It is used by many high end watch manufacturers for measuring the friction in the movement of mechanical watches and is also used in various medical applications. The MBB-02 is entirely made of aluminum to combine lightness and stability of measurement. It has a nominal capacity range of 0.01  to 5  and uses semi-conductor strain gauges. N N Having a larger gauge factor than foil types, semiconductor strain gauges allow the measurement of very small strain. The sensor integrates a built-in overload protection offering up to 25 times security. Dedicated to laboratory applications, it is suitable for a temperature range of +15 °C to +25 °C. It can be easily connected to a PC or display unit through an external Wheatstone bridge amplifier. A version for Air Humidity compensation in ranges of 30 % to 60 % HR is also available. Applied force radially acts on the sensors pin which can be independently positioned in 2 different locations, thus offering more operating flexibility. Special versions with various cable lengths and connector outputs are also available. APPLICATIONS The compact dimensions of the MBB-02 allows adaptation to a wide range of small and precision applications (watchmaking for example) as well as long term dynamic measurements.
