DAQ1500 & 3-wire load cell

[berkinet]

I would like to use the DAQ1500 with a 3-wore load cell

• Sourcingmap - 4pcs Demi Cellule de charge corps Pont Balance Pèse électronique 50 kg Capteur https://www.amazon.fr/dp/B00R1J7VA0/ref ... qDbZ20VMSN

I am guessing I should either short GND and "-" together on the DAQ1500, or just leave GND vacant.

Any pointers?

I've never implemented this before but it sounds like you're looking at something like this:

Take a look at the first answer, it might be what you're trying to do.

I think that’s it. I’ll order the load cells and report back.

Thanks.

Success. The load-cells were indeed 1/2 bridges and the diagram you pointed me to was the key. Once I wired them up correctly and connected them to the DAQ1500 it just worked. well, after more than a little playing around getting the right configuration values to actually make the system useful.

Thanks again.
