Its low power requirement of 3mA at 12VDC allows it to be powered by a battery or solar panel at remote sites. Applications include offshore oil platforms, natural gas wellheads, oil wells, pipelines and similar locations that are far from electrical power. The three-wire EPX2 accepts a voltage input signal from a DCS, PLC or PC-based control system and converts it to a pneumatic signal for control of valves, actuators and other pneumatically-controlled devices. Accuracy is ±0.25 percent of span including the combined effects of linearity, hysteresis and repeatability. It maintains accuracy even when the supply pressure fluctuates between 20 and 40psig.
