Cheap load cell 1kg 2kg 3kg 5kg 10kg 20kg Weight Measurement Transducer
Low Cost Weight Sensor FHD is available in 0-1kg / 0-2kg / 0-3kg /
0-5kg / 0-10kg / 0-20kg six measuring ranges with 1.0 mV/V output
from full wheatstone bridge bonded on aluminum structure. Micro
load sensor FHD delivers good accuracy with compact
size(80x12.7x12.7mm), can be loaded in both tension and compression
direction. You may find cheap load cell FHD ideal for mass
production applications such as force simulators, home appliances,
Arduino based weight measuring projects, and so on.

A load cell sensor is a transducer that converts mechanical force
into electrical signal which is proportional to the weight being
applied.The measured load or force causes deformation of the
measuring element,the bonded strain gauge deforms accordingly which
will cause the resistance change of the wheatstone bridge,under
constant power supply,the output signal between Sig+ and Sig- will
change proportionally,thus the load 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: 1.0mV/V load cell with 5V power supply,the output
range is 0~5mV (-5mV...+5mV for bidirectional sensor).
Example two: 1.0mV/V load cell with 3.3V power supply,the output
range is 0~3.3mV (-3.3mV...+3.3mV for bidirectional sensor).
