These models are among our most precise and yet mechanically robust miniature load cells. High accuracy, finely graded measuring ranges, small dimensions and the simple introduction of force via opposing threaded pins open up a wide scope of laboratory and production applications. Their sophisticated engineering with integrated support membranes and overload protection reduces additional design expense in many applications, e.g. for external overload protection or guiding the parts introducing force to the cell. The result is that less space is required, less material is used and less weight is involved. Last but not least, there is hardly any friction on components that could falsify the measurement result.
The force to be measured is introduced centrally and axially to the cylindrical sensor body in the tension or compression direction by means of the two threaded pins. This requires the sensor to be mounted without any elements touching the end faces of the sensor housing. Two stabilizing support membranes inside the sensors for the smaller measurement ranges minimize the effect of lateral forces and moments, while also ensuring long-term mechanical measuring stability. Even though the precision miniature load cell is designed to isolate the measuring element from external forces, torsion and bending moments on the sensor axis should be avoided. The sensors work position independent. They have an active side which acts directly on the measuring element, whereas the passive side is fixed to the housing.
