Angle Sensor with Analog Output Report by SoYoung Park, Feb 2007

I chose AWS angle sensor fromASM that can measure angle. They have various type of angle sensors. You can choose measurement range and output type when you order. They are supplied as potentiometers or with calibrated voltage or current outputs and the measurement ranges are 345/ 180/ 90.
