Functional Description
The double range force sensors measure the tension force in the material and transmit
the measuring values as mV signals to the electronic unit CMGZ622. The electronic
unit amplifies the mV signal depending on configuration. A digital input selects the
measuring range to be used for the control loop. If the material tension deviates too
much, the brake or the drive will be activated more ore less depending on
configuration.

Force Sensors
The force sensors are based on the flexion beam principle. The flexion is measured by
strain gauges and transmitted to the electronic unit as mV signal. Due to the
Wheatstone bridge wiring of the strain gauges, the measured value is depending also
to the power supply. So, the force sensors are supplied from the electronic unit by a
very accurate power supply.
