You find sensors in smartphones, automobiles, security systems and even everyday objects like coffee makers! S. Hussain Ather is a Master's student in Science Communications the University of California, Santa Cruz. It is used to measure volume, liquid level, density etc. Pressure transducers are of the greatest utility for industrial and laboratory data acquisition and control applications. Applications. A general pressure transducer can also suffer from clogging as a result of iron hydroxide and other materials forming as precipitates, damage from acidic environments or corrosion due to gas for their uses in mining environments. The most common application is in microphones where sound pressure is converted into an electric signal and this electric signal is amplified to produce a louder sound. The piezoelectric transducer is used for dynamic measurement only. As strain is applied to the gauge, the shape of the cross-section of the resistance wire distorts, changing the cross-sectional area. Some of these types of transducers have their applications in everyday appliances, like how piezoelectric transducers are used in electric cigarette lighters in which, when you press its button, a spring-loaded hammer strikes a piezoelectric crystal that creates a voltage across a spark gap to ignite gas. Fig. Ultrasonic sensors are used around the world, indoors and outdoors in the harshest conditions, for a variety of applications. While the number of applications are almost as limitless as the types of pressure transducers, here are some of the most common applications our … For example, proximity sensors are used to detect objects whereas image sensors are used in a camera to capture images. The fact is that the application of sensors is ever-expanding along with the progress in science and technology. Your email address will not be published. One general method that shows how they differ from one another is to compare how transducers convert energy and group them by this. There are some important applications of capacitive transducer which are given below, The capacitive transducers are used to measure humidity in gases. Capacitive sensors are also suitable for applications requiring a high degree of sensitivity at low humidity levels, where they will provide a relatively fast response. Electrical 4 U: Transducer: Types of Transducers And What They Are, Electrical Voice: Inductive Transducers Working Principles and Applications, Amiraj College of Engineering: Electro Magnetic Transducers, Automation Forum: Different types of Photoelectric transducers. Before going in to the details of What is a Sensor, What are the Different Types of Sensors and Applications of these different types of Sensors, we will first take a look at a simple example of an automated system, which is possible because of Sensors (and many other components as well). This makes them pop up in many areas of life from radio antennae to earphones. If you were to induce an electric current across the material, it would undergo a mechanical stress pushing itself together, known as the reverse piezoelectric effect, and both the forward and reverse mechanisms are used in piezoelectric sensors. Metallic objects only. An example application of transducer conversion is a temperature transducer that converts temperature to an electric potential. Virtually all force measurement transducers utilize a spring-like structure, which deforms under the application of a force and a sensor to detect this deflection. Application of Piezoelectric Transducer Crystal microphone measures and records the Heart sounds (Phonocardiography). Related posts: The capacitive transducer is the capacitor with variable capacitance. They are used in metal detectors, brush holders and dryers in car washes, bottling plants, machine tools, motorized valves and many other industrial applications. http://www.efxkits.com/set-of-12-5-in-1-solderless-projects, High DC Voltage From AC in Voltage Multiplier Circuit, Auto Power Supply Control to Ensure No Break Power, Remote Monitoring of Transformer or Generator Health Over Internet, APFC for Industrial Power Use to Minimize Penalty. They are used for sensing, monitoring, control and safety purposes. Capacitive transducers (source: directindustry.com) Capacitive Transducers Contents hide 1. From the microphones at concerts to pH probes that test chemicals for acidity, you'll find transducers in a wide array of applications. Numerous applications use ultrasonic sensors. ​Piezoelectric transducers​ use the piezoelectric effect to convert mechanical stress into electrical energy. Transducers that use ​mutual induction​ measure a quantity such as torque, force, velocity, linear displacement, pressure, acceleration or some other property and react with a change in ​inductance​, the ability of a conductor to oppose an electrical current applied through it. Applications: There are some important applications of piezoelectric transducer which are given below, The piezoelectric transducer is used in spark ignition engines. Temperature transducer is used to measure the temperature of the air such that to control the temperature of several control systems like air-conditioning, heating, ventilation… Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc. They're used in balances as precise methods of measuring the mass of an object or materials placed on them. Similarly, piezoelectric sensors that engineers create can detect pressure variations in sound for use in microphones, pickups for electric guitar, medical imaging and industrial nondestructive testing.
