ABSTRACT:
A sensor is provided in one illustrative embodiment that includes a microcontroller that executes a program that generates quadrature output signals that indicate the change in a parameter being measured. As an example, the sensor could comprise a linear position transducer. The quadrature output signals can comprise square wave signals that are ninety degrees out of phase, each transition of the signals representing a unit of change in position of the measured mass. According to another aspect, the quadrature signals can be placed into phase with one another to indicate an error condition. In another aspect, user inputs can be provided to allow the user to select parameters such as frequency, update rate, and/or resolution. Moreover, at least one of the sensor inputs can be utilized to load calibration factor data for the sensor.
