Load cell - wich modules and wich Analog Input?

Hi, I have a CDAQ-9135. I need to connect a load cell. I have tried various configurations and have not been able to configure it. Here is the technical information of the load cell

https://www.wika.com/media/Data-sheets/Force/Bending-beams-shear-beams/ds_fo5121_en_co.pdf

I have a number of questions:

1) which module is appropriate to use in this case?
I have the modules 9219 - 9237 - 9215 -0203

2) Which Analog Input should be used?

Thanks

The load cell is a simple bridge-type sensor, so you should use the NI9237 made for bridge-type sensors!

See your datasheet and this NI document to connect your sensor to the module…

Hi GerdW

 

Thank you for your reply.

 

I forgot to say one important thing, our cell inside is amplified.

I report the technical diagram

 

I was thinking of using the NI9203 module, it is correct? Can I use also NI9291?

Should the power supply to the load cell be from the outside? Is there any way to power the load cell using a module? Thank you

Why do you link to a datasheet when you use a completely different sensor???

The sensor outputs a current signal: only the NI9219 is able to measure current (directly)!

As I guess you can read datasheets too: what exactly is your question?

Is any of your modules able to output 10-12Vdc with enough power to supply your sensor?

(Again: I guess you can read datasheets too…)

Best regards,
