The world has seven continents, each with its highest mountain peak. It is becoming more and more popular for climbers to try and climb all seven summits, which are also known as the Seven Sisters. Only a handful of people has succeeded. To reach the top of any of these is a huge achievement.
A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. The various load cell types include hydraulic, pneumatic, and strain gauge.
Piezoelectric load cell. Piezoelectric load cells work on the same principle of deformation as the strain gauge load cells, but a voltage output is generated by the basic piezoelectric material - proportional to the deformation of load cell. Useful for dynamic/frequent measurements of force.
