POWERED BY THE CURRENT LOOP
LPM series is a 4 ½ LCD-digit process meter that is powered by a current loop (4-20 or 10-50 mA), has an optional loop powered backlight (red or green) and is RS232/485/USB compatible. Only two wires are required (in series with the loop) to make the process meter work as a basic loop powered display. OTEK; 520/748-7900; www.otekcorp.com
