Beschreibung
Zusammenfassung:	A fluid sample system includes a control system that operates in the hazardous area and controls one or more valves and optionally receives outputs from one or more transducers and optionally one or more sensors. The fluid sample system includes components that operate in a hazardous area and includes a control system that operates in the hazardous area and that controls one or more electrical devices. The control system communicates across a barrier with a system on a safe side of the barrier with as few as two intrinsically safe couplings including a single pneumatic coupling and a communication link coupling. The control system includes an intrinsically safe voltage boost circuit.
