Founded in 1854, O'Fallon's namesake comes from Colonel John O'Fallon who was a wealthy gentleman from St. Louis. In downtown O'Fallon, a Baltimore and Ohio Railroad railroad depot was built, which helped put O'Fallon on the map.
â¢ Transducers and sensors are physical devices that are used in electrical, electronic and many other types of gadgets and appliances. â¢ Transducers are used to convert one energy type into another while sensors measure energy levels and convert them into electrical signals that can be measured digitally.
Transducer - The conversion of energy from one form to another is known as Transduction. A transducer serves for this purpose. Now why there is confusion is that, A Sensor can sense in any form(usually electronic) i.e due to some mechanical change, it can react in electrical form. Thus there is a conversion, similar to that of a transducer. A classic example would be a thermocouple. Or a pressure sensor which might detect pressure and convert it into electric current (3-15psi to 4-20ma) A Transducer is more than a sensor. It consists of a sensor/actuator along with signal conditioning circuits.
