TI Precision Labs (TIPL) is the most comprehensive online classroom for analog signal chain engineers. Transducers and Inverse Transducers- -A Transducer can be broadly defined as a device which converts a non-electrical quantity into an electrical quantity. For example , in case of pressure measurement , bourdon tube is a primary sensor which converts pressure first into displacement, then the displacement is converted into an output voltage by an LVDT. Inductive sensor 23 further includes output terminal 51, through which a DC output signal is provided which indicates the pressure in wellhead housing 13 (shown in FIG. The rated electrical power required for operating inductive sensor 23 is 18 to 30 volts dc with a 150 milliamp maximum current. Inductive Transducer is the self-generating type otherwise the passive type transducer. It uses coil or inductor for its construction. A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. ... Converts pressure changes into electrical form.
