- the measurement accuracy is reduced, which depends on the size of the measured transmissions of the oil-supplying beta-tube.
- a separate linear sensor is required; the presence of a screw also increases the value of the standard power supply.
- the linear sensor assembly which is sufficiently extended in the axial direction, increases the long dimensions of the screw and the power unit as a whole.
- the pulse signals of the signals are transmitted to the microprocessor to determine the angular position of the components at the momentary shift of the pulse signals.
- a particular part of the system is often generated by a pulse signal received by a consumer receiving a product from a household broadcasting machine.
- the range of changes in the volume of the oil supply of the beta-pipe to the selected installation angle is limited by the range of installation angles.
