Hi Everyone,
First post here as this is my first jump into a NI based data acquisition system.
I have a setup where i am monitoring 5 high pressure transducers (Omega PX41 2 wire style output) 24v power supply exciting the transducers and feeding the negative to a NI USB 6002 to their respective AIX + inputs and grounded properly. I have a 250 ohm shunt resistor between the AIx positive and AIx negative.
On 4 of the 5 readings are great using max to read voltage. However i am getting 10+ volts on 1 of my channels and the resistor is getting super hot. I replaced the resistor with no change in performance. Verified wiring to sensor is good. I guess one question i have is should i have the Shunt resistor between the AI ground and AIx+ or AIx- and AIx+?
Not sure where to go from here hence this post. Thanks!
