IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...
A technician (right) performs a Guided Wave test. An example of pipeline inspection using guided wave testing (GWT). Mechanical stress wave is generated via transducer array mounted around the pipe surface. The electrical signal is driven by the portable electronic unit.
A sensor, which is a type of transducer, is a device that converts a physical property into a corresponding electrical signal (e.g., strain gauge, thermistor). An acquisition system to measure different properties depends on the sensors that are suited to detect those properties.
Using EMAT, the requirements to surface smoothness are less stringent; the only requirement is to remove loose scale and the like. Easier for sensor deployment. Using piezoelectric transducer, the wave propagation angle in the test part is affected by Snell's law. As a result, a small variation in sensor deployment may cause a significant ...
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] 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.).
A smart transducer is an analog or digital transducer, actuator, or sensor combined with a processing unit and a communication interface. [ 1 ] As sensors and actuators become more complex, they provide support for various modes of operation and interfacing.

The transponders reply, and the replies are received again by the diver station (A). Signal run time measurements now yield the distances A-B, A-C and A-D, which are used to compute the diver position by triangulation or position search algorithms. The resulting positions are relative to the location of the baseline transducers.
