The MLX is the latest addition to Yokogawa's family of loop powered indicators operating from a 4-20 mA DC input. This model uses the same explosion proof housing as the MLA, MLD, and MLD1 and incorporates the LCD display from the EJX pressure transmitter. The display itself contains a 6 digit numerical display, a 6 digit alphanumeric display for engineering units and a 20 segment bar graph indicating 0 to 100% of full scale. The display is user configurable to show the desired engineering units. Another unique feature is square root extraction from a pressure transmitter signal for flow measurement. Please consult our general specification or instruction manual regarding product related details, options, mounting and wiring.

Yokogawa Meters and Instruments Division in Newnan, Georgia, have introduced their new Field Mounted Loop Indicator, which has CE and ATEX Intrinsically Safe Approval.
The Model MLD1 accepts a 2 wire 4-20 MADC input with less than a 1 volt drop at 20 MADC. The 3 ½ digit LCD display is fully adjustable +/- 1999 and has an accuracy of +/- 1 digit.
The 4.3" instrument has an aluminum alloy case and cover, which can be mounted on a nominal 2" pipe mount or surface; either horizontal or vertical.
The new MLD1, with its safety approvals, is a welcome addition to the already popular Loop Powered Indicators which Yokogawa has to offer with the MLA and MLD series.
The Model MLA is an Analog Loop Indicator with customer defined scale and range. The Model MLD is a Digital Loop Indicator with 4-20 MADC input. Both have FM and CSA approval, but not CE and ATEX approval like the MLD1
With the CE and ATEX certification and approval, Yokogawa is able to expand their business in the process industry world wide.
Additional standard specifications include:

• Decimal Point is selectable by DIP switch
• Ambient Temperature: -10-70 C
• Over range +/- 200 ma without damage
• Vibration: 3G @9-80Hz, 1G @80-150Hz
• Electrical connection: ½ NPT female
• Weight: 2.7 lbs

MLA series loop indicators are designed to meet FM standards for use in hazardous locations. The Model MLA field mounted indicators receive DC voltage or curent signal inputs from electroniic transmitters and indicate process mearsurement values. They accept 4 - 20 mA of DC input, 10 - 50 mA DC and 1 - 5 VDC. Mounting options are horizontal or vertical pipe mounting

MLD series loop indicators are designed to meet FM standards for use in hazardous locations. The Model MLD field mounted indicators receive DC voltage or curent signal inputs from electroniic transmitters and indicate process mearsurement values. Mounting options are horizontal or vertical pipe mounting.
