About Us

Ultrasonic Transducers Built Around Your Application

Parsonics Corporation designs and manufactures ultrasonic transducers for OEMs, sensor manufacturers, system integrators, and industrial applications where reliable non-contact sensing matters.

From standard transducers to custom designs, we work with customers to match the acoustic performance, housing, mounting, materials, and configuration of the transducer to the requirements of the sensing system.

Ultrasonic Transducer Expertise for Industrial and OEM Applications

Parsonics is a family owned U.S. company based in Woodstock, Illinois, specializing in ultrasonic transducers for industrial sensing applications.

Our transducers support applications for air, gases, to measure distance, presence detection, fill levels, flow rates and wind speed. 

Selecting the right ultrasonic transducer requires more than choosing a frequency. Sensing range, beam angle, target characteristics and drive electronics can all affect performance. Parsonics works directly with customers to evaluate these requirements and select the best solution.

Transducers Designed for the Application

An ultrasonic transducer is one of the most important components in an ultrasonic sensing system. Its frequency, sensitivity, beam pattern, mechanical construction, and interaction with the electronics can directly influence the performance of the finished sensor.

That is why Parsonics approaches transducer selection around the complete application rather than a single specification.

Whether you are developing a new sensor, replacing an existing transducer, modifying an established design, or solving a difficult sensing problem, our team can help evaluate the acoustic and mechanical requirements of the application.

Standard, Modified, or Custom

Not every ultrasonic sensing application requires a completely new transducer. Parsonics helps customers determine the most practical path based on their requirements.

Standard Ultrasonic Transducers

Our standard product line provides proven transducer designs across a range of operating frequencies, sensing ranges, beam patterns, housing materials, and mounting configurations.

Standard transducers are a good starting point for OEMs and system designers when an existing model already meets the application’s acoustic, mechanical, and environmental requirements.

Modified Standard Transducers

Sometimes an existing design provides the required acoustic performance but needs to fit a different installation.

Depending on the application, Parsonics can review requirements involving housing materials, cable lengths, mounting configurations, thermal sensing, beam characteristics, mechanical dimensions, and other application-specific considerations.

This approach can provide a practical path between an off-the-shelf transducer and a completely new development. Describe your desired modification when you request a quote. 

Custom Ultrasonic Transducer Development

When a standard transducer cannot meet the requirements of the sensing system, Parsonics can work with your team on a custom solution.

Custom development begins with the application. Our engineers review factors such as operating frequency, sensing distance, target characteristics, beam requirements, environmental exposure, available mounting space, materials, temperature, cabling, and the drive and receive electronics.

The goal is not simply to create a different transducer. It is to develop a transducer that works as part of the complete sensing system.

Designed for Demanding Environments

Ultrasonic transducers often operate where moisture, chemicals, temperature changes, vibration, outdoor exposure, dust, and other environmental conditions can affect conventional sensing technologies.

Parsonics offers transducer configurations using materials including PVC, CPVC, Teflon®, Kynar® PVDF, and stainless steel depending on the model and application.

These material options allow the transducer construction to be matched more closely to the operating environment, including applications involving chemically aggressive materials.

Available Parsonics configurations also include IP68-rated options, CSA explosion-proof models, and models designed for applications requiring 3-A compliance.

Application considerations can include:

  • Chemical exposure and material compatibility
  • Operating temperature
  • Indoor or outdoor installation
  • Washdown and moisture exposure
  • Hazardous locations
  • Sanitary processing environments
  • Restricted mounting space
  • Vibration and mechanically noisy equipment
  • Long-range or close-range measurement
  • Narrow or broad beam requirements

Choosing the correct transducer construction can be just as important as choosing the operating frequency.

Engineering Support From Application to Production

The best transducer solution begins with understanding what the finished sensing system needs to accomplish.

1. Define the Application

We start with the measurement task and target. This may include liquid level, solid level, distance, proximity, object detection, open channel flow, obstacle avoidance, or another ultrasonic sensing requirement.

2. Review the Requirements

Our team evaluates the factors that can influence transducer performance, including sensing range, target material, frequency, beam angle, mounting, temperature, environmental exposure, housing material, cable configuration, and electronics.

3. Select or Develop the Transducer

If a standard Parsonics transducer meets the requirements, we can identify an appropriate starting point. If modifications or a custom design are required, we can review those requirements with your engineering team.

4. Integrate Into the Sensing System

The transducer does not operate in isolation. Drive voltage, receive circuitry, signal processing, mounting, and mechanical integration can all influence usable sensing performance. Understanding these relationships early can help avoid problems later in development.

5. Move Toward Production

For OEM applications, the objective is a transducer configuration that can become a dependable component of the finished system rather than a temporary laboratory solution.

Performance Starts With the Transducer

Reliable ultrasonic measurement depends on the interaction between the transducer, the target, the environment, the mounting arrangement, and the electronics.

Frequency influences attenuation and usable range. Beam angle influences sensing coverage and target discrimination. Housing materials influence environmental compatibility. Mechanical mounting can influence transducer ringing. Temperature can affect both the transducer and the speed of sound.

These factors become especially important when developing sensing systems for difficult targets, long distances, chemically aggressive environments, tight mounting locations, or demanding industrial equipment.

Parsonics combines ultrasonic transducer manufacturing with application-focused engineering support to help customers consider these factors before the transducer becomes part of the finished design.
