Bolt-on Strain Sensors

For wind turbine load testing, Applied Measurements has seen a significant rise in demand for its standard and custom-designed bolt-on load cells. The company’s BOSS series of bolt-on strain sensors is designed to be attached directly to steel structures, including wind turbines, and are capable of detecting tensile, compressive and bending stresses. These forces can then be converted to a useable electrical signal, either using instrumentation provided by Applied Measurements or by the customer’s own systems. Each BOSS strain sensor is manufactured from specifically selected high-grade alloy steel, with thermal coefficients of expansion matched to the structural steel of the wind turbine platform or blade. Each unit is temperature-cycled to ensure that the effects of temperature fluctuations are minimised.
