Low Profile Weight Transducer 30kg 75kg 150kg 300kg Compact Weight Measurement Sensor
Low Height Weight Sensor FHA is produced based on strain gauge technology with CE
certified. Low profile 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):
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 weight 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 weight sensor FHA-300kg with 2mV/V rated
output powered by 5V DC ,the output range is 0~10mV.
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.
