FSG Set Poing Adjuster

 for presetting of reference variables in control circuits

For presetting of reference variables

in analogue computing and regulating circuits, set-point

adjusters are used as control desk instruments in flush

mounting format or motor-driven potentiometers are used

for switch cabinet mounting.

For providing the set-point output, they contain mainly single or multiple ganging potentiometers with resistor output and

with current or voltage output respectively, associated with

a built-in signal converter. Inductive transducer systems with

current output or optoelectronic systems with digital output are available as well.

All types of transducer systems can be equipped with floating reversing switches for end-point limitation. The presetting of

the set-point is carried out mostly by hand with a rotary type

control knob on a dial of flush mounting instruments or carried

out with motor-driven potentiometers, additionally by means of set pulses with a d.c. motor or an a.c. motor (synchronous motor). Graduation of the scale, scale angle and colour of the scale are optional according to user requirements.

Motor-driven potentiometers are mostly used as set-point

adjusters in regulating circuits. Frequently they are used as

signal converter as well, for instance as

  • current/voltage-to-resistance converter
  • measured value memory or measured value delay unit
  • servo system in compensating circuits for analogue

           indicators

Especially for servo systems, the motor-driven potentiometer

of series M7-G3O-PK613 serves in transformers or indicating instruments.

In connection with an appropriate servo-amplifier,

inexpensive high precision indirect-acting measuring

instruments can be realized easily for indicating purposes,

for instance in

  • large-scale indicators for the display of

          braking force in motor

          vehicle operational monitoring systems
