How do some bicycle power meters work?
Bicycle power meters are devices that measure the power output of a cyclist. They are typically mounted on the crank arm of the bicycle and measure the torque and cadence, which can then be used to calculate power.
There are two main types of bicycle power meters: strain gauge and optical. Strain gauge power meters work by measuring the strain on the crank arm as the cyclist pedals. Optical power meters work by using a light sensor to measure the deflection of the crank arm.
How do strain gauge power meters work?
Strain gauge power meters work by measuring the strain on the crank arm as the cyclist pedals. The strain gauge is a thin, flexible strip of metal that is bonded to the crank arm. When the crank arm is bent, the strain gauge deforms, which changes its resistance. This change in resistance is then measured by the power meter and used to calculate power.
How do optical power meters work?
Optical power meters work by using a light sensor to measure the deflection of the crank arm. The light sensor is mounted on the frame of the bicycle and shines a light at the crank arm. When the crank arm is bent, the light beam is deflected. The amount of deflection is measured by the light sensor and used to calculate power.
