3. Introduction • Ultrasonic machining is a mechanical type non-traditional machining process employed to machine hard and brittle materials (both electrically conductive and non conductive material) using an axially oscillating tool at ultrasonic frequencies [18–25 kilohertz (kHz)]. 2. Advantages of Capacitor Transducers 3. The PowerPoint PPT presentation: "Pressure Transducers" is the property of its rightful owner. Definitions: Transducer and sensors • Transducer – a device that converts a primary form of energy in to a corresponding signal with a different energy form Primary Energy Forms: mechanical, thermal, electromagnetic, optical, chemical, etc. Transducers Prof. B. D. Kanani, EE Department Electrical Measurements and Measuring Instruments (2130903) 1 5.1. Transducer Seminar PPT with PDF Report What are transducers? attainable are not as high as in mechanical transducers. Some of the advantages are: 1. The primary transducer includes electrical & mechanical devices. Definition and General Concept of Transducer Definition The transducer is a device which converts one form of energy into another form. The electric or electronic system can be controlled with a very small electric power. (examples to follow) • Used to change information into a form that can be easily transferred, stored, processed, interpreted, etc. Electrical amplification and attenuation can be done easily and that to with a static device. PowerPoint slide on Digital Transducers compiled by Jandeep. The main function of a second transducer is used to change the signal from mechanical to electrical. mechanical motion of a pointer.
