Pencil P r o g r a m m i n g — N o cams to cut. Superimposed Recording — PreKorder's permanent record of process performance on a program chart overlay permits continuous visual comparison of record and chart. Programmed Limits—To trigger alarm or shut-down circuits in case of process malfunction, just pencil allowable operating limits on the recording chart. Programmed Gain — Varying the space between pencilled program lines varies the proportional control band or system gain.
Typical PrcKorder applications are in programming temperature, pressure, power, load, flow, position, and other process variables. Both round and stripchart models are available.
