Potentiometer Command Signal Generator

Brand: Proportion-Air, Inc

Need an easy method of providing an electronic command signal to a control valve? Proportion-Air’s electronic control valves usually control to a set point pressure value that is provided by an analog command or reference signal.

These analog command signals are 0-10VDC, 4-20mA DC, or 0-5VDC with many special options readily available.

Often users already have a PLC or computer host integrated into their machinery which can provide these signals via an analog card or analog output module.

However, for bench top testing and other human controlled interface applications, a PLC is neither available or desired.

Proportion-Air offers several possibilities of easily constructed analog command sources.
  • Rotary potentiometer command signal generators
  • Signal conditioned to provide a linear analog output signal
  • Available as 0-10 VDC or 4-20 mA output signal
  • Available in one-turn and ten-turn design
  • Available with numeric indicator
