  • Description

    This subminiature force sensor was optimised with respect to its height and is, at only 3.4 mm, the lowest known sensor with strain gauge 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.

    Examples of applications are

    • Adjustment of gauges
    • Force measurements on the inside of precision tools
    • Monitoring of control elements
    • Regulation of forces in medical technology
    • Control instruments in precision machinery
    • Adjustment and pre-load of devices
    • Measurement technology in aircraft construction
    • Fitting of test components and prototypes

    The subminiature 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 gauges 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 circular, however arranged circularly for measurement ranges ≤ 0 … 5 N.
