scope:

The present guideline applies to 4-channel force measuring devices for determining radial clamping forces and their distribution in spring band hose clamps. Load is applied via four pins located at right angles to each other and pointing to the centre of the circular clamp. Each pin is connected to a suitable force transducer.

This guideline applies to static force measurement for determining the force distribution of the four point forces of spring band hose clamps, for example, as specified in DIN 3021. On the basis of DIN EN ISO 7500-1, procedures are described for calibrating 4-channel force measuring devices.

Note: External calibration of a force sensor of the 4-channel force measuring device is no replacement for calibrating the measuring chain when the sensor is installed. From this emerges the necessity of generating force for a comparative calibration using a reference measuring system.
