Measurement of Mechanical Quantities, Page 4 Capacitance displacement sensor Principle of operation: o The capacitance between two metal plates is a function of the distance between the plates and the overlapping area of the plates. Materials fee. Other units, such as those of the British engineering system, are still in use in some places, but these are… Vernier height gauge used to measure vertical dimension from reference ground. Generally a bigger unit of power called kilowatt (briefly written as kW) is-used which is equal to 1000W. They mean that with only one unit of measurement you can express any measurement from the smallest to the largest. Steel scale indicates two units that are cm and inches, cm division on one side and inches, on another side.
