Low Profile Force Transducer 3000N Compression Load Cell 300kg Weight Sensor
Low Profile Compression Force Sensor FHA is produced based on
strain gauge technology with CE certified. Compact compression load
cell FHA offers 0-30kg / 0-75kg / 0-150kg / 0-300kg four measuring
ranges to choose form, high accuracy with 0.05% non-linearity of
the full capacity. Low profile load cell FHA utilizes 1000ohms
gauges which has better performance compared to commonly used
350ohms gauges in terms of power consumption and long term
stability. Compact design enables the construction of scales with
an extremely low overall height, affordable load cell FHA is
also suitable for battery powered weighing devices.

Brief instruction of Rated output(or Sensitivity):
Load cell zero output: The output signal of the loadcell with
no-load applied,expressed in mV/V or as a percentage of rated
output.The zero output is caused by the stress during strain gauge
bonding,it can be handled during calibration or signal processing
without affecting the measurement accuracy.
Definition: The signal produced by load cell(or force transducer)
when rated load is applied, expressed in terms of mV/V. The rated
output indicates the output signal range of the sensor.
Sensor output = (Power supply * Rated output) * Load / Capacity
Rated output of thin force sensor FHA is normally within
1.5mV/V~2.0mV/V.
Power supply of compact load cell FHA is normally within 3-10V.
Load / Capacity is within 0-1.
So the output signal range of weight transducer FHA is
normally within 0-20mV.
Example one: Planar beam load cell FHA-30kg with 1.5mV/V rated
output powered by 10V DC ,the output range is 0~15mV.
Example two: Low profile force transducer FHA-300kg with 2mV/V
rated output powered by 5V DC ,the output range is 0~10mV.
