NIST traceable calibration for load cell excitation

NIST traceable calibration for load cell excitation

NIST traceable calibration for load cell excitation

(OP)
We are putting together a force measurement system using load cells and PC-based data acquisition boards.  These components come with NIST traceable calibration certificates.  However we have not been able to find a device to provide the excitation voltage and signal conditioning for the load cells that includes a NIST traceable calibration certificate.

Does anyone have any suggestions?

RE: NIST traceable calibration for load cell excitation

It seems to me you should concentrate on using calibration weights which are NIST traceable.  Then once your system is calibrated you could say your whole system is traceable.

RE: NIST traceable calibration for load cell excitation

The individual components do not need to be NIST traceable.  Together they form a complete calibration system.  The instrument(s) used to calibrate this system is what needs to be traceable.  We manufacture 16 to 22 bit PC based load cell data aquisition cards with onboard signal conditioning and excitation.  We calibrate the boards excitation using a nist traceable DVM.  Once thats done, we calibrate the boards mV/V input using a nist traceable load cell simulator.
