"to do" is that design from the ground up or put a board together and build or all three?
M.
What is the present output or device controlled by the accelerometer?
What is the reason for changing the encoder and why is it not working for you?
How is the process managed at present? Microprocessor? Logic etc?
M.
As will most rotary encoders. Yes, there are some that give absolute position, but that is not the norm.An accelerometer will only measure the RATE of change, not the absolute position.
....so you want to eliminate physical movement too? If something 'moves' you have 'mechanical parts'.The encoder we are using now, works fine, but we want to eliminate all mechanical parts.
Was this developed by you?, or for you?, or was it some off the shelf equipment?We are using a rotary encoder with a slotted disc and an optical coupler to measure the movement of a lever.
akWhat I hear:
Rather than couple the moving lever to a disc that rotates near an optical switch, you want to mount an accelerometer directly on the lever and run the flexible signal wires to the processing circuit, eliminating the mechanical alignment needed for the slotted disc / optical switch. Yes?

Most 3-axis accelerometer modules (MEMs) can sense Earth's gravity resolved along the axes, hence can sense tilt.You can get change in position from an accelerometer by integrating it twice.
Was this developed by you?, or for you?, or was it some off the shelf equipment?
If the former, what processor was used?
What is the reason for a desire to change the present set up?
M.
Typically the slot opto quoted and a slotted disc would be quadrature signals.What are the signals going to the uC: 1 sine/square wave, 2 sine/square waves (quadrature), something else?

What level of accuracy do you require?
