    • Load Cell/Point Input/Output Measurements
      • b. The expected output from each load cell/point depends on the mV/V rating of the load cell/point and the weight. For example, a 2mV/V load cell/point will respond with a maximum of 10 mVDC at full system weight capacity, which includes the weight o...
      • c. A zero reference point will vary from system to system depending on the “Dead Load” of the vessel. “Dead Load” is the weight of the vessel and appurtenances only, with no product loaded. In our example we will assume the dead load to be 50...
