Radar for Real time Monitoring Blade Tip Clearance Molas CL lidar rental
| Product introduction
In order to meet the special needs of fan tower clearance monitoring and improve the practicability, data reliability and environmental adaptability in this specific application field, MolasCL is equipped with three beam ranging and a set of special algorithms, including strong light (sunlight) interference filtering, rain, snow and sand dust interference filtering cluster fog interference recognition and dense fog recognition
| Application scenarios
The application of clearance radar on the stock units can prevent tower sweeping, remove the power limit of dangerous units and thus improve the power generation. The application of clearance radar on future units can reduce the blade cost and reduce the design pressure of units.

| Product Features
Through the calibration process, the radar laser beam forms an inclination towards the impeller surface, so that the laser beam is located at the clearance point to be monitored at the lowest position of the impeller (at the blade tip height). When the blade runs, bends towards the tower side, and touches the beam, the radar can measure the radial distance between the blade and it, and the clearance value can be calculated through a certain inversion algorithm.
