I am experimenting with load cells and I was just wondering what the term mV/V means.
The excitation voltage of the load cell is 10V with a 2 mV/V output rating. I am assuming the maximum output should be 20mV.
The selectable ranges of my analog input card are :
0-39.0625mV, +/-39.0625mV, +/-78.125mV, 0-156mV, +/-156mV, and 0-1.25V.
The maximum excitation voltage on the load cell is 15V so I was hoping to use a 12VDC power supply, the analog card in the 0-39.0625mV range, and the load cell.
Will this work? With a 12VDC excitation voltage I should get a maximum output of 24mV.
The input impedence of the analog card is 5Mohms.
The input resistance of the load cell is 350ohms min. and the output resistance is 350ohms.
