INTERFACE TECH TALK Resistance Output Vs Rated Output

Resistance Output Versus Rated Output

Rated Output (RO) is the dynamic electrical signal that directly represents the applied mechanical force. Resistance Output is a static electrical characteristic of the load cell's internal circuitry. When you are performing force measurements, you are primarily interested in the Rated Output. This value, in conjunction with your excitation voltage, enables you to accurately convert the measured millivolt signal into engineering units of force in lbf or Newtons. Discover how load cells work at the ultimate force measurement resource hub, Interface ForceEDU.
INTERFACE TECH TALK LOAD CELL CONDITIONING

What is Load Cell Conditioning?

Interface Tech Talk defines load cell conditioning as taking the native signal from a load cell and converting it into a form for further processing or display. The raw signal from a load cell is in the millivolt range. Load cell conditioning is valuable for amplifying, filtering, and converting the raw signal from a load cell.
INTERFACE 101 EXCITATION

Excitation Voltage 101

An excitation voltage is needed to power the load cell and ensure the output signal is accurate. Load cell excitation is necessary to ensure the accuracy and reliability of load cell measurements. Interface provides electrical performance data on all specifications represented as VDC MAX, when applicable.  The data for excitation voltage is listed under the electrical section of a transducer model’s specification datasheet, along with other factors, including rated output, bridge resistance, and zero balance.
