Record bat calls with up to four microphones simultaneously and access your data remotely via 4G LTE.

The BATmode 2S is a modular bat monitoring system specially designed for the use on wind turbines. It mainly consists of a central detector unit, one microphone including the associated UltraSoundGate analog-to-digital converter from Avisoft Bioacoustics as well as an antenna. From a simple standard monitoring in the height of the nacelle of wind turbines with only one microphone up to bat call recordings with four microphones over the entire height of a measuring mast, a wide variety of measuring tasks can be realized cost-effectively with just one monitoring system. For additional microphones you will need a Microphone Extension Kit which includes an UltraSoundGate 116Hnbm-r and one microphone. A 4-channel UltraSoundGate 116Hnbm-r is also available (please send us an email at for more information).

Since measurements in the nacelle or tower wall of wind turbines as well as measurements on masts require completely different microphones, you can use for each measurement point the most suitable microphone. Choose between the GM50 or GM90 microphone discs specially designed for the installation in nacelles, the TM10 and TM20 for tower wall mounting or use the microphone TM20 on masts.

The system offers LTE mobile cellular network which allows you to remotely control the BATmode system and always have an eye on your system's performance. Thus, ascents to the nacelle become obsolete and costs are reduced. Furthermore, the time-consuming evaluation of the recorded data can be reduced to a minimum with the new ProBat-compatible automated call categorization and the analysis software BATscreen.

UltraSoundGate 116Hnbm

Each BATmode system needs at least one UltraSoundGate 116 Hnbm. This is a high sampling USB audio interface for the acoustic recording of bats in the BATmode system which is connected between the BAT mode unit and the microphone. The UltraSoundGate and its corresponding recording software "Avisoft RECORDER" were proved in the RENEBAT research projects superior to other systems with respect to the bat triggers selectiveness and allows to record more bat calls with less noise.
