Sensor?? Detector?? Transmitter?? Transducer??




Sensor's Definition:




Any device could detects any type of energy (such as heat, pressure, ray, motion, magnetiszm and etc.) to the system of detection.


example : ( pressure sensor, position sensor, heat sensor and etc)






Transmitter's Definition:




Any device used to transfer or convert any form of signal that suitable for the system become usable.


example: (Op-amp Amplifier)


















Ttransducer Definition:






Any device used to convert one type of energy to another type of energy.Generally, its include sensor and transmitter.


example: a temperature transducer sense heat and convert those heat into an electrical energy, then sends those signal to a process control system as a feedback signal or a variable in a process controll system.
