What is load cell Load cell Coal Handling Plants

 · Hydraulic Load Cells . They are force -balance devices measuring weight as a change in pressure of the internal filling fluid. When a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases. This increase of the liquid is proportional to the applied force.
