Precisely measure wind speed and direction – even in stormy times.
A typical anemometer consists of two pairs of opposing ultrasonic transducers arranged at 90° to each other. By means of an exact differential measurement of the respective sound travel times, the speed and direction of the wind can be determined quickly, precisely and maintenance-free. For a reliable measurement in cold measuring environments, we are happy to equip the ultrasonic transducers with a suitable heater.
- wide opening angle for a strong signal even at high wind speeds
- reliable measurement below freezing point
- precise, robust and maintenance-free
Application examples: Wind turbines, weather stations, smart-home applications
Typical transducers: SC029, SC031
Maintenance and calibration-free – exact flow measurement via ultrasound
The flow measurement typically works with two ultrasonic transducers in transmitter- receiver mode. The sound path is at a defined angle to the direction of flow. From the difference in sound travel time, the flow velocity and thus the volume flow of the gas can be calculated quickly and accurately. Since ultrasonic flow measurement works without moving parts, the devices are absolutely wear- and maintenance-free.
- high repetition rates thanks to fast transient response
- small design ensures largely undisturbed flow conditions
- maintenance-free thanks to no moving parts
Application examples: Gas meters, spirometry, O2/CO2 sensors
Typical transducers: SC125, SC135, SC150
Close or far away? – Reliably detect distances
In distance measurement, ultrasonic transducers work in pulse-echo mode or transmitter-receiver mode. The distance between the transducer and the object is calculated from the propagation time of the signal. For long ranges, we recommend our focused ultrasonic transducers. Thanks to the high signal voltage and narrow detection range, you get reliable measurement values even at several metres. For measurements without a blind zone at close range, choose our pulsed transducers.
- high signal voltage and narrow sound lobe for long ranges
- Close-range transducer for measurement without blind zone
Application examples: Automation, agriculture, olive harvesters, tar machines
Typical transducers: SC007, SC008, SC010, SC012, SC020, SC023, SC029, SC030, SC031, SC040, SC050, SC135
Half full or half empty? – Measure fill levels precisely and contactlessly.
For continuous monitoring of the fill level in a container, an ultrasonic transducer operates using the pulse-echo method. The distance between the sensor and the level surface is calculated from the running time of the signal and the known speed of sound. For an exact measurement with a long range, we recommend our focused transducers. Thanks to the small opening angle, measurement in small vessels is also possible reliably.
- high signal voltage and narrow sound lobe
- reliable function even when wetted
- chemically resistant
Application examples: Level measurement from above on liquids and bulk solids, Level measurement in small vessels (e.g. pipettes)
Typical transducers: SC008, SC012, SC020, SC023, SC030, SC040, SC050, SC150
Double sheet control:
Everything simple? – Recognise double arches quickly and easily
In double sheet detection, two opposing ultrasonic transducers typically operate in transmitter-receiver mode. Based on the intensity of the transmitted signal, double or multiple layers are detected. For a measurement without crosstalk, we recommend arranging our ultrasonic transducers in the array design.
- high signal voltage for transmission measurement
- low crosstalk thanks to array design and narrow opening angle
- very fast measurements thanks to high repetition rate
Application examples: Offset printing, ATMs, desktop scanners, label recognition
Typical transducers: SC023, SC040, SC050, SC125, SC135, SC150
Web edge control:
Everything on track thanks to real-time web edge monitoring
In web edge control, two ultrasonic transducers are usually arranged opposite each other in a measuring fork. These operate in transmitter-receiver mode. The web material is inserted into the fork and is located in the sound path between the transmitter and receiver. Depending on the position of the web, the sound path is covered to varying degrees. Based on the intensity of the received signal, the position of the web edge is monitored in real time.
- Narrow opening angle for precise measurement
- Real-time measurement thanks to high repetition rate
- Wide measuring range due to transducer arrays
Application examples: Newspaper printing, paper industry, textile production
Typical transducers: SC023, SC031, SC125, SC135
