Power Sonics exclusive designs are known as the Type IP ultrasonic transducers. Typically each transducer requires a one kW generator to drive it and has a radiating surface of approximately 100 square inches. They are designed to be mounted in just about any position, depending on the cleaning application.
Faster, the Type IP transducer because of the lamination design and layout achieves more even cavitation, which result in a transducer which achieved cavitation easily and quickly. The lamination design produces higher cavitation intensity that is more evenly distributed throughout the cleaning area.
This type of magnetostrictive transducer design consists of individual laminations driven by a common coil. Coverage of the radiating surface with laminations results in a high intensity design capable of being driven at high power densities. Levels of 10 Watts per square inch of lamination are typical with this approach.
The high efficiency of this new transducer design also reduces stress on generator components, which results in extended generator life. Type GM, GL and GP generators power these immersibles.
Other advantages of the lamination material are mechanical, electrical and thermal toughness. Low voltage excitation and continuous polarization support the high efficiency design. The "Synergistic" driving action of the radiating surface allows the IP transducer to be driven at the highest usable power levels for achieving effective cavitation.

Ultrasound level sensor SIMATIC PXS
Recording of fill levels from a distance of 3 cm to 10 m
Our sonar proximity switches sense objects of varying materials, shapes, colors or consistencies with absolute precision, flexibility and reliability.
The ultrasound level sensor is proper for level applications in containers due to its design and its technical constructions. The devices feature two switching outputs to which different distances can be assigned. This allows, for example, the minimum and maximum fill level in a tank to be evaluated. Regardless whether the objects are liquid, solid, powdery or even transparent.

Short ultrasonic pulses between 10 kHz and 70 kHz are emitted by the transducer. These pulses are reflected by the product surface and received again by the transducer. They spread with sound velocity and the time from emission to receipt of the signals is proportional to the level in the vessel.
Latest microprocessor technology and proven ECHOFOX® software select the level echo from a number of false reflections and measure it exactly.
Just by entering the vessel dimensions, a level-proportional signal can be displayed. An adjustment with emptied and filled vessel is no longer necessary!
Thanks to different emitting frequencies, levels can be detected in a measuring range between 4 m and 70 m. Optional swivelling holders enable an ideal positioning of the sensors in the solid area.
Fluctuations of the product compositions or complete product changes do not influence the measurement results. A new adjustment is not necessary.
Advantages
- Non-contact
- Independent of product characteristics
Applications
- Level measurement of solids and liquids
- Good chemical resistance

Pulsar's innovative dB range of transducers has taken ultrasonic level measurement into a new era. Unlike the high voltage, frequency dependent transducers of other manufacturers, which require special, protected interconnect cables, or low powered transducers built with intrinsic safety rather than performance in mind, the dB series combines low electrical power that meets intrinsic safety requirements with extraordinary high sonic power to give range and performance.

Nivowave
Ultrasonic level measurement with revolutionary Acoustic Wave Technology
For continuous, non contact level measurement UWT GmbH now offers the new Nivowave series -
a solution for measurement where conventional ultrasonic measuring techniques have failed.
Acoustic Wave Technology provides exact measuring results even for long distances and in difficult applications. Dust, foam and environmental noise are problems of the past.
What is the Acoustic Wave Technology?
The Nivowave series emits a high powered acoustic wave transmit pulse hence any losses have a far less effect than in conventional ultrasonic devices.
The receiver circuitry is designed to identify and monitor low level return signals even when noise levels are quite high. Thus the environment conditions do not have much influence on the evaluation of signals. High power with low frequency combined with advanced software and the use of specifically shaped cones lead to successful measurement in a wide range of applications.
Automatic modulation of sensitivity and mapping of false echoes, simple mounting and easy programming cut the costs of commissioning considerably.
The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.

Bats are using this principle since a long time: sending out a sound wave and through the echoes, the distance to an object can be measured very accurate.
