Can NI-9237 use for the temperature measurement ?

I have a NI9174 chassis and NI9237 USB cDAQ but only use 1 port.

Can I use the rest of 4 port to acquire other analog input such as temperature (Thermocouple) and position sensor?

Please asvise. Thanks !

(I am a newly LabVIEW and control engineer.)

In a certain range you can use it to measure resistive sensors.

However take a look into the spec for possible ranges. Maybe you have a pure voltage mode....

 

In half bridge mode:

Temperature with a Pt1000 and a 1k reference resistor (vishay 102??)  . Pt100 in quaterbridge?? (isn't the nominal quaterbridge in the 300 ohm range????)

Position with a potentiometer sensor, for full range of the sensor with two additional resistors to meet the mV/V range.

Scaling may/will need some additional math..
