Precision Digital PD4-6620 Loop Leader+ Large Display Loop-Powered Intrinsically Safe Flow Rate/Totalizer
Product Code: PD4-6620
Manufacturer: Precision Digital
The Loop Leader+ loop-powered large display flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. One of the most convenient features of these instruments is their large, dual-line display which is typically used to display flow rate on the 2.8″ 5-character alphanumeric top display and flow total, flow grand total, or a tag on the 1.5″ 8-character alphanumeric bottom display. Both display lines use 14-segment, alphanumeric characters that provide much clearer indication of tags, units, or alarm messages than 7-segment characters do. Further enhancing the display on these instruments is a 20-segment bar graph that also includes a numeric value of the percentage the bar graph represents.
The PD4-6628 is an intrinsically safe version that can be installed in hazardous areas.
