Ultrasonic transducer – Converter
Email : email@example.com
An ultrasonic transducer is a device that converts electrical ultrasonic energy into ultrasound energy, or sound waves above the normal range of human hearing. While technically a dog whistle is an ultrasonic transducer that converts ultrasonic mechanical energy in the form of air pressure into ultrasonic sound waves, the term is more apt to be used to refer to ultrasonic piezoelectric transducers that convert electrical energy into ultrasound.
Piezoelectric crystals have the property of changing size when a voltage is applied, thus applying an alternating current (AC) across them causes them to oscillate at very high frequencies, thus producing very high ultrasonic frequency sound waves.
The location at which a ultrasonic transducer focuses the ultrasound can be determined by the active ultrasonic transducer area and shape, the ultrasound frequency, and the ultrasonic sound velocity of the propagation medium.
Ultrasonic converters, as an inevitable Frontend of all ultrasonic systems serve the electro mechanical energy conversion. They transform the electric oscillations in mechanical waves or vice versa and form with it the interface between signal processing and measuring section. On account of the high efficiency Piezo ceramics, e.g., from lead-zirconate-titanate as a key component of the ultrasonic converter often become elective.
In addition, the electric-acoustic conversion properties are decisively influenced by her mechanical construction, the well-chosen materials, and the used connection technologies (gluing, soldering, cleaning, welding). On account of the complicated coupling as well as the reaction between electric and mechanical dimensions, an analytic description or optimization of the sound converter is extremely sophisticated. On the other hand, the application specific optimization of the ultrasonic transducer shows the biggest potential concerning functionality and costs of an ultrasonic welding system.
We are offering following services:
• Analysis of the requirements for the ultrasonic converter from view point of the technical demands, the environment conditions, the costs and the manufacturing technology.
• Identification and interpretation of suitable ultrasonic transducers technologies for ultrasonic de-gases, ultrasonic welding and liquids and ultrasonic application in lab, ultrasonic industry, automotives and consumer products.
• Optimization of ultrasound converters with the help of simulation models (FEA).
• Production of experimental models and prototypes.
• Electric-acoustic characterization of ultrasonic transducers and specification of the necessary components.
• Production of prototype series as well as support concerning suitable production technology including quality assurance and the manufacturing introduction.
• OEM delivery of complete ultrasonic transducers.
Special experiences from high power developments in the automotive-area (level, media qualities) as well as from industrial applications (ultrasonic welding, Ultrasonic Cleaning,) in welding phase and liquid phase allow the purposeful solution of your developing task within a given high-class frame and cost frame to us.
