A force transducer measures the applied force from the proportional deformation of a spring element and converts it into transmitted output signals sent to indicators, controllers, data acquisition systems and computer systems. As a general force measurement rule, the greater the amount of force, the more the spring is deformed.
A system of parts rather then a single piece of machinery, force transducers are common in many industries for many applications. The manufacturing, automotive, medical, defense and assembly line industries use force transducers in applications like quality assurance in manufacturing and assembly, press monitoring, biomechanics, product testing, materials testing, dynamic weighing of moving vehicles and wheel force measurement.
They are also used in the home as kitchen scales and small, portable tire pressure gauges. These force measurement systems produce data by analog or digital electronic, pneumatic or hydraulic outputs.
