Model F6804 Ring force transducer<\/h4>\n

For screw forces up to 450 kN<\/p>\n

\n

The force transducers of the F6804 series are suitable for the measurement of compression forces and are available with nominal loads of 3 kN to 450 kN. This force transducer has been designed with a ring geometry and constructed, specifically, for the measurement of screw and preload forces.<\/p>\n

The field of application of this force transducer are applications such as measurement and test equipment in which, for example, screw or bolt forces are measured. In addition, the force on spindle drives or general force can be measured using a ring geometry.<\/p>\n

Fields of application include the simple determination of bolt preloads where the force transducer is used as a measuring washer.<\/p>\n<\/div>\n

\n

Note<\/strong>
\nTo avoid overloading, it is advantageous to connect the force transducer electrically during assembly and to monitor the measured value.<\/p>\n

The measuring force must be introduced through the centre and free of transverse force. When assembling the force transducer, care should be taken that the support surface is flat, ground and sufficiently hard.<\/p>\n

Due to its small geometry, this force transducer reacts very sensitively to changing or different mounting positions.<\/p>\n<\/div>\n
