1. A process transmitter for measuring a process variable, the process transmitter comprising:
- a first process sensor for measuring a process variable of an industrial process and generating a sensor signal;
transmitter circuitry connected to the first process sensor and configured to operate functions of the process transmitter;
a housing having a window; and
an image projector connected to the transmitter circuitry, the image projector configured to emit light to project an image of information parameters relating to functions of the process transmitter onto the window in the housing.

Abstract
An industrial process transmitter includes a first process sensor, transmitter circuitry, a housing and an image projector. The first process sensor measures a process variable of an industrial process and generates a sensor signal. The transmitter circuitry is connected to the first process sensor and is configured to operate functions of the process transmitter. The housing includes a window and an image projector. The image projector is connected to the transmitter circuitry and is configured to project an image of information relating to functions of the process transmitter onto the window in the housing.
