    A transducer predominately converts one form of energy into another form. A sensor, which although also does this, performs this conversion not as a primary function of itself. Its primary function is to generate a signal (which may not be electronic) that is then fed to another item of equipment, so that a consequent action takes place.

    Examples: The cartidge in a record-player is a transducer: converts mechanical energy into electrical energy. A photo-electric cell, although it converts light energy into electrical energy, is really a sensor: it generates an electrical signal in response to the presence of light.

    As you can see, the dividing line between 'transducer' and 'sensor' is a fine one!
