Through hole annular load cells
Type S-FOWA
Description
Ring force transducers or annual load cells are made of one-piece and easy to mount. They suit nearly every installation. Hydraulic ring force transducers are an efficient solution to measure anchor forces for example. Ring force transducers or annual load cells are used for reliable measurements of medium and small compression forces. Areas of applications are screw presses, cutting tools, propeller shafts and the measurement of bolt forces
