Yokogawa Corporation of America: Loop Powered Indicator for Explosion Proof Applications
The unit currently meets Factory Mutual or FM Explosion Proof requirements and will meet INMETRO, CSA, ATEX, IEC and Russian GOST in the near future.
The 4-20 mA powered MLX incorporates the LCD from the company's EJX pressure transmitter into a NEMA 4X aluminum housing. The unit features 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% of full scale. The numerical and alphanumeric displays are configurable to show the desired number and engineering units. Most LCDs used in loop powered indicators are typically 3.5, 4.5 or 5 digit displays. Another feature is root extraction to aid in flow measurement, extracting the square root from the 4-20 mA signal sent by the differential flow/pressure transmitter to display the actual flow reading. Other characteristics include 4-20 mA DC input, horizontal or vertical mount on 2-in. pipe, FM approval, epoxy resin or polyurethane-epoxy paint options, calibration range and scale option and stainless steel tag option.
