What is the basic function of sensors?
To receive signals from physical systems
To convert signals into a more useful form
To process signals for analysis
To generate signals without external power
Sensors receive signals from physical systems and convert them into a more useful signal, such as electrical, mechanical, optical, or chemical.
An element of measurement can have several functions, such as signaling, indication, registration, integration, and transmission.
The primary element of a sensor is the part of the instrument that first uses the energy of the measurement medium to produce a condition that represents the measured variable.
The secondary element of a sensor converts the condition produced by the primary element into a useful condition for the instrument's function.
