Transmitter suits awkward locations
The EPX2 E/P transmitter from Moore Industries can be used in remote locations where no electrical power is available to drive air compressors.
The EPX2 E/P transmitter from Moore Industries 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 extremely low power requirement of 3mA at 12VDC allows it to be powered by a battery or solar panel at remote sites

Module unlocks potential of smart HART
Moore Industries' HIM smart HART loop interface and monitor allows up to three additional analogue process measurements from smart HART multivariable mass flow, level, pressure and pH transmitters.
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 for control of valves, actuators and other pneumatically-controlled devices.
Accuracy is +/-0.25% of span including the combined effects of linearity, hysteresis and repeatability.
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, shock and vibration protection that meets SAMA PMC 31.1, and it works in temperatures from -40C to +85C and humidity of 0-100%RH, noncondensing.
