is a thermocouple module that has a 2 Hz lowpass filter in it, which cannot be disabled (as was mentioned in the article linked by muks).  The SCXI 1300 is just a terminal block for the 1102, which has a built-in CJC for temperature measurements.  You can set up either a temperature tast or a voltage task with the 1102 and 1300.  So, this should work as long as you expect the frequency of your signal to be low.

The BNC 2110 is just a terminal block for a data acquisition card.  What DAQ card are you using?  If you connect this to your DAQ card, it will not have the filtering, so if you connect your transducer to one of the analog input BNC connectors, you should be able to see your signal regardless of the frequency. 

If you are not sure whether your card is reading properly, I would try reading values using Test Panels in Measurement and Automation Explorer.  Connect a constant voltage source, such as a battery, and see if it shows the correct value in the Analog Input tab of the test panels. 

I hope this helps.

I feel that is the key....
