Difference between Sensor and Transducer
Sensor | Transducer |
---|---|
A device that converts physical parameters to electrical output. | A device that converts energy from one form into another form is known as a Transducer. |
The word Sensor comes from the USA. | The word Transducer comes from Europe. |
The use of a Sensor is for sensing the element itself. | The uses of transducers are for sensing elements and also for circuitry. |
In the Sensor its resistance changes with temperature. | In Transducers its resistance changes with in voltage. |
All the sensors are not transducers. | All Transducers do not contain a Sensor. They use it as a mechanism but do not always rely on it. |
It is a sensor when it responds to a stimulus. | It becomes a transducer when connected to a bridge circuit. |
It detects change in physical stimulus and turn it into a signal. | It transfers power from one system to another in the same or in a different form. |
Examples of Sensors: Temperature Sensors, and Proximity Sensor. | Example of Transducer: Strain gauges, and Piezoelectric Transducers. |
Difference between Sensor and Transducer
In this article, we will see the difference between a sensor and a transducer. But we will see what are sensors and transducers so that we can understand the concept then we will jump into differences.
