Load cell Sensitivity

What is the sensitivity or output in mV/V for the RB-Phi-204 load cell?

Also, is there a datasheet available that includes further details such as non-repeatability, creep, zero balance, etc?

Hi,

These types of load cells usually come with a certificate/calibration sheet from the manufacturer that provides all these information.
Here is an example of a certificate for 500Kg S Type Load Cell

Thanks - Can you comment on the “Allowed Excitation Voltage” of 5~18V. Why does the minimum 5 volts exist?

Isn’t the output of the load cell simply a factor of the excitation voltage? My hardware provides an excitation voltage of 2.7V so the output at full scale (500kg) would be about 5.4mV.

Load cells have a range of voltage supply. The recommended voltage supply for the RB-Phi-204 is 5V to 12V.
The RB-Phi-204 should also work with 2.7V.
Correct, the voltage output at full scale for this load cell should be approximately 5.4mV with 2.7V supply (1.9995mV/V x 2.7V)

Thanks for the detailed reply to both my questions. I’ve ordered two of the load cells.
