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.
Pneumatic Load Cells. Pneumatic load cells use air pressure applied to one end of a diaphragm, and it escapes through the nozzle placed at the bottom of the load cell, which has a pressure gauge inside of the cell. Diagram of a pneumatic load cell from Instrumentation Today.
