Glass feedthrough for ultrasonic transducers under high pressure
We have developed a product on a glass feedthrough for use in a high-pressure environment and for flushing with aggressive media. Here, individual transducers or a quartet of four pulsed transducers are provided with a polyurethane sheath and contacted via stranded wires. These run onto the glass feedthrough, which fulfills the highest demands as a seal. As SECO transducers do not require a sensitive diaphragm, use under pressure is not a problem. As long as they are evenly surrounded by pressure, they work absolutely reliably even with pressure fluctuations.
Both the chemicals used and the contacting are designed so that they can be used reliably in a gas atmosphere.

Why glass feedthrough?
Ultrasonic transducers on glass feedthroughs play a crucial role in high-pressure applications, particularly in the measurement and monitoring of gases. These transducers are based on piezoelectric technology, which makes it possible to convert electrical signals into ultrasonic waves and vice versa. They are often used in industrial processes where high pressures and temperatures occur to precisely measure parameters such as density, flow or composition of gases.
Glass feedthroughs serve as an interface between the ultrasonic transducer and the medium to be measured. They provide reliable insulation and protect the transducer from extreme conditions, which are common in high-pressure applications. The choice of glass as the material for the feedthrough is particularly advantageous as it is chemically inert and has a high resistance to pressure and temperature fluctuations.
In high-pressure applications with gases, the reliability of the ultrasonic transducers is particularly important as they often have to work under extreme conditions. The glass feedthroughs must therefore not only withstand mechanical loads, but also ensure perfect sealing to prevent gases from penetrating the transducer. They must also enable the transmission of ultrasonic waves without significant losses.
The application of such systems can be found in various industries, including the oil and gas industry, chemical production and power generation. By using ultrasonic transducers on glass feedthroughs, companies can optimize their processes, increase safety and at the same time ensure precise measurements under difficult conditions. This not only helps to increase efficiency, but also to comply with strict environmental and safety standards.
