The Wind Speed Alarm Controller PCE-WSAC 50W 230-ICA is useful for measuring the wind speed to help determine the preferred site for a wind turbine installation. The device also monitors the wind load on existing wind farms, as well as on cranes for safey purposes. Due to the integrated 4 ... 20-mA analogue output of the wind speed alarm controller, the measured data can also be transferred to other controllers for evaluation.
