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.
