No. Visual feedback by the operator of the position of his control lever is not enough in your case. If that action is amplified or powered by a secondary power source powering a secondary mechanism, then it is a servomechanism. If the operator used some kind of motor to turn his gate valve handle, and his action only operated that motor, then he would have a servomechanism in the basic sense of that word.If you say the operator functions as the feedback mechanism, then all valves, say a standard spool valve, or even simple gate/ball valve are servo valves by your attempt to define it having the operator act as the feed back mechanism in contrary to the definition.
That's the goal to expound thought (and communication) potential with deeper understanding and use of language.In this case it doesn't constrict thought at all, it clarifies it.
I just finished reading the comments from start to finish and wished I had done so before picking up my AGT L12
Switch driven hydraulic valves are very common as third functions but we just call them solenoid valves. Several use a solenoids to control a pilot section which controls the main spool. Some even have position sensors to have verification if they are open or closed but no one still calls them servos unless they can control position and maintain it everywhere between open and close.That's the goal to expound thought (and communication) potential with deeper understanding and use of language.
Agree. Also agree with industry accepted use of the terms.
Servo to describe hydraulic pilot is a fun stretch/reach imo, based on any definitions I've read, but also agree use in that case actually complicates things by being less descript (even if reader can make the same stretch/reach in definition)
No big deal though Ima keep referring to my EM 15 as pilot or hydro pilot. Saving 'servo' for if I ever manage to upgrade something like the thumb aux circuit to a switch driven action on the joystick.
what is this?An LVDT sensor
This is a good explination of it.what is this?
You realize this thread is about 5k Chinese mini excavators?This is a good explination of it.
Linear variable differential transformer - Wikipedia
They are not as precise as linear encoders but much less fragile and cheaper. They do good enough for use in servo/proportional valves except in the most critical processes requiring absolute control.
I do.You realize this thread is about 5k Chinese mini excavators?
My thoughts exactly. I dont get into correcting someYou realize this thread is about 5k Chinese mini excavators?
A Slight "misuse of the word" is 10k in differences in cost of the two types of equipment being discussed.My thoughts exactly. I dont get into correcting some
ones spelling, grammar or possible slightly misuse of a word. Dfkrug tries to explain things so that even I can understand it.
I for one appreciate his willingness to try and help people like me. I fail to see how this line of scrutiny helps any of us with our cheap baby diggers.
