Sensor Composition
- Nov 20, 2018 -

Sensors generally consist of four parts: sensitive elements, conversion elements, conversion circuits and auxiliary power supply. Sensors directly sense the measured data and output physical quantity signals which have a definite relationship with the measured data. Conversion elements convert the physical quantity signals output by sensitive elements into electrical signals. Conversion circuits are responsible for the output of conversion elements. The electrical signals are amplified and modulated, and converting elements and transformation circuits generally need auxiliary power supply.
