A transducer is a device that converts a physical quantity into an electrical voltage. It consists of a sensor element that "feels" the physical quantity
and a sort of electronic unit converter that makes a voltage out of the signal.
The microphone set (microphone and preamplifier) is a typical example. It senses the sound pressure in Pascal (Pa) and converts it to
some voltage (V) dependant on its sensitivity. How it works, and how well it works is dependent on
the physical construction, the environmental conditions and the working conditions we establish
(polarization voltage, preamplifier voltage etc.)
Each sensor is given a unique name for easy identification.
A sensor administration system is added in this analyzer to make the selection and maintenance simpler for the operator and reduce the sources of error.
