Abstract

The control center (1) receives and processes incoming signals from and sends commands and information data to field instrumentation generally referred to by reference numeral (4 and 5). Instrumentation (4) includes devices located in a hazardous area (6). Instrumentation (4) could comprise, for example, devices of sensor, detectors, actuators, switches, petitioners, transmitters, comtroller and analyzer could perform the functions of measuring, sensing controlling positioning, calculating, communicating processing, displaying, discrete data collecting and providing an alarm function. Equipment (11) is a diaphragm actuated control valve.
