KINAX SR 719
Programmable Transmitter for Position Feedback
The incorporated KINAX 2W2 consists of 2 main parts: the diffe-
rential screen capacitor D and the electronic circuitry E (Fig. 5).

Fig. 5. Block diagram.
The angular defl ection α of the axle is transferred to the rotor R
of the differential screen capacitor with the aid of a mechanical
coupling. It is then converted into a change of capacitance pro-
portional to the angle.
All changes to the position of the rotor result in a change in the
capacitance at the input to the microprocessor. This is transformed
into a DC current signal proportional to the measured value.

software.

Programming
A PC, the programming cable PK 610 plus ancillary cable and the
confi guration software 2W2 are required to program the transmitter.
(Details of the programming cable and the software are to be found
in the separate data sheet: PK 610 Le.)
The connections between
"PC ↔ PK 610 ↔ KINAX SR 719" can seen from Fig. 7. The
transmitter can be programmed either with or without the power
supply connected.
The software 2W2 is supplied on one CD and runs under
Windows 95 or higher.
The programming cable PK 610 adjusts the signal level between
the PC and the transmitter KINAX SR 719.
