  Introduction
  The instrument is a fully automatic autoclave controller. It is designed around a powerful micro-controller. As such, it is compact, very rugged and user-friendly. The field wiring is brought on to plug-in type of connectors, thereby reducing down time. The Man-Machine-Interface (MMI) consists of 16 characters by 2 line LCD display with back lit, 6 – keys membrane keypad. The instrument accepts 1no. RTD sensor as reference for control. Sensor break indication is provided and is displayed as “OPEN” against the process value. The control action is a proportioning on-off type of control with a SSR (solid state relay) drive output.
