Finally, differential pressure sensors measure the difference in pressure between two points in a system. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. In fact, sensors are a type of transducer, and a transducer can contain sensors — although a transducer in and of itself is not considered a sensor. What’s the difference between a sensor and a transducer? Sensors can be defined as an element that senses in one form of energy to produce a variant in same or another form of energy. A sensor and transducer have similar functions, so it is understandable that there may be some confusion between them. These outputs can transmit over long distances. Because, transducers are sometimes found in sensors.The main difference between sensor and transducer is, the sensor is a physical device, that senses a physical quantity and then converts it into signals which can be read by an instrument or the user. The main difference between sensor and transducer is that a transducer is a device that can convert energy from one form to another, whereas a sensor is a device that can detect a physical quantity and convert the data into an electrical signal. Once the details are described to define the output signal and application, the proper term can be set. A transducer refers to a kind of device that is employed in converting one form of energy to another. EXPERIMENT NO. The change in resistance is measured by the ac or dc measuring devices.The resistive transducer is used for measuring the physical quantities like temperature, displacement, vibration etc. Intrinsic Breakdown. All these and many other automation tasks are possible because of Sensors. Some transmitters can provide additional data about the device or process measured as part of the communication.
