Computer controlled adapter unit for fluid system control

摘要

A unit is disclosed which enables computer operation of and data acquisition from a system requiring a fluid input and supplying data in electrical form at an output. The unit comprises a valve for supply of fluid between one and a plurality of selectable ports. A valve actuator brings the one port and a selected port into communication in response to a signal derived from a micro-computer. An A/D converter relays data derived from said system to the micro-computer in digital form. The unit is preferably adapted for communication with an external computer to permit programming of the micro-computer and data acquisition by this computer.
