Hi! I am currently looking to expand our lab's capabilities by adding string pots to our sensor tool kit. I came across a string pot that will work for us, namely Celesco SP2 or SP3 (either one). Here is the website where more information is listed about these sensors:

The SP2 has a voltage divider output. According to the Application Engineer, a very clean DC voltage signal should be sent to the SP2 string pot for it to generate accurate measurements while the SP3 will take a 24 V DC signal (less clean signal) and generate accurate measurements making the SP3 more expensive than the SP2. (would prefer to go with the best value option).
Currently we have a cDAQ-9178 chassis. Is there a NI Analog Input module out there that will work with the SP2 or SP3 string pot. The expectation is that this module will be plugged into the cDAQ-chassis and the wires from the string pot will be run to this module.
Would it also be possible to use a USB-6003 with the above string pots? Let me know and thanks for your help! I have also attached the respective data sheets for your reference.
