Answer Posted / amit
According to the instrument society of America-- " A Sensor or Transducer is a device which provides a usable output in response yo a specified measurand"
Here the o/p is defined as an electrical quantity and measurand is a physical quantity .but there is a small difference between them.... Sensor is an element that senses a variation in input energy to produce a variation in another same form of energy. Whereas , transducer usage transduction principle to convert a specified measurand into usable output.
ex.... A properly cut Piezoelectric crystal can be called a sensor and it becomes a transducer with appropriate electrodes and input/output mechanism attached to it.
