Parsonics designs and manufactures ultrasonic transducers for non-contact measurement and detection in food processing, beverage, packaging, material handling, and automated equipment.
From liquid and bulk-material level measurement to product detection and distance sensing, our ultrasonic transducers can be integrated into new or existing equipment to help OEMs and engineers solve demanding sensing applications.
Food and beverage equipment often requires reliable measurement without physical contact with the product or target.
Ultrasonic transducers use high-frequency sound waves to detect distance, position, or level. Because measurement is non-contact, ultrasonic technology can be used across a wide range of food-processing, ingredient-handling, packaging, and automation applications.
Parsonics works with OEMs, equipment manufacturers, system integrators, and sensor developers to provide standard and custom ultrasonic transducers for their measurement systems.
Ultrasonic transducers can help measure the level of bulk solids and ingredients stored in bins, silos, and hoppers.
Applications may include materials such as grain, flour, powders, pellets, and other dry ingredients where non-contact measurement is preferred.
The correct beam pattern is especially important when measuring irregular or sloped surfaces because target shape can affect the strength of the returning ultrasonic echo.
Measure the distance to liquids and process materials without placing a mechanical sensing component directly into the product.
Ultrasonic transducers can be incorporated into systems used to monitor ingredient tanks, process vessels, water tanks, holding tanks, and other liquid-storage applications.
Common applications include:
Ultrasonic transducers can provide distance or level information to control systems used in filling, batching, dispensing, and processing machinery.
Because no physical contact with the target is required, ultrasonic measurement can provide a practical solution where moving components, changing product levels, or limited mechanical access make contact measurement difficult.
Use ultrasonic technology to detect the presence, position, or distance of products moving through processing and packaging equipment.
Unlike sensing technologies that rely on target color, ultrasonic measurement operates using reflected sound.
Common applications include:
Parsonics ultrasonic transducers can be incorporated into systems for open-channel flow and process monitoring.
Depending on the application, ultrasonic measurements can be used to determine distance to a liquid surface or incorporated into a larger measurement system for monitoring process conditions.
Ultrasonic transducers measure distance using sound rather than mechanical contact with the target.
This can be useful when measuring liquids, bulk materials, products, packages, or machine components where physical contact is undesirable or impractical.
Ultrasonic waves can reflect from many common industrial materials, including:
Target size, shape, angle, and surface characteristics can influence measurement performance, which is why selecting the correct transducer is important.
Because ultrasonic systems use sound rather than reflected visible light, measurement does not depend on target color.
This can make ultrasonic sensing useful in applications where products, containers, or materials change color or appearance.
Air-ranging ultrasonic transducers contain no mechanical measuring arm, float, or other moving sensing mechanism.
For OEM equipment, this can help simplify the sensing system and reduce dependence on mechanical measurement methods.
Food-processing and manufacturing equipment can expose sensing components to moisture, temperature changes, dust, chemicals, vibration, and frequent cleaning.
Parsonics offers ultrasonic transducers in a variety of housing materials and configurations to help engineers select a design appropriate for the operating environment.
Available housing materials include options such as:
Material selection matters because the transducer housing must protect the internal components without interfering with acoustic performance.
For chemically aggressive applications, Parsonics offers transducer designs with Teflon housings intended for demanding environments.
