What is the vernacular to describe an rf transmitter w/rotary knob that turns a servo/motor 1:1? Answered
I'm barely schooled in robotics and RC. Seems I'm searching for a needle in a haystack without the precise terminology.
I'd like to turn a knob on a remote chassis. The knob presently turns manually from stop to stop approximately six times. It meters L/min of air. Low torque equivalent to about average for volume/bass/treble controls on a stereo.
I'd like to be enabled to turn this knob at an indexible 1:1 ratio with a handheld remote transmitter that utilizes a likewise rotary knob.
Once the servo/stepper or other is mounted axially to the chassis mounted knob and powered by a wall transformer, the hand held remote need not be indexed to match it precisely. 1/4 ID hose attaches to the unit and a L/min flow meter is attached to the remote.
Rf would be highly desirable. If necessary, or practical, I'd go with a wired rotary encoder/controller to accomplish the same. I'm unable to find either option after a day of searching online.
Fully willing to cannibalize existing products as well. It's sometimes much easier and cheaper way to go.
