... what characterizes our anemometry transducer.

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.

The SC029, SC031 and SC042 ultrasonic transducers combine

  • sophisticated electroacoustic tuning
  • slim design with 8 to 10 mm diameter
  • cost effective design
  • wide aperture angle of approx. 13 to 20°
  • reliable measurement even in drifts & high wind forces

Also of interest:

  • resonance frequencies between 300 and 400 kHz
  • strong, clearly defined signal
  • short decay time at the same time
  • high repetition rates realizable
  • possible to sort the transducers in pairs or quartets

... how best to use our transducers.

For the installation of our ultrasonic transducers in your anemometer we recommend:

  • Arrangement of the 4 ultrasonic transducers for 4 cardinal directions
  • in pairs opposite each other, 90° offset to each other
  • Transmitter-receiver operation
  • classical transit time measurement
  • sinus burst excitation

Nice to know:

  • Temperature operating range without heating: -15°C … + 70°C
  • Maximum voltage: 150 Vpp
  • Temperature range extendable with in transducer integrated heating
  • Protection against water and dirt with lacquer coating

... which customizations are possible.

We are pleased to customize your ultrasonic transducers – according to your wishes and optimized for your specific measurement task.

Individualizable are for example:

  • direct mounting into your customized housing
  • optional heating for optimal operation even below freezing point
  • optional water and dirt repellent front surface sealing
  • crimp contacts on the connection leads
  • contacting with coaxial cables of any length
  • contacting with mini coaxial cables

We are also happy to optimize the electroacoustic parameters of your product according to your requirements – for example with a higher echo voltage or a narrower opening angle.

It is also possible to sort the transducers in pairs or quartets according to their electroacoustic properties for maximum synchronization during temperature changes.
