Transducers basically are primary element sensors which converts mechanical energy to an electrical signal usually millivots. They are usually the one in contact with the environment or material itself to be measured. A good example for this is the strain gauge. Some of the uses of strain gauges are for force measurement in machine tools, pressure sensors, strain measurement, tension sensors, impact sensors, torque measurement. Before, transducers are enough to make measurements of plant parameters and its output displayed on the field or near the equipment to with measurements taken. From the attached transducer to its visual indication, distances are rather short. But with the evolution of technology and automation, such as power plants and boiler operations, process instruments are now required to 'throw' the readings or outputs over long distances. The transducer's output of millivolts are needed to travel over long distances to the control rooms. That's where electronics come in to compensate signal loss due to resistance and other interference. Thus the transmitters where developed.
