Efficient ice detector for icy conditions

LID-3300IP Ice Detector is designed for detecting icing conditions on the rotor blades. Ice reduces the productive capacity of wind turbines considerably and burdens their construction, which leads to an increased need for expensive and time-consuming maintenance.

Most wind turbines are located in the coastal regions with harsh weather conditions including icy winds, heavy frost and rapid temperature changes, so the need for efficient ice detection is evident. Equipping wind turbines with ice detectors can significantly reduce security risks and strain caused by ice formation.

Suitable for all turbines

The ultrasound-based Ice Detector offers many considerable advantages. The equipment is compact and easy to install. It is ready to use without calibration and fits all turbines from different manufacturers, including older models.

The LID-3300IP is easy to connect to wind turbine control systems using a relay, current output, serial or TCP/IP interface. Ice detection status, alarms and parameters can be monitored and adjusted through an inbuilt www user interface.

LID-3300IP Ice Detector system fulfils the requirements of PLd according to ISO 13849-1. Functional safety level PLd means advanced internal diagnostics by two independent microprocessors, secured control of ice and fault relay status, secured communication between control unit and sensor and more detailed fault detection and analysis. Only relay outputs are considered as safety outputs. Other outputs are possible and most suitable for certain purposes, but their safety features are not included to this functional safety assessment.

Market leader

Labkotec’s LID-3300IP Ice Detector improves turbine production reliability and radically reduces risks caused by ice formation in icy conditions. LID, tested and approved by DNV, and the Technical Research Centre of Finland (VTT), is the leader in the market. Thousands of units have been supplied to the biggest turbine manufacturers in Europe and in Finland they are used, for example, by Finavia to ensure aviation safety.
