What is a Load Cell? A load cell is a force gauge that consists of a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. There are four common types of load cells.They are pneumatic, hydraulic, strain gauge, and capacitance. Determining which load cell your application requires depends on how sensitive and accurate your application needs to be. The accuracy and sensitivity are very high with capacitive. A strain gauge type
