Dual output ultrasonic generator: principle - advantages - applications - trends
Date: 2025-12-11Read: 7
In industrial fields such as precision machining and material separation, ultrasonic technology has become one of the core supporting technologies due to its high efficiency and precision. Among them, the dual output ultrasonic generator, as the key core equipment of the ultrasonic system, greatly expands the application scenarios and adaptability of ultrasonic technology with its unique advantage of being able to drive multiple loads simultaneously. This article will take Artech's imported PNS dual output ultrasonic generator as the core, and comprehensively analyze the technical value and application prospects of the dual output ultrasonic generator from four dimensions: working principle, core advantages, application fields, and industry trends.
1、 Core working principle: Technical logic of variable frequency drive and multi load coordination
The core working principle of the dual output ultrasonic generator is based on variable frequency ultrasonic technology. Through the conversion and transmission of electrical signals, it provides stable and adjustable high-frequency electrical signals for the ultrasonic transducer, which are then converted into mechanical vibration energy and applied to the target scene. Unlike traditional single output generators, the dual output model has two high-frequency cable output channels, which can activate multiple mechanical structures (such as multiple screens and transducers) simultaneously by one generator, achieving uniform energy distribution and collaborative work.
Taking Artech PNS dual output ultrasonic generator as an example, its core technical logic lies in dynamic frequency adjustment and adaptive matching. The equipment can dynamically change within the frequency range of 30-38kHz, and by regularly searching and readjusting the ideal operating point, it ensures the stability of energy output under different working conditions. This frequency variability requires the generator to have robust current and voltage processing capabilities. Artech's specially designed electrical box can effectively cope with the strong current and voltage generated when the frequency changes, while complying with Atex Zone 22 explosion-proof standards to ensure safe operation in industrial scenarios.
From the perspective of system composition, the dual output ultrasonic generator is not an isolated device, but rather a core component integrated into a complete ultrasonic system. Taking the Artech screening system as an example, its complete composition includes a pre tensioned screen, an ultrasonic generator (dual output core), a transducer, a waveguide rod, a screen waveguide, an HF cable, and a connecting bracket structure. Each component is coordinated and linked through the dual output channels of the generator to ensure accurate energy transmission to the work terminal.
2、 Core advantage: Multiple breakthroughs in efficiency, stability, and high adaptability
Compared to traditional single output ultrasonic generators and other similar devices, dual output ultrasonic generators (represented by Artech PNS) demonstrate core advantages of high efficiency, stability, and economy, which can be summarized as follows:
（1） Multi load collaboration, expanding large-scale application scenarios
The core advantage lies in the ability to activate multiple mechanical structures simultaneously with one generator, which enables it to support the stable operation of large equipment. For example, in the field of screening, a screening machine with a maximum diameter of 3 meters can be designed, and the energy can be evenly and effectively distributed throughout the entire screening screen, solving the pain points of traditional single output generators being difficult to support large equipment and uneven energy distribution, greatly improving the adaptability of ultrasonic technology in large-scale industrial scenarios.
（2） Outstanding precision processing capability, improving material handling quality
For ultra-fine powder processing scenarios, the dual output ultrasonic generator exhibits excellent precision machining capabilities. It can efficiently screen powders smaller than 500 μ m, while effectively dispersing material aggregates, reducing the amount of large particle impurities, and significantly improving the accuracy and purity of material screening. In addition, during the quantitative feeding or conveying process, it can also reduce the adhesion between the material and the container wall, ensuring the stability and accuracy of material transportation.
（3） No mechanical tuning, reducing operation and maintenance costs and operational barriers
The Artech PNS dual output ultrasonic generator does not require mechanical tuning, greatly reducing the difficulty of equipment installation and debugging, and reducing the investment of professional operation and maintenance personnel. At the same time, the design of frequency dynamic changes can avoid or at least reduce the hot spot temperature at a certain point during the working process, reduce the losses caused by local overheating of the equipment, and extend the service life of the equipment. The operation mode of the device supports automatic and manual switching. Under standard circumstances, each system includes an ultrasonic generator, transducer, data cable, and conversion screw, with a simple structure and easy maintenance.
（4） Safe and reliable, suitable for diverse industrial environments
The equipment is designed with an IP65 protection level and a voltage level of II. It can adapt to environmental temperatures ranging from 0-45 ℃ and working conditions with a maximum relative humidity of 80% at 30 ℃. At the same time, the installation level is II, and it can operate stably in indoor environments within an altitude of 2000 meters. Its electrical box meets the Atex Zone 22 explosion-proof standard and can adapt to industrial scenarios with high dust content (such as powder screening workshops), greatly improving its adaptability to different industrial environments.
（5） High cost-effectiveness, balancing performance and cost control
Artech PNS dual output ultrasonic generator offers three power specifications: 50W, 100W, and 200W, making it a cost-effective solution. Compared to DGS models in the same series, although they do not support external communication and front panel strength adjustment for personal computers, their core performance is consistent and can meet the basic needs of most industrial scenarios. At the same time, the dual output design can replace the traditional combination of multiple single output power supplies (such as changing the 2 and 3 power generators of the two-layer and three-layer screening machines to one dual output system), greatly reducing the initial investment and later operating costs of the equipment.
3、 Application area: Fine processing requirements covering diverse industrial scenarios
