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.
The pressure gauge used to monitor the force can be located several metres away from the device by the use of a special fluid-filled hose. In systems where more than one load cell is used a specially designed totaliser unit has to be employed. Hydraulic load cells are self-contained and need no external power.
