Cantilever Sensor delivers precise blade strains for wind turbine control.
Rudolstadt, Germany – April 2025
Bachmann’s Cantilever Sensor (CLS) is a flexible and multifunctional sensor that covers a broad range of applications. It delivers a temperature-compensated and strain-proportional current signal for determining the strains acting on the rotor blade.
In addition to detecting strains in rotor blades, the CSL can also be implemented as part of a Structural Health Monitoring system (SHM) for measuring strains in tower and foundation structures.
Since it is far less susceptible to local material inhomogeneities, it offers a high level of measurement accuracy. By design, it measures over a greater length than conventional strain gauges are able to measure.
The sensor offers complete force-free measurement. This means that the sensor element is neither subject to an adhesive bond, nor is it subject to mechanical aging and both have negative effects on signal quality. While conventional strain gauges and their large-area adhesive bond show signs of aging even after short periods of use, the CLS is characterized by its robustness and long service life over the entire life cycle of the wind turbine, with no degradation of signal quality.
The Bachmann CLS provides an analog output signal that can easily be further processed in data acquisition systems to determine the required strain information and transmit this information to the analysis system.
