The force sensor works to the principle of center-line force measurement. You can record traction forces at lifts, cranes and housings, or twistings of masts, towers or platforms. The force sensor is a threaded rod. This allows easy and universal fastening. The application chamber for the resistance strain gauge is protected from mechanical and chemical damage by an aluminium tube, cast with a highly elastic compound. Full bridges of resistance strain gauges measure the elongation and lateral expansion caused by traction forces.
