Claims: or the setpoint pointer with scanning units incorporated

the measured value by means of a

1. Electronic controller for electrically measured pointer attached pointer flag, contactless physical measured variables, with one of the 5 handles. The input variable "X". A galvanometric measuring circuit that shows the actual value is thus created by the control unit, which has a scale for the actual value display and the setting of the measuring unit pointer with a flag. The setpoint, which displays one or more adjustable »W« , is determined by the position of the setpoint pointer. In the case of the pointer for the actual value display and the position “Af” equal to “W” , a switching process takes place via the corresponding control of a relay. Setpoint adjustment mechanism jointly coaxially The switching process can therefore only be carried out, with the galvanometric measuring mechanism executing a movement when the actual value pointer is intended exclusively for displaying the actual value. The measuring mechanism represents an active component for the control process at input 15 for the target / actual value comparison impact.

Setpoint activated by the setpoint arm or arms - Electronic temperature control potentiometers are also provided, known from the patent, which, for the purpose of checking the actual value with registration P21 63 800.6-32, is equipped with a separate differential display device that indicates that the scale (5 ) are for one or have a differential display that is set up over a pointer deflection of up to 360 ° and is arranged with the ring scale of a potentiometer. same axis position as the axis (3, 6) of the galva- In this device version, the display range of the nometric measuring mechanism (2) and the setpoint indicator are not located over the entire setting range of the controller, ger (7, 8) above the motherboard (1) 35 but only represents about ¹ S.

40 is "W" , a switching action is also carried out, but in contrast to the state of the art, without moving the actual value pointer.

The invention relates to an electronic Dis galvanometric measuring mechanism with actual value pointer see controller for electrically measured physical only serves to display the measured value. In the case of the measured variables with a galvanic object of the invention that displays the actual value, the measuring unit thus represents a nometric measuring unit which represents a scale for the actual passive component for the control process.

Such a controller represents an essential improvement 60 tronic controller according to the present invention serung compared to the known controllers, such as the fact that the scale for a pointer deflection up they are, for example, in the "Siemens-Zeitschrift", 41 set up to 360 ° and with the same axis position as (1967), No. 6, pp. 493 to 497, and in "elektrotech- the axes of the galvanometric measuring mechanism and the ulk ", No. 3, February 7, 1968, p. 35.
