Transmitter Runs On Natural Gas

May 9, 2007
The EPX2  Voltage-to-Pressure (E/P) Transmitter is designed for use with normal instrument air, but it can also be used with natural gas, making it possible to use the transmitter in remote locations where no electrical power is available to drive air compressors.
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.
