WHAT YOU NEED TO KNOW ABOUT WELDING TRANSDUCER
Welding transducer is an energy conversion device. There are several parameters to consider when evaluating it ,or analysing its performance description. The parameters include the following;
· Electrochemical coupling coefficient
· Resonance frequency
· Impedance characteristics
· Frequency bandwidth
· Transmission and reception sensitivity
· Mechanical quality factor
· Directivity and many more.
Types of Transducers
Transducers come in a variety of forms and each possesses some unique performance characteristic. For instance, the emissive transducer offers high energy conversion efficiency as well as a large power output. Meanwhile, the transducing transducer will supply high resolution, high sensitivity and a wide frequency. Hence, when designing a transducer, the application of the transducer will influence the designs of its unique parameters.
The operating state of the transducer is determined by two equations. The state of the circuit equation and the equation to get its mechanical vibration. The mechanical vibration equation shows the relationship between the vibration velocity and the force in the system.. Likewise, the circuit system equation describes the parameters for vibration in a circuit.
Transducers are known to have both their circuit system and mechanical system together in a couple. Therefore it comes as no surprise that mechanical vibrations will trigger some change in the circuit system. Similarly, changes in the circuit will lead to vibrational changes in the mechanical system. Hence, both the mechanical and circuit equation of for the transducers help to define the operations and behaviour of the transducer.
A piezoelectric transducer is a device that is able to use the piezoelectric effect to convert both acoustic and electrical energy. Piezoelectric effect can be defined as a way to convert electrical signals to mechanical vibrations. The piezoelectric transducer is durable, made of low-cost materials, and possesses high-elect-acoustic efficiency and is easy to manufacture.
