Miniature Lightweight Load Cell 1kg 2kg 5kg 10kg Weight Measurement
Sensor
Miniature Light Weight Load Cell Sensor FMZK is strain gauge based
to deliver 1.0mV/V output from full wheatstone bridge. Small load
sensor FMZC offers 0.5kg / 1kg / 2kg / 3kg / 5kg / 6kg / 10kg seven
measuring ranges to choose from,high accuracy with maximum 0.05%
non-linearity of the full capacity.The 1000 ohms resistance strain
gauges used are more energy-efficient compared to common 350 ohms
gauges.The compact size and aluminum construction makes FMZK weighs
only about 5.3 grams which makes it suitable for portable weighing
devices or other weighing applications where self-weight matters
like aircraft or drones.Small size weight sensor FMZK offers a
perfect mixture of small size,high accuracy and low cost,which
makes loadcell FMZK suitable for weight monitoring in consumer
electronics.You may find sensor FMZK applicable for home
appliances, force simulators, process control, robotics, automotive
and so on. Forsentek is also capable of and willing to provide
custom made service if you cannot find suitable weight/load/force
measurement transducers from the standard product portfolio.

Small size load cell sensor FMZK is a transducer that converts
mechanical force into electrical signal proportional to the applied
force or weight.The measured load or force causes deformation of
the measuring element(elastic body),the bonded strain gauge deforms
accordingly which will cause the impedance variation of the
wheatstone bridge,under constant power supply, the output signal
changes proportionally, thus the weight or force can be measured by
measuring the output signal from the load cell.
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output is normally within 1mV/V~3mV/V.
Power supply is normally within 3-15V.
Load / Capacity is within 0-1.
So the load cell output signal is normally within
0-45mV(-45mV...+45mV for bidirectional load cell).
Example one: Light Weight Load Cell FMZK-5kg with 1.0mV/V
sensitivity powered by 10V DC,the output range is 0~10mV.
Example two: Lightweight Load Cell FMZK-10kg with 1.0mV/V sensitivity powered by
3.3V DC,the output range is 0~3.3mV.
