Load cell
Load cell A load cell is a transducer which converts force into a measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Introduction Transducer that is used to convert a force/pressure into an electrical signal Electrical output is in the order of a few millivolts and requires amplification by an instrumentation amplifier for further use Load Cells are also called Load Transducer or Load Sensors Force is measured in terms of deflection or strain of elastic member (strain gauge type), increase in fluid pressure (hydraulic type). Types of load cells Hydraulic load cells Pneumatic load cells Strain gauge load cells Hydraulic load cells Hydraulic cells are force -balance devices, measuring weight as a change in pressure of the internal filling fluid. In a rolling diaphragm type hydraulic force sensors, a load or force acting on a loading head is transferred to a piston that in turn compresses a filling
