This miniature force sensor was optimised with respect to its height and is, at only 3.4 mm, the lowest known sensor with strain gage technology. Hardly higher than the diameter of its connection cable, it can also be housed in conditions where space is limited. Along with its minimal geometry, the force sensor is also particularly light. It has a high resonance frequency to follow quickly changing load alternations. Despite its extreme miniaturisation, in its application it remains completely robust and suitable for industry, not only with regard to the highly flexible cable connections or the full welding of sensors for the measurement ranges ≥ 0 … 10 N.
The miniature compression force sensors are flat, cylindrical discs with covered bottoms. The central load application button for taking on compression forces is an integrated part of the top, which is the sensor‘s membrane. On its bottom, the strain gages are fixed on the inside of the housing and interconnected with a full Wheatstone bridge. This passes on, for force applications, an output voltage which is directly proportional to the size of the measurement.
The connection cable exits radially from the sensor housing and is additionally stabilised by a case for measurement ranges ≥ 0 … 10 N. The support area of the bottom of the sensor is annular, however arranged as a circular area for measurement range 0 … 5 N.
