E/P transmitter for remote locations
The EPX2 Voltage-to-Pressure (E/P) transmitter can use natural gas as its pneumatic supply, making it suitable for remote locations with solar power and no separate air supply
The EPX2 E/P transmitter from Moore Industries is designed for use with normal instrument air, but it can also be powered by natural gas, making it possible to use the transmitter in remote locations where no electrical power is available to drive air compressors The extremely 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 Voltage-to-Pressure (E/P) Transmitter accepts a voltage input signal from a DCS, PLC or PC-based control system and converts it to a pneumatic signal to drive and control valves, actuators and other pneumatically-controlled devices.
Accuracy is +/-0.25% of span including the combined effects of linearity, hysteresis and repeatability.
It maintains accuracy even when the supply pressure fluctuates between 20 and 40psig.
The EPX2 has a NEMA 4X explosion-proof housing and is protected from environmental problems, including dirt, noise and temperature extremes.
A large orifice, combined with an easily replaceable internal filter, protects against clogging caused by debris.
The EPX2 has RFI/EMI protection, shock and vibration protection that meets SAMA PMC 31.1, and it works in temperatures from -40C to +85C (-40F to +185F) and humidity of 0-100%RH, non-condensing.
