Yokogawa MLXYokogawa Corp. recently unveiled its MLX loop-powered indicator, which incorporates the LCD from the company’s EJX pressure transmitter into a NEMA 4X aluminum housing. The company believes that the MLX is also characterized by:

  • An additional view of the measured value of flow, pressure, liquid level or temperature between a field instrument and the control room.
  • A 6-digit numerical display with a range of ±999999, a 6-digit alphanumeric display for engineering units and a 20-segment bar graph indicating 0 to 100 percent of full scale.
  • Operation from a 4- to 20-mA DC input.
  • The capability to extract the square root from the 4- to 20-mA signal sent by the differential flow/pressure transmitter displaying the actual flow reading to aid in flow measurement.
  • Configurability of the numerical and alphanumeric displays to show desired numbers and engineering units.
  • Horizontal or vertical mounting on a 2-inch pipe.
  • Suitability for use in potentially hazardous environments.
  • Compliance with FM explosion-proof requirements.
  • Epoxy resin or polyurethane-epoxy paint options, in addition to an optional calibration range and scale, and stainless steel tag.
