Part number: 4.3880.xx.xxx
It has been developed especially for the application in harsh environments, and is eminently
suited for the use on wind power plants thanks to the compact construction and low weight.
The serial or analogue output of the data occurs optionally as instantaneous value or as moving average value with settable time frame.
If necessary, the instrument is automatically heated at critical ambient temperatures. The risk of malfunction by freezing is thus minimized. The ultrasonic transducers are heated, as well as all essential housing components.
