Health o meter^® - How Scales Work

Dial

Weight is evenly distributed through the brackets and levers
Long levers connect to a plate with spring
Spring stretches in proportion to the weight imposed
Pivot translates the up-and-down to side-to-side motion
Rack and pinion translates the side-to-side to rotation motion
Dial or indicator will turn and correct weight will appear in the window

Digital

Weight is evenly distributed through the brackets and levers
Long levers are connected to a beam
A strain gauge is bonded on the beam
Deflection of beam causes the change in resistance
Output signal is translated to weight reading on LED display

Body Fat Monitoring

Weight is distributed through the load cell at each corner of the base
A strain gauge is bonded on each load cell
Deflection of diaphragm causes the change in resistance
Output signal is translated to weight reading on LCD
Safe electrical current passes through the body fat to measure the impedance
Body fat percentage is displayed on LCD in seconds
