Labkotec Oy has introduced a new generation ice detector, the LID-3300IP for use in wind turbine applications. The detector is especially designed for wind turbines operating in extremely harsh weather conditions.
The LID-3300IP Ice Detector is based on ultrasonic signal detection where the output signal weakens in the presence of ice. When a set alarm level is reached, the ice detector then automatically begins to either heat the rotor blades or stop the turbine operation. The ice detector sensors can be fitted to new and existing turbines regardless of the manufacturer. The ice sensors are also interchangeable and do not require calibration with the main control unit. The LID-3300IP is easy to connect to wind turbine control systems using a relay, current data, serial or TCP/IP interface and operates through a local area network. Data communication between the sensors and the control unit takes place via an RS-485 channel. Congealment status, alarms and parameters can be monitored and adjusted through an in-built web-based user interface. The unit allows for two analogue output signals so that both external temperatures and freezing conditions can be measured.
