Difference Between Sensor & Transducer

Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Sensor & Transducer. The basic difference between the sensor and the transducer is that the sensor detects the variation in the physical parameters of the environment while the transducer transforms the physical parameter or nonelectrical quantities into the electrical signal. Both of these are physical instruments used in different electrical devices to measure physical quantities.

The operation of the sensor is that it senses the level of energy and transforms in an electrical signal that can be calculated with the digital meter. But the transducer varies the energy from one form to another. In today’s post, we will have a detailed look at both the transducer and sensor with a detailed compare them to find their differences. So let’s get started with the Difference Between Sensor & Transducer.

Difference Between Sensor & Transducer

Sensor

• It is such a device that is used to detect the variation occurring in the system and send to the main device which can be a computer.
• It needed certain types of devices to operate on

• Its practical installation is in lifts of shopping malls’ lamps operation.
• It is used in different modern applications due to advancement in the field of controllers that helps to make its use in different aspects practical example of a modern senor is MARG
• There is still the use of potentiometer and resistance to control the analog sensors
• The device used to explain the composition of different chemical substances like gases, fluids are called a chemical sensor
• The chemical sensor tells the quantity of material in the form of a signal and then converts the values
• 2 main processes work for chemical sensors first one is recognition and transduction

• The device that is used to send the biological behavior is called biomedicine
• Its basic function is to sense the variation in the parameter and transform in the resultant signal.

• An example of a sensor a proximity sensor, Magnetic sensors, Accelerometer sensors, Light sensors, etc.

Transducer

• Any type of instrument that is used to transform any category of energy in another type of energy is called a traducer.
• It is used to transform signals from one or another type.
• It is commonly used in different fields of life like automobiles, controlling the different systems her electrical signal is mostly used for conversion in different parameters.
• The phenomenon that helps the transducer to convert signals from one to other types is called transduction
• The main elements of the transducer are sensor and signal conditioning.
• Its main function is the transformation of one type of energy to another.
• Examples of transducers are thermistors, potentiometers, and thermocouples.

Transducer Features

• It is the ratio between the highest value of the signal and the low value of the signal measured from the transducer called dynamic range having high this range shows good sensitivity.
• It comes feature to generate a single signal more than one time.

.

• The thermocouple also transforms the temperature measured with the thermometer in the voltage.

Sensor Applications

• These are some applications of sensors.
• To provide protection to the home motion sensors are used with that automation door system is used.
• Photosensor is used for the detection of infrared and ultraviolet light.
• For the detection of screen rotations, the accelerometer is used.

Sensor vs Transducer

• The sensor is an instrument that detects changes in the physical environment and the transducer converts one type of energy into another type of energy.
• The transducer consists of the sensor as a component and the sensor does not have any transducer
• The sensor is a half element and the transducer is created through a combination of sensor  and signal circuits
• Sensor transforms physical quantities into a non-electrical signal and transducer converts physical energy into electrical
• The sensor needs extra circuitry to convert its output signal into a readable form and the transducer does not need any extra processing circuit.
• The output of the sensor is analog and the transducer generates an analog and digital output
• The putout of the sensor cannot be given to any other system directly but the output of the transducer can be given to any other system directly
• The sensor does not need any outer power supply to work and the passive transducer needs an outer power source for operation
• The sensor is not bidirectional and the transducer is a bidirectional device
• The sensor is a simple circuit device and the transducer is a complicated
• Examples of sensors are thermometers, pressure, sensors, and tight sensors and examples of transducers are thermistors, potentiometers, and Hall effect transducers

Examples of a Transducer

Thermocouple: 

• The thermocouple is a type of transducer that is used for measuring temperature. Thermocouples are used in industries, labs, and HVAC systems for measuring temperature. T

Microphones:

• Microphones are also transducers. They transform sound waves moving through the air into electrical signals. These electrical signals amplified, recorded, and transmitted for different uses such as  audio recording, telecommunication,etc.
