The Loop Leader+ loop-powered large display meters 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. The 2.8" 5-digit top display is used to display the process variable while the 1.5" 8-character alphanumeric bottom display can be used to display the units of measure or a tag. Feet and inches models display level in feet and inches on the top display while the 8-digit alphanumeric bottom line may be used to display a tag or custom message.
Further enhancing the display on these instruments is a 20-segment bargraph that also includes a numeric value of the percentage the bargraph represents. Free, PC-based, MeterView XL software that connects to the meter via a micro USB cable is available for programming and setup of the meters.
The PD4 is available in two configurations: Display only and with two solid-state relays and 4-20 mA analog output. All models come equipped with two open collector outputs and remote contacts. The open collector outputs are useful for alarm indication. The remote contacts can be used to remotely operate the four programming buttons, to acknowledge the relays, to start/stop a timer/stopwatch, and more. The relays can be programmed for alarm indication, on/off control, or pump alternation.
Finally, there are intrinsically safe versions of these instruments that can be installed in hazardous areas.
