Why standard transducers from SECO Sensor?
Our proven standard transducers are optimized for use in numerous classic ultrasonic applications, such as presence detection, distance measurement or level measurement. We manufacture in stable processes and large quantities. Our combination of high-quality materials and an experienced team of experts enables us to produce ultrasonic transducers of the highest quality.
High-quality materials – for outstanding quality
Our aim is to build high-quality, durable and robust ultrasonic transducers with outstanding electro-acoustic properties. We pay particular attention to the four main components: piezo disk, matching material, potting compound and stranded wire. With many years of experience, we manufacture our own material for this or source it from reliable suppliers with the highest quality standards. In this way, we ensure that our customers receive only the best products – with every ultrasonic transducer that leaves our company.
Piezo disk
We source our piezoceramic transducers from selected suppliers with above-average quality standards. Our main German supplier manufactures a material specially specified for us. This is characterized by a high degree of efficiency as well as minimal geometric and electrical tolerances.
Matching material
We produce our matching material in-house according to our own proven recipes. To achieve the best possible results, we use a particularly light, pressure-resistant epoxy filled with hollow glass beads, which is subject to only minimal fluctuations compared to products from external suppliers.
Potting compound
Potting with our specially formulated, soft-elastic polyurethane foams gives your transducer both mechanical stability and excellent structure-borne sound suppression – especially in cold conditions. We use customized potting compound recipes to achieve optimum acoustic parameters, adapted to your requirements.
Stranded wire
We mainly assemble our coaxial, Teflon and PVC strands ourselves. This enables us to ensure the highest quality and implement customer-specific adaptations quickly and easily. Short delivery times are also possible for special sizes. Our direct access to the production process allows us to carry out close checks and ensure consistently high strand quality, e.g. in accordance with IPC-A-610, class 3.
Our experienced team – for your success
For us, our employees are more than just anonymous cogwheels. Our corporate culture is characterized by flat hierarchies and open, respectful communication. Together, we manufacture ultrasonic transducers of outstanding quality with great expertise. Your satisfaction is our goal – we work on it every day.

“We develop an innovative solution for almost every measuring task. Individual support and intensive discussions with our customers are particularly important to us. From the initial idea to prototype construction and series production, we rely on a close exchange of ideas and qualified technical advice.”
“For offshore systems, we also equip our anemometer transducers with an optional scratch-resistant, water and dirt-repellent protective coating. This prevents droplet formation on the surface and icing of the front surface.”
“SECO Sensor is increasing its presence on social media. Contact and networking via LinkedIn and online channels is also increasing. However, traditional trade fair visits, personal customer appointments and technical workshops for maintaining existing customers and acquiring new customers are just as important to us.”
“Our direct access to the production process allows us to carry out close checks and guarantees consistently high quality.”

Further information
Standard transducers from SECO Sensor – precision meets versatility
SECO Sensor offers a comprehensive range of standard transducers specially developed for applications in air and gaseous media. These ultrasonic transducers are characterized by their robustness and reliability, even under difficult conditions such as dust, fog or darkness.
The product range includes three types of standard transducers.
- Multi-use transducer Compact all-rounders with high echo voltage and large beam width . They are ideal for applications with short to medium ranges.
- Focused transducers: Ideal for long ranges thanks to a well-focused sound beam and small beam width. They offer high quality and echo voltage, which makes them particularly suitable for precise measurement tasks.
- Pulsed transducers: Specialists for fast measurements at close range with a very high repetition rate and short ringout time.
SECO standard transducers cover frequency ranges from 80 to 500 kHz and, depending on the type, achieve ranges from a few centimetres to several meters. Thanks to their modular design and optional adaptations, they can be flexibly adapted to specific sensor requirements.
With almost 30 years of experience in the development and production of ultrasonic transducers, SECO Sensor stands for quality “Made in Germany”. The standard transducers are available immediately and offer a cost-effective solution for a wide range of industrial applications. Discover the world of standard transducers from SECO Sensor and find the optimal solution for your measuring task.
