Load cell glossary:
Load Cell:A device which produces an output signal proportional to the applied weight or force.
Wheatstone Bridge:A Wheatstone bridge is a network of four resistive legs. One or more of these legs can be active sensing elements. The Wheatstone bridge is the electrical equivalent of two parallel voltage divider circuits. R1 and R2 compose one voltage divider circuit, and R4 and R3 compose the second voltage divider circuit. The output of a Wheatstone bridge is measured between the middle nodes of the two voltage dividers.
Excitation: The voltage applied to the input terminals of the load cell.
Rated Capacity: The maximum axial load the load cell is designed to measure within its specifications.
Non-linearity: The maximum deviation of the calibration curve from a straight line drawn between the no-load and rated outputs; expressed as a percentage of the rated output and measured on increasing load only.
Non-repeatability: The maximum difference between load cell output readings for repeated loadings under identical loading and environmental conditions.
Hysteresis: The maximum difference between load cell output readings for the same applied load; one reading obtained by increasing the load from zero and the other by decreasing the load from rated output; usually measured at half rated output and expressed in percent of rated output.
Creep: The change in load cell output occurring with specified period of time, while under load, and with all environmental conditions and other variables remaining constant; usually measured with rated load applied.
Safe Overload: The maximum load in percent of rated capacity which can be applied without producing a permanent shift in performance characteristics beyond those specified.
Ultimate Overload: The maximum load in percent of rated capacity which can be applied without producing a structural failure.
Operating Temperature: The extremes of temperature within which a load cell will operate without permanent adverse change to any of its performance characteristics.
Temperature Shift Span: The change in output due to a change in load cell temperature; usually expressed as a percentage of load per degree Celsius change in temperature.
Temperature Shift Zero: The change in zero balance due to a change in ambient temperature; usually expressed in percent of rated output per degree Celsius change in temperature.
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of loadcell FMXD is normally within 1mV/V~2mV/V.
Power supply of weight transducer FMXD is normally within 3-12V.
Load / Capacity is within 0-1.
So the output range of FMXD is normally within 0-24mV(-24mV...+24mV for tension/compression force measurement).
Example one: FMXD-500N with 2.0mV/V rated output powered by 3.3V DC,the output range is 0~6.6mV.
Example two: FMXD-1kN with 2.0mV/V rated output powered by 5V DC,the output range is 0~10mV.
