Types of Force Sensors

The main types of force sensors are · Mechanical types. · Hydraulic types. · Electrical strain gauge types. Mechanical type Mechanical types are usually complete measuring systems involving some form of spring such as in a simple spring balance or bathroom scale. It is a basic mechanical principle that the deflection of a spring is directly proportional to the applied force so if the movement is shown on a scale, the scale represents force. Hydraulic type Hydraulic types are often referred to as hydraulic load cells. The cell is a capsule filled with liquid. When the capsule is squeezed, the […]
