From the determined forces can be concluded, for example, on the viscosity of the reactant or the product. For example, when a monomer is converted to a polymer, the viscosity in the product space increases along the lengthwise direction of the housing from the entry to the discharge. This also means that the pressure which is applied by the kneading elements to the educt or the product increases.

  • the measurement should take place at a suitable location.
  • the probe must not substantially reduce the mechanical load capacity of the shaft and, since the measurement is made by elastic deflection of the shaft elements, it must be made at a point where the deflection is maximum. It must also be possible to extrapolate from the measurement a picture of the total load, since the probe can probably not be installed at a point of maximum load, but only in their neighborhood. This results from the above requirement that the shaft or its elements must not be weakened by the probe.
  • the extrapolation of the measured data can be carried out according to the invention by empirical correlations or finite element methods.

This can be done visually with the mounting hole open or by marking the angular position at the shaft end. Alternatively, the angular position can also be determined by an angle measurement and the drive can be controlled accordingly so that it stops exactly at the suitable angular position.

From these considerations, it can be seen that the measurements of the forces on the shaft also allow a process control, or control the process so that loads on the shaft can be quantitatively influenced and thus controlled.
  • process control is meant that states, such as pressure, product degree of filling, product temperature, are influenced by suitable measures on process engineering apparatus that are connected to the process space. These measures may e.g. be that the degree of filling of a product in the process space by pumping or moving product by means of screws in and out of the product space is changed.
  • the temperature can be changed by changing the heating of the shafts or the housing of the product space. Both can have an impact on the local stress situation in the process room.

It is also particularly suitable if the product supply or removal is distributed over several points along the axis of rotation, since then an additional possible local control of the process and thus the local mechanical load condition is possible. Also, process engineering manipulations in the process space itself, such as a weir height for Greingna, or the speed of the shaft or shafts according to the invention can be used.
