ABSTRACT:
A light input energizes an optical transmitter providing a light output to a waveguide indicating a process variable. The transmitter has a process variable sensor generating a sensor output. An electrical circuit receives the sensor output and generates an electrical transmitter output indicating the process variable adjusted by a changeable parameter stored in the electrical circuit. The electrical circuit has an input energizing the circuit. An LED converts the electrical transmitter output to the light output. A gallium arsenide photodiode converts a first portion of received light into electrical energy provided to the energization input and converts a second portion of the received light into an electrical output controlling the stored parameter.
