Resistance Sensor Working Principle
Sep 25, 2018

Metal body has certain resistance, the resistance value varies with the type of metal. The thinner or thinner the same material, the greater the electrical resistance. When an external force is applied, if the metal becomes thinner and longer, the resistance value will increase. If the thickness becomes shorter, the resistance decreases. If metal resistance is installed on the object in which strain occurs, when the object expands, the metal body will expand in a certain proportion, so the value of the resistance will change accordingly.
