In the modal test of lightweight structures, the measured data is easily polluted by mass loading effects of transducers. The following are the application of the transducers. Future of Transducers. For example, a voltmeter must have a high-impedance input in order that the voltage measurement does not significantly alter circuit current and, hence, alter the voltage being measured. It must be highly sensitive to desired signal and insensitive to unwanted signal. Common examples include microphones, loudspeakers, thermometers, position and pressure sensors, and antenna.Although not generally thought of as transducers, photocells, LEDs (light-emitting diodes), and even common light bulbs are transducers. It consists of a pair of parallel plates with the middle plate moving with pressure and producing a differential capacitor system. 6. View Answer, 3. Reliability and Stability. It should have good resolution over the entire selected range. a) using shock absorbers Transducers may have single or multiple inputs and/or outputs. Product Details. A transducer must be able to perform in any environment. The structure reacts to the applied load and focuses that load into an isolated, uniform strain field where strain gauges can be placed for load measurement. Transducers function best when mounted very low under the hull, away from cavitation sources, and must automatically "kick-up" when striking an object. 1.5 feet to the right of the motor looking at the back of the boat) well as worked with different angles. A transducer is a device that converts energy from one form to another. Selecting a Sensor Location . The idea I have is an air-coupled flexural transducer with a PZT disc. View Answer, 6.
