WFx Explosionproof Melt Pressure Transmitter (Oil-filled) - 2-wire 4-20 mA

  • WFx Explosionproof Melt Pressure Transmitter (Oil-filled) - 2-wire 4-20 mA


    • The entire amplifier/sensor assembly of an WF Series Melt Pressure Transmitter is packaged in a stainless steel welded enclosure with a conduit cable fitting.
    • This metal enclosure is completely sealed from the atmosphere, and is approved to meet hazardous area requirements.
    • The WF converts applied pressure at the point of measurement to a proportional voltage output signal. An amplifier converts the strain gage signal to a 4-20 mA output.
    • The small capillary tube filled with a special medium isolates the amplifier from potential thermal damage.
