Step[1] Sensing element

This is in contact with the process and gives an output which depends in some way

on the variable to be measured. Examples are thermocouple, strain gauge, orifice plate, particle detector.

If there is more than one sensing element in a system, the element in contact with

the process is termed the primary sensing element, the others secondary sensing elements.

Step[2] Signal conditioning element

Step[3] Signal processing element

Step[4] Data presentaion element
