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
