Force sensor a device that converts the amount of force into a relevant electrical signal.Force is the direct cause of change in the motion of matter.Force sensors can detect tension, tension, pressure, weight, torque, internal stress and strain and other mechanical quantities.Specific devices are metal strain gauge, pressure sensor, etc., in power equipment, construction machinery, all kinds of working machine and industrial automation system, has become an indispensable core components.
The force sensor is mainly composed of three parts:
1-- -force sensitive elements (i.e. elastomers, common materials are aluminum alloy, alloy steel and stainless steel).
2-- -conversion element (the most common is resistance strain gauge).
3-- -circuit part (generally enameled wire, PCB board, etc.).
