Abstract
An analog output current transmitter includes a first circuit portion that generates analog sine and cosine voltage signals, a second circuit portion that transforms the analog sine and cosine voltage signals into current signals, the signals being transformed by an operational transconductance amplifier, and a third circuit portion providing a current limiter, the current limiter circuitry limits the output current to a defined threshold. No microcontroller is required in order to monitor and regulate the output current to the defined threshold. Also a system and method for sensing shaft bearing shaft rotation over 360 mechanical degrees having an analog output current transmitter is provided.
