Ultrasonic functionality – convinces with reliability
Advantages & operating modes of our ultrasonic transducers
Why ultrasound?
The structure, design and functionality of ultrasonic sensors are the best arguments in their favor. The non-contact measurement results in a long service life that also impresses with minimal maintenance requirements. Our customers consistently rely on the use of ultrasound, particularly for use in difficult weather conditions.
Ultrasonic sensor functionality – two operating modes at a glance
Depending on the measuring task, SECO Sensor uses two different ways of operating the ultrasonic transducers. In both cases, the basis of the measuring principle is an ultrasonic transducer that emits a sound pulse (outside the audible range). However, the “processing” takes place in two different ways, depending on the requirements:
Transmitter-receiver operation
In transmitter-receiver operation, two transducers face each other, one of which acts as the transmitter and the other as the receiver. The ultrasonic signal is processed by the receiving transducer. Transmitter-receiver operation is suitable for flow measurement and wind measurement, but also for double sheet control and web edge control.
Pulse-echo operation
With the pulse-echo method, the sensor communicates with itself. This means that a sound pulse is emitted, reflected and received again as an “echo”. The transit time of the ultrasonic signal is measured. This operating mode is mainly used for presence detection, distance measurement and level measurement in small and large vessels.
Both ultrasonic methods work reliably and without contact – perfect for precise measurements with low wear and no ongoing costs for expensive maintenance, downtime or spare parts. We would be happy to advise you on the right ultrasonic function for your individual measuring task.

Individual developments for special challenges
In addition to proven standard transducers and customized products, SECO Sensor also offers ultrasonic solutions developed individually for customers. If no “off-the-shelf” transducer fits, we develop an innovative special solution in close cooperation with our customers – usually for particularly challenging environmental conditions, tight installation spaces, large temperature ranges or unusual measurement ideas.

Thematic background to the sensor, ultrasound and how the ultrasonic sensor works:
An ultrasonic sensor uses ultrasonic signals in its mode of operation. A sound pulse is emitted by the sensor, which is either picked up as a reflection or by an ultrasonic sensor positioned opposite. Ultrasonic sensors measure the distance to an object, for example, by determining the transit time of the ultrasonic signal. These can be solid, liquid or even gaseous objects. Thanks to the sonic mode of operation, the ultrasonic sensor works contactlessly, i.e. without direct contact with the object.
Transducers and sensors work with ultrasound, i.e. sound in the inaudible frequency range. The ultrasonic transducer forms the technical core of an ultrasonic sensor. Depending on the operating mode, it emits sound against a reflector and receives its own signal as an echo. Alternatively, it works as a transmitter together with a receiver. As there is no need for direct contact with an object and ultrasonic sensors are also minimally invasive when determining flows in air and gases, they are considered to be particularly durable. In addition, SECO Sensor specializes in the manufacture of particularly robustly designed transducers. Numerous innovative additional equipment options make the products resistant to environmental influences.
