I) PRIMARY SENSING ELEMENT This is the element that first receives energy from the measured medium and procedures an output depending on some way on the measured quantity (measured).  The output is some physical variable e.g. displacement or voltage. An instrument always extract some energy from the measured medium. The measured quantity is always disturbed […]

Resistive Load Resistive loads can be purely resistive or of the tungsten-heater load type. A resistive load that has no heating element is the easiest for a switch to handle, and the switch’s rating is based on this type of load. A resistive load is one in which 100% of the load is composed of
